Great Crested Newts are the UK’s most strictly protected amphibian, requiring licensed ecological surveys if a development may affect them. As the first signs of spring emerge, ecologists are preparing for the start of this year’s newt survey season. Below, we have compiled a list of the most common newt survey methods and the equipment needed for each, so that you can ensure you have everything you need as the survey season approaches.

Netting

Netting for adult and larval newts can be a useful tool in both survey and relocation. Here at NHBS, we have designed an amphibian net specifically for the safe and efficient capture of newts. The net bag is attached by a wide velcro collar which prevents newts from becoming caught between the frame and the bag. The bag can also be removed from the frame to be disinfected between sites. The seams have been carefully placed so that they do not come into contact with the front edge of the net, and the material of the bag is a soft 2mm mesh. The net head is 300mm wide and comes with a sturdy, wooden 1.2m handle. We also sell a diamond-shaped amphibian net that comes in either standard depth or deep. Its shape is ideal for easy and safe capture for amphibians and is also available in a collapsible frame for easy transport between sites.

eDNA

The presence of Great Crested Newts can be determined by analysing pond water samples for newt DNA. This process is known as eDNA sampling and is a recent but very effective way of newt surveying that causes very little disturbance to the newts themselves. Provided that the sampling and analysis protocol complies with DEFRA guidance and that samples are collected between 15th April and 30th June, then eDNA test results are accepted by Natural England and Natural Resources Wales. This year, NHBS has once again teamed up with eDNA laboratory, Nature Metrics to deliver a complete Great Crested Newt eDNA analysis service. Combining our expertise in sourcing, packing and shipping equipment with the excellent laboratory proficiency of Nature Metrics, this partnership facilitates a fast and efficient service. If you would like to find out more about the eDNA services that Nature Metrics provide, please visit www.naturemetrics.co.uk

Dewsbury Trapping

The Dewsbury trap is an innovative design of newt refuge trap that is exclusive to NHBS. The clever design of this trap ensures that any trapped newts have access to both fresh air at the top of the trap and a thermally stable refuge at the bottom of the pond. They can be easily deployed from the edge of the pond meaning that not only is this trap safer for newts, but it is also safer and more convenient for surveyors too. In preliminary trials the Dewsbury trap was found to be more effective at catching newts than traditional bottle trapping methods and can be left unattended for up to 24 hours meaning night visits are not necessarily required.

Please note: we recommend that you contact your national licensing authority (Natural England, Natural Resources Wales, Scottish Natural Heritage, etc) before you purchase this trap. The Dewsbury Newt Trap is not included within either the Level 1 or Level 2 Natural England Class Survey Licence and a separate licence is required

Bottle Trapping

Bottle trapping is a popular method of surveying for both detecting and assessing populations. It can, however, become quite labour intensive, especially if you are looking to cut bottles into traps yourself. To save yourself some valuable time, we sell pre-cut bottle traps with the head inverted and ready to deploy. These can be bought in packs of 40 or 120 and are cut from 2l PET bottles with a 28mm neck diameter. Alternatively, we sell the whole bottles if you would rather cut the traps yourself.

Torching

Torching is a less invasive and effective method of counting/observing newts without the need for capturing them. Torches are recommended to be between 500,000 and one million candlepower and need to ideally last several hours at a time. The Cluson CB2 range is very popular among ecologists and provides 1 million candlepower with long lasting battery life and an easy-to-use pistol type grip. For a more lightweight and economical option, the LED Lenser is a powerful torch that offers up to 450 lumens and a sharply focused circular beam that can last up to 300 hours on a low power setting.

 

Drift Fencing

Fencing can either be used to temporarily exclude or contain newts in mitigation projects. It can also be used to aid the capture of newts for relocation and is typically a short barrier with the base buried underground. Our Tristar Newt Fencing comes in rolls of 100m, is made of UV stabilised polythene sheeting and tinted green. It is designed to resist weather damage and has a life expectancy of 5 years, making it ideal for temporary mitigation projects during development works. It is easy and simple to put up and can be fixed into place with our soft wood stakes.

Pitfall Traps

Often, pitfall traps are used alongside drift fencing in order to trap and translocate newts in relocation projects. They consist of a container that is buried underground often flush with the edge of drift fencing. Both square buckets and round buckets have been shown to be effective and we supply several options depending on your preferences.

NHBS Guide to small mammal survey equipment

Small mammals are common and widespread across many of our terrestrial ecosystems. They play a crucial role in ecosystem food-webs as key prey species for many carnivores and are also useful as indicator species for agricultural change and development. Consequently, surveys of small mammal populations can be a useful tool for ecologists, researchers, and conservationists alike.

Small mammals are most commonly monitored through the use of live traps. These allow a range of species to be monitored simultaneously and also allow biometric data such as weight and sex to be collected. In addition, estimates of population size and structure can be calculated using capture-mark-recapture (CMR) techniques. However, other more passive monitoring techniques such as dormouse nest tubes, hair tube, and footprint tunnels are also available. Below we will take a look at some of the most popular small mammal survey equipment.

Longworth Traps

Longworth traps have been widely used in the UK for many years. They are made from lightweight yet durable aluminium and have been consistently well documented in scientific literature and ecological reports.

The trap consists of two parts: a tunnel which contains the door tripping mechanism, and a nest box, which is attached to the back of the tunnel. The nest box provides a large space for food and bedding material to ensure that the trapped animal is comfortable until release. The sensitivity of the trigger mechanism can be adjusted depending on the target species, although Pygmy shrews have been known to be too light to trigger the mechanism. The door can be locked open for pre-baiting for ease of use.

The Longworth trap comes as two options: with a shrew hole or without a shrew hole (Please note that shrews are a protected species so ensure you are aware of the relevant laws in the country in which you are trapping).

Sherman Traps

Sherman Trap

Sherman traps are another popular live-trap which can be folded flat for ease of transport and storage. They work by a trigger platform which causes the entrance door to shut when an animal runs into the trap. Sherman traps are formed of one compartment and because of this, it can be difficult to add food/bedding into the trap without interfering with the trigger platform. The traps may also distort over time with repeated folding. Sherman traps come in a variety of sizes and lengths so that you can find a trap to best suit your target species and can be purchased as either an aluminium or galvanised version which is more resistant to rusting.

NHBS Water Vole Trap

If you are looking to trap and survey water voles, we offer a water vole trap which comprises an extra large (XLK) Sherman trap with its rear door removed and an attached nesting compartment. This trap is suitable for water vole survey, such as capture, mark, recapture studies, as well as water vole relocation projects.

 

Footprint Tunnel

Footprint tunnels are a less invasive method of surveying small mammals. Species presence/absence can be determined by examining the footprints made by mammals that have walked over an ink pad to reach the bait left in the tunnel. This method is especially useful for determining the presence of hedgehogs that are not otherwise easily ‘trapped’. The tunnel comes with a UK mammal footprint identification sheet; however it may be difficult to distinguish between some species of smaller mammals.

Squirrel Hair Traps

Squirrel hair traps are another non-invasive survey method that is designed for red squirrel survey. When squirrels pass through the baited trap, their hair is collected on sticky tabs within the tube. These hairs can then be analysed to determine whether red squirrels are present in the area.

 

Dormouse Tubes

Dormouse nest tubes are a cheap, easy and very popular method of determining the presence of dormice within a habitat. The tubes consist of a wooden tray and a nesting tube. Dormice make nests in the tubes and it is these that are used as indicators of their presence in the habitat. Dormice are legally protected in the UK and must not be handled unless you have a licence to do so. Nest tubes can be set up and checked without a licence until the first evidence of dormouse activity is found. After that, only a licensed handler can check them.

A note on licensing

Please note that some small mammal species are protected by law (e.g. shrews and dormice in the UK) and you must obtain a license from Natural England, Scottish Natural Heritage or the Natural Resources Wales if you set traps with the intention of trapping any species of shrew. Please ensure you are aware of and meet the requirements of any relevant laws in the country in which you are trapping.

Introducing new microplastics nets from NHBS

The destruction of aquatic ecosystems is a major issue facing conservationists globally – causes include microplastic pollution, acidification, global warming and over-fishing. The manufacturing team at NHBS have produced a series of new survey nets designed to help researchers gather data on microplastics and to sample plankton more efficiently. This blog describes the sea trials performed using our prototype nets to establish the optimal towing speeds and sea conditions as well as whether the nets worked effectively and were robust enough to withstand exposure to the marine environment.
Three new nets were tested – the Manta Trawl Net, which is designed to sample microplastics in calmer inshore waters and on rivers and lakes. The Avani Trawl Net, which is designed to sample microplastics in rougher, offshore environments and the Bongo Net (a pair of 300mm plankton nets joined in the middle and weighted with a depressor vane) which is designed to allow researchers to use two different mesh nets during a single trawl. Plymouth Sound was an ideal location, as we had both inshore and offshore designs to test and the breakwater provided us with easy access to both sheltered water and the open ocean.

The first design tested was the Bongo Net. The net performed very well. The sampling depth was easily adjusted by modulating the speed of the boat and the depressor vane kept the net level in the water.  In our tests the Bongo Net performed best at towing speeds of between two and four knots.

Bongo Net

Next, we tested our inshore Manta Trawl Net. The Manta Trawl Net is designed for microplastics sampling in calm inshore waters and on rivers and lakes. The Manta Trawl Net has a post box shaped aperture and twin ‘wings’ (manta wings) mounted onto the frame which serve to lift the net frame so that samples are efficiently collected at the top of the water column. This net was tested at a variety of towing speeds and performed best at speeds of between two and four knots.

Manta Trawl Net

The last net to be tested was The Avani Trawl Net. The Avani Trawl Net is designed for offshore microplastics sampling. The vertical orientation of the aperture of the net ensures that samples are collected from the top few centimetres of the water’s surface in slight to moderate swell conditions. To test this net, we ventured out beyond the breakwater where the swell was approximately 1-2m. The net stood upright and performed as expected at speeds of between four and eight knots when exposed to smaller waves of approximately one metre in height. When approaching larger waves, we found that the net had a slight tendency to cut into the side of the wave at speeds of between six and eight knots and that the net performed best at slightly lower speeds.

Avani Trawl Net
All of the nets functioned properly, and our haul included both microplastics and icthyoplankton (fish eggs and larvae). Both the frames and the nets also withstood the sea conditions well and we could find no faults with their design or build – all told a successful trial.
If you are interested in these nets look out for them in our 2019 catalogue, find them on nhbs.com, or contact us on customer.services@nhbs.com and we will send you more information as soon as it becomes available.

 

Watching Wildlife – Part 2 – Nest Box Cameras

This is part two of a two-part series that will look into different ways of watching wildlife in your back garden. Part 1 looked at trail cameras. In this second part, Antonia Peacock will take a look at nest box cameras and advise you on what to look out for when buying one.

There is a whole world of wildlife in our back gardens, but often these creatures can be elusive or hidden away.  Our range of wildlife equipment can offer you an amazing insight into their world from the comfort of your house, without the risk of disturbing your wildlife.

Come early spring, our garden birds will begin their breeding season. Placing a nest box in your garden will not only give breeding pairs a helping-hand in finding somewhere safe to have their young. But it also provides an opportunity for you to get up close and personal with the goings-on inside with the use of a nest box camera. There are several options and kits out there and a few things to think about when it comes to picking a nest box camera. Here, I will offer some advice and options to ensure you can find the kit that is right for you.

Wired, Wireless or WiFi?
The difference in nest box cameras come mainly in the way that you receive images from the camera itself. These are either wired, wireless or WiFi. Wired kits can provide better, higher quality, more reliable images, but are sometimes not as convenient as Wireless or WiFi kits. Note that even in wireless or WiFi kits, the camera itself still requires power from a nearby mains source (extension leads are available to buy separately.  Alternatively, wireless or WiFi cameras can be powered by an external rechargeable battery that can last up to 36 hours on one charge.

Kit Contents
If you are completely new to nest boxes and nest box cameras, complete kits are available with a nest camera already mounted inside a nest box. Alternatively, if you are looking to purchase a nest box camera, but you already have a nest box, then you can buy nest box cameras separately

Viewing your footage
You can view your footage in a variety of ways depending on what camera or extra equipment you have. Wired cameras plug straight into your TV with an AV cable (included in wired camera kits). If you would like to view and record footage on your laptop or computer instead, you can buy a USB video capture device for both Windows and MacOS. These devices come with software that enable you to set up motion detection or schedule recording, ensuring you don’t miss any exciting moments.

With wireless kits, the footage is transmitted to a receiver which can then plug directly into your TV or PC using the provided AV connectors. Alternatively like the wired cameras, you can use a USB capture device to enable PC or laptop recording.

WiFi cameras transmit their footage over their own WiFi connection. This means you can connect your smartphone, tablet or PC to the camera’s WiFi to view or record footage.

Watch live footage from anywhere in the world straight from your nest box with the live-streaming capabilities of the IP nest box camera, great to share with your friends and family. The camera plugs directly into your internet router or network switch via an included ethernet cable and once set up on a PC or smartphone app, you can share or watch your footage wherever you are in real-time.

If you need to use a wireless camera, a Digital Video Recorder kit is also capable of live-streaming. The wireless receiver can be plugged into the DVR which can be connected to your internet router to enable live-streaming. The DVR itself allows you to set up motion-detection or scheduled recording. You can also add up to four cameras to the DVR which may be useful if you want to watch from multiple angles or from multiple nest boxes.

Species
You may have a particular species of bird in mind that you are hoping to capture on your nest box camera. Our nest box camera kits with boxes are aimed towards common garden birds. The species of birds that you may attract depends on the entrance-hole size.

Nest box
Nest Box Camera Starter Kit

A 29mm hole, such as that of the Nest Box Camera Starter Kit, is suitable for Blue Tits, Coal Tits, Marsh Tits, Great Tits, Tree Sparrows and flycatchers. A larger 32mm hole, such as that of the Gardenature Nest Box Camera System, is suitable for House Sparrows, Nuthatches, Blue Tits, Coal Tits, Marsh Tits and Great Tits. It also has a removable front panel that is ideal if you are looking to attract robins or wrens.

Nest Box Camera Kit
Nest Box Camera Kit

The Nest Box Camera Kit has a removable 29mm plate that can attach over its 32mm hole meaning it is capable of attracting a range of species. If you are looking to attract anything larger or a more ‘picky’ species, then you may want to buy a species-specific nest box and fit one of our separate nest box cameras to this.

Staff Picks 2018

Welcome to our annual round-up of the books and equipment we have most enjoyed reading and using this year, all chosen by members of the NHBS team. Here are our choices for 2018!

 

A Pocket Guide to Wildflower Families 

I am a complete amateur when it comes to botanising. I have struggled in the past to make sense of botanical field guides, and they always left me feeling rather stupid and frustrated. This booklet came to my rescue on my walks this year, and helped me make sense of both the plants, and the features to recognise them by, and the field guides! The author, Faith Anstey wrote a great article for the NHBS blog, and with this blog and her Pocket Guide (and her other books), she has done an enormous service for those who need a friendly guiding hand.
Anneli – Senior Manager

 

Wilding

The process of returning the land to nature has a name that is rapidly entering the mainstream; ‘Rewilding’ or as Iasbella Tree’s book refers to ‘Wilding‘. The subject provokes great debate among conservationist and Isabella’s book certainly doesn’t sit on the fence when it comes to Knepp’s experiment. But her book is written with passion and knowledge and whatever your viewpoint, there is no doubt this book has put Rewilding onto the agenda and could be a game-changer when it comes the stewardship of our countryside in a post-Brexit Britain. Everyone who cares about wildlife and nature should read this book.
Nigel – Books and Publications

 

Seasearch Guide to Seaweeds of Britain and Ireland

As a Marine Biology Graduate I automatically drift to marine-based books, and the Seasearch Guide to Seaweeds of Britain and Ireland is no exception, climbing straight to the top of my field guide list. Finding an available, accessible, up-to-date guide to Britain and Ireland’s seaweeds is incredibly hard, especially one that covers all the Brown, Red and Green seaweeds! As an avid seaweed-presser I’m fascinated by seaweed diversity and this guide helps me find and identify the common, rare and invasive species that line our coasts, thanks to its detailed descriptions and distribution maps. I recommend all naturalists who have not yet attempted seaweed identification to seize this opportunity to branch out.
Kat- Editorial Assistant

 

Landfill

I have long considered gulls a paragon of the bird world, here’s a family whose numerous members excel in flight, at sea, and on land, even navigating the fast-changing urban landscape we have created, and not one of these facets kowtows to lessen another. In the wake of some popular gull identification guides in 2018, Tim Dee and the good folks at Little Toller bring us Landfill – a compact, thoughtful and beautifully crafted gem of a cultural companion to these adaptable birds. Landfill also highlights how our wasteful, short-sighted march has shaped their fortunes and our relationship with them.                                         Oli – Graphic Designer

 

BeePot Bee Hotel

The BeePot Bee Hotel is my favourite piece of equipment this year. It is stylish, sleek and is of course fantastic for bees! Solitary bees use this as a safe nesting space where they lay their eggs and where they can find refreshment from pollinator-friendly plants planted in the top. Ideal for gardeners or nature lovers! Check out the wider range of products which can be integrated into buildings here.             Bryony – Wildlife Equipment Specialist

 

The World in a Grain

The staff picks are becoming increasingly hard, as I have read even more books than last year. The World in a Grain is one of several books this year that made a large impression on me. Most people can name at least a few current or upcoming resource crises, but I doubt many people would rank sand amongst a natural resource that we could run out of any time soon. But, as Vince Beiser shows in this hard-hitting piece of investigative journalism, we are and the prospects are unsettling, to say the least. An excellent read that does not shy away from difficult questions and uncomfortable truths.

The Orchid

I’ve always loved orchids, despite my inability to grow them. The Orchid is an unusual and delightful book containing  many fascinating stories about this beautiful and ubiquitous plant. Supplemented with notes and letters from the Kew archives and 40 botanical prints featuring illustrations by great orchid artists such as John Day and Sarah Drake, it will make a great present for any orchid-devotee.
Soma – Marketing Coordinator

 

Droll Yankees Lifetime Seed Feeder

After starting to feed the birds in our outside space at NHBS, I quickly realised that the Droll Yankees Lifetime Seed Feeder was needed to provide our local birds with food  over the winter months! The prominent perch extensions and robust design makes this bird feeder my staff pick of 2018.                                                                 Marie – Warehouse Coordinator

 

Reindeer: An Arctic Life

I always get excited about a new Reindeer book, especially if it’s about the Cairngorm Reindeer Centre (my favourite place to be in the UK!). Reindeer: An Arctic Life is a wonderful introduction to a fascinating species with great facts and anecdotes throughout. You’ll learn so much about Reindeer evolution and behaviour and learn more about how the Cairngorm herd came to be.
Natt – Customer Service & Dispatch Manager

 

Eco Hedgehog Hole Fence Plate 

I once read somewhere that a hedgehog requires something like 20 average-sized gardens to forage in every night! The trouble is that with our tendency to surround our gardens with fortress-like wooden fences, we do not always make access easy for them. The Eco Hedgehog Hole Fence Plate is a nice way to neaten off and protect an access point for your garden visitors and, at the same time, helping to conserve our hedgehogs. You can even buy a pack of two and give one to your neighbour so that they can make their side of the fence look good too! Or go halves! There you go – neighbourly love and hedgehog conservation for very few pennies!                                                                              Jon- Wildlife Equipment Specialist 

 

NHBS Staff Picks 2017

Welcome to our annual round-up of the books and equipment we have most enjoyed reading and using this year, all chosen by members of the NHBS team. Here are our choices for 2017!

Winter Birds

Winter Birds

In Winter Birds, we find Lars Jonsson’s loving portraits of some of the birds that he observed in southern Gotland in the winter months; both the watercolours and the accompanying essays are wonderfully intimate and personal. A fascinating book to dip into on cold and windy evenings, even if (like me) you don’t know your finches from your jays. First published in Swedish two years ago, this is now available in a UK edition, with range maps for both Sweden and the British Isles alongside each species. Expertly translated by David Christie, this is one of my favourite books this year.
Anneli – Senior Manager

Orison for a Curlew: In Search of a Bird on the Brink of Extinction

The Slender Billed Curlew, Numenius tenuirostris, is emblematic of species decline and ultimately extinction. With the last fully-fledged sighting in Morocco in 1995, naturalist and traveller Horatio Clare took up the challenge of sighting this ethereal creature. With precision and clarity and in only 115 beautifully written pages, this book takes the reader on an immersing journey into history, politics, hunting and conservation.
Nigel – Books and Publications

Field Guide to Moths

Field Guide to the Moths of Great Britain and Ireland

As a newbie to the world of moths, this book is a definitive and indispensable guide to UK species (excluding micro-moths). With in-depth descriptions and distribution maps for each species and beautifully clear and concise illustrations, this newly updated guide is a valuable resource and must-have mothing companion, perfect for beginners and pros alike.
Oli – Graphic Designer

Why We Sleep

Why We Sleep: The New Science of Sleep and Dreams

Picking my favourite book of the year wasn’t easy this time, having stepped up my reading efforts this year. But since there has to be one: Why We Sleep is an exceedingly well-written book about the biology of human sleep, and especially the deleterious effects of chronic sleep deprivation that most of us subject ourselves to. Matthew Walker is a gifted writer with a knack for explaining neurobiological principles in clear language and using imaginative metaphors. It actually made me undertake some very serious attempts to change my sleeping habits.
Leon – Catalogue Editor

The Lost Words

For anyone even vaguely interested in nature writing Macfarlane needs no introduction.
His series on landscape, place and imagination has enthralled me since I first picked up The Old Ways several years ago.
Created in response to the nature-related words culled from the Oxford Junior Dictionary, words which are considered no longer relevant to a modern childhood, Macfarlane along with artist and author Jackie Morris have created a beautiful ‘spell book‘ for younger readers. A joyful celebration of both nature and language.
Johnny – Customer Services

Dinosaur MonopolyDinosaur Monopoly

Everyone at the NHBS board game club loved Dinosaur Monopoly. A new take on an old favourite, though we all agreed the T-Rex should not be the Mayfair of this board! Have fun excavating sites, bartering for ownership and making (or losing!) the big bucks!
Natt – Customer Service & Dispatch Manager

 

Petzl Tikka Headtorch

The Petzl Tikka is a brilliant head torch – with a light output of 200 lumens, you really get a lot of light for your money! Having five different light settings, it’s great for close up work, and with a range of 60m is ideal for night running/orienteering (with the added bonus of being weather resistant). From personal use, I would highly recommend this to anyone who is after a high quality head torch for a very reasonable price.
Sam – Customer Services

Mushrooms and Toadstools

Mushrooms and Toadstools of Britain & Europe: Volume 1

Mushrooms and Toadstools of Britain & Europe is the long-awaited field guide by Geoffrey Kibby, the highly respected field mycologist. This title stands out from other fungi guides with its detailed and comprehensive identification and field notes, but for me the real highlights are the gorgeous illustrations and diagrams running through the whole text. One doesn’t have to be a serious mycologist to appreciate the beauty of fungi as presented in this book!
Rachel – Customer Services

Kite Caiman Binoculars

Kite Caiman Binoculars

My pick is the 8 x 42 Kite Caiman Binoculars, which are our newest edition to the Kite binocular range. They have an amazing close focus and far reaching power, they’re affordable, bright, and are great quality. The Caimans make the ultimate pair of binoculars in the field for anyone on a budget.
Bryony – Wildlife Equipment Specialist

Squid Empire

Squid Empire: The Rise and Fall of the Cephalopods

Covering hundreds of millions of years, Squid Empire tells the fascinating story of how the squishy squids we have in our ocean today became what they are. Written with humanity and wit this book is extremely approachable, even by a layperson such as myself.
Luke – Web Developer

The Plant Messiah

In his time working at Kew Gardens, Carlos Magdalena has managed to track down and propogate some of the world’s most threatened plant species. Many of these success stories are shared in The Plant Messiah and all are recounted in Carlos’s enthusiastic and charismatic style. Part memoir, part “botany-101” and part plant elegy, I found this book difficult to put down, and whizzed through it in just a day or two. It is inspiring, thrilling and educational – what more could you ask for?
Luanne – Senior Editor

pH Meter Calibration and Maintenance

pH Meters
A pH meter is a key part of the field and lab worker’s tool kit.

Modern pH meters are extremely efficient and provide highly accurate results if they are well looked after and correctly calibrated. A key part of this is taking care of the pH electrode. In this post we will discuss how you can maintain the accuracy and lifespan of your equipment by following correct pH meter calibration, cleaning and storage guidelines.

The main components of the pH meter are the glass electrode and reference electrode which are housed together inside a thin glass membrane. The pH meter calculates pH by measuring the difference in potential, or voltage, between the two. A well cared for electrode will last for up to two years, although use at very high temperatures or with abrasive chemicals may reduce this. It is also important to make sure that you have the correct meter for your sample type: for example, a pH meter designed for use in soil samples will have a different electrode type to one which is designed for liquids.

To maximise the lifespan of your electrode and ensure that it provides consistently accurate readings, a small amount of care and attention is required. Below we answer the most common questions relating to pH meter calibration and care.

How do I calibrate my pH meter?

193227pH meter calibration requires two or more pH buffers. A buffer is a solution of known pH which is used as a standard to ensure the electrode is producing accurate results. The most commonly used buffers are pH 7.0, 4.0 and 10.0. Some pH meters will require two buffers for calibration whilst others require three or more. If you are using only two buffers then you will begin your calibration with the pH 7.0 solution and then use either pH 4.0 or pH 10.0 as your second buffer, depending on whether your sample is acidic or alkaline respectively.

The instructions provided with your meter will detail the calibration process. In general, this will involve dipping your electrode into a buffer and waiting for the reading to stabilise. You will then adjust the pH meter to read the correct pH on the display or, if your meter features automatic calibration, it will automatically adjust itself. This process is repeated with the following buffer(s) until the process is complete and the meter is ready to use. Always remember to rinse your electrode in distilled water between different buffer types and make sure to read your manual carefully before calibrating the meter for the first time.

Buffer solutions are available to purchase in 500ml bottles or as packs of 20ml sachets. Sachets are ideal for infrequent use or for use in the field.

How do I clean my pH electrode?

227513Cleaning your electrode will ensure that it stays in optimum condition and will help to maintain accuracy and efficiency. To use a cleaning solution simply place your electrode in it for 15 to 20 minutes then rinse with distilled water and store as recommended below. For pH meters which are designed for use in soil, a cleaning solution for soil deposits is available which will help to eliminate all impurities and residues which are left on the electrode after use.

How do I store my pH electrode when not in use?

180243When your pH meter is not in use the electrode should be kept immersed in storage solution. This stops the electrode from drying out and keeps it clean and protected until required again. Most pH meters come with either a specially designed cap, into which a small amount of storage solution can be added, or they come with a storage bottle which can be topped up with solution. Make sure to check the level of the storage solution regularly as it will evaporate over time. If the electrode is allowed to dry out then it will no longer function correctly and will have to be replaced.

Made by NHBS – The Ichthyoplankton Net

These bespoke nets, made by NHBS, are being used by ZSL in an ongoing project to monitor juvenile and larval fish populations in the Thames.
The Ichthyoplankton Net

Earlier this year we were contacted by the Zoological Society of London (ZSL) who were interested in working with us to make a bespoke aquatic survey net.

Their specifications required the net to have a square frame with a four point bridle and connections for a flow meter. It also needed to have a diving vane which would ensure that it could be towed stably at a set depth, and a screw on cod end with a bag made from 53µm and 250µm mesh. Following these guidelines, our engineer and seamstress got to work and within a couple of weeks a detailed specification was agreed. The nets were then manufactured and two were sent to ZSL in February.

First draft of the net design

Several months later we were delighted to receive some photos from Anna Cucknell, who manages ZSL’s work on fish conservation in the Thames, showing the nets in use.

 

 

“It was great to work with NHBS, who listened to our specific needs to design bespoke sampling nets for juvenile fish, and used their experience to adapt our designs to fit our needs. Our juvenile fish surveys on the Thames are the first of their kind, in scale and resolution and we hope the results from which will be applicable in the Thames and further afield to help drive conservation and better management of our estuaries for all fish species”.
Anna Cucknell, Thames Project Manager, Zoological Society of London

Ichthyoplankton Net in the Thames
Nets are towed both at the surface and at a depth of two metres. Combined with data from seine and intertidal nets, these surveys provide a comprehensive picture of larval and juvenile fish populations.
Fish Conservation in the Thames

The nets we made for ZSL are being used for an ongoing project to monitor the use of the Thames by juvenile fish.

The Tidal Thames is home to more than 100 fish species including many that are commercially important such as Dover sole and European seabass. It also provides critically important habitat for rarer species, including European smelt and European eel.

Like most estuaries, the Thames provides invaluable spawning, migratory and nursery grounds but, despite this, the region is poorly studied. The ZSL project hopes to remedy this by providing essential information about the health of fish populations in the estuary, and to assess how these are affected by water quality and local developments.

Boat-based sampling for juvenile fish

The project, funded by Tideway, involves both boat-based and foreshore sampling and, excitingly, also provides an opportunity for volunteers to get involved via its citizen science scheme. Volunteers can help with a variety of tasks including measuring, identifying and counting the fish.
