Sharks under increased threat from fisheries

New research indicates that shark species may be under greater threat from human activity than previously thought. Results just published in Proceedings of the Royal Society by Professor Monty Priede, Director of Aberdeen University’s Oceanlab, suggest that sharks haven’t adapted to depths of more than 3,000 metres – making them absent from over 70% of the world’s oceans, and, crucially, mostly present at depths within the reach of human fisheries. This research raises the interesting question of why there are no really deep water species of shark when many species of bony fish are adapted to far deeper waters.

News of this research has been reported widely: see e.g. Guardian and BBC coverage.

Sharks, Rays and Chimaeras: The Status of the Chondrichthyan Fishes and the forthcoming Sharks of the World: An Annotated and Illustrated Catalogue of Shark Species Known to Date, Volume 1 FAO are key references for those interested in the status of shark species from a conservation viewpoint.

For more general information Collins Field Guide: Sharks of the World is hard to beat (see also the previous edition Collins Sharks and Rays) or Shark. Sharks, Skates, and Rays The Biology of Elasmobranch Fishes provides comprehensive coverage on the biology and ecology of sharks.

Dodo: the Bird behind the Legend – review on www.fatbirder.com

Dodo: The Bird behind the LegendDodo: The Bird behind the Legend

It is a sad tale indeed of how man’s selfish use of the world despoiled paradise and led to the Dodo’s demise along with other avian endemics and much more besides. Worse still is the fact that if we could turn back the clock, despite all we have learned, we would probably do it all again so long as humans see the natural world as their resource rather than their companion.

The book has collected together some excellent paintings, sculpture, and even fiction giving breadth to the myths as well as the facts and even speculates as to whether we could re-engineer a dodo from the remaining relatives not too forced into extinction. As sad as the subject matter may be this is a delightfully well written and presented work which I much enjoyed reading and looking at; it deserves a wide audience not just for its message but its intrinsic qualities.
