Alan Jamieson: The deepest of them all: In situ observations of the world’s deepest fishes



Alan Jamieson, Newcastle University, gave a lecture titled “The deepest of them all: In situ observations of the world’s deepest fishes” at FishBase Symposium 2018 in Stockholm, Sweden, on 15th October, 2018.

ABSTRACT: A little over 10 years ago there were no recorded images or video of fish in the hadal zone (depths exceeding 6000 metres). While we knew much about abyssal fishes, records of hadal fish were largely a collection of individual, often badly damaged, samples with often dubious depths of capture. Since 2007 over 200 deployments of baited traps and cameras have returned a wealth of new in situ observations of both lower abyssal and hadal fishes from the subduction trenches around the Pacific Rim. The research campaigns have also recovered many specimens which have proven why teleosts are limited to ~8200m and other insights in their life history, feeding habits and behaviour. This talk focus on the families Macrouridae (rat-tails), Ophidiidae (Cusk eels) and the deepest of them all, the Liparidae (snailfish).
