Aspects of the life history of the Atlantic poacher, Leptagonus decagonus, in Svalbard waters
Abstract The aim of the study is to describe aspects of the life history of the Atlantic poacher (Leptagonus decagonus) obtained during early October 2010 and late September 2011 from the Hinlopen Strait, located between Nordaustlandet and the Spitsbergen Archipelago. Length was measured for 142 ind...
