Abstract

Trawl surveys conducted between 1996 and 2007 show that populations of octopods have significantly higher abundances around Elephant Island, off the Antarctic Peninsula, than in similar areas nearby. This elevated abundance was first detected following the cessation of commercial fishing and has persisted for many years beyond, possibly indicating an enduring shift in the structure of the ecosystem.
