Distribution, growth, diet and foraging behaviour of the yellow-fin notothen Patagonotothen guntheri (Norman)on the Shag Rocks shelf (Southern Ocean)
The distribution, total length (L-T) frequency and diet of Patagonotothen guntheri are described from 14 bottom trawl surveys conducted on the Shag Rocks and South Georgia shelves in the austral summers from 1986 to 2006. Patagonotothen guntheri (80-265 mm L-T) were caught on the Shag Rocks shelf fr...
