Physical and behavioural influences on larval fish retention: contrasting patterns in two Antarctic fishes
Abstract: Waters around South Georgia are amongst the most productive in the Southern Ocean, and ... retention of the planktonic stages (eggs and larvae) of marine fish can play a key role in the maintenance ... of adult stocks. Here we use a numerical modelling approach to examine the influence of oceanographic ... and life history variability on the dispersal and retention of two species of Antarctic fish ...
