RECRUITMENT AND BODY SIZE IN RELATION TO TEMPERATURE IN JUVENILE PATAGONIAN TOOTHFISH (DISSOSTICHUS ELEGINOIDES) AT SOUTH GEORGIA
commercially important, deepwater nototheniid fish, was examined at the sub-Antarctic island of South Georgia ... . Abundance of the 1+ juvenile fish cohort (13 to 15 month old dependent on survey date) was found to vary ... and larvae were not significantly correlated with juvenile density. The mean length of 1+ fish ... attained after 13-15 months was higher in years of high juvenile abundance and was significantly inversely ...
