LENGTH FREQUENCY ANALYSIS OF PLEURAGRAMMA ANTARCTICUM,ELECTRONA ANTARCTICA,PROTOMYCTOPHUM BOLINI

British Antarctic Survey(BAS)data collected near the Antarctic Peninsula area were used in this1988/1989 study on the length frequency of three Antarctic fish species(Pleuragramma antarcticum,Electrona antarctica and Protomyctophum bolini)showing that the standard length(SL)of P.Antarcticumranged from 26.0 mm to 161.0 mm,that the 26.0 mm to 54.0 mm SL juveniles could be considered tobe the age group 1 fish,and that the SL of E.antarctica ranged from 39.4 mm to 89.7 mm for themales and 48.0 mm to 118.0 mm for the females,which may contain at least 6 age groups.This ismore than previously thought.P.Bolini had 29.2 mm to 60.2 mm SL and complicated age com-position.
