Table 5. — Length-frequency distributions of white-spotted 

 winter flounder of the 1959 year class obtained from 

 commercial catches in 1964-66 from eastern Georges Bank. 



(Berry et al., 1965; Poole, 1966; Kennedy and 

 Steele, 1971), it does not approach the rate on 

 Georges Bank at any inshore location where it 

 has been described. Growth of females was 

 greater than males after the first few years in 

 all areas, except off Newfoundland where there 

 appeared to be no difference in the age range 

 covered (Figure 6). 



Calculated growth to the first annulus was 

 about 7 or 8 cm for both sexes on Georges 

 Bank (Tables 3 and 4). Although no 0-group 

 fish were obtained from Georges Bank for 

 length comparison, this size agrees closely with 

 the lengths of 0-group winter flounder from 

 inshore Massachusetts waters (Lux and Nichy, 

 1971). There the 0-group fish by late fall 

 averaged 8.7 cm long in 1961 and 7.3 cm in 

 1962. There was no apparent growth difference 

 with sex in these inshore fish, for in late 

 October 1962 the males were 7.3 cm long (n =
