Figure 8. — Mean length (cm) and mean age (yearsi of witch flounder per depth interval in Div. 2J, 3K, 

 and 3L separately and combined from research vessel surveys during 1977-83. (Number in brackets 

 refers to the number offish observed.) 



1979-83 in Div. 3L, males and females ranged 

 from 3 to 13 years old and 3 to 17 years old respec- 

 tively. Only about 57( of the males were older 

 than 11 years and about 8V( of the females were 

 older than 12 years. 



Growth Curves 



Growth curves of male and female witch floun- 

 der with mean lengths at age are presented in 

 Figure 11 and Table 1. Clearly, males do not grow 

 as fast as females over the life span. Growth rates
