Life history studies evaluated 



Aging, length frequency, sex ratio and maturity, survival, 

 movements and exploitation 



All adults measured and sexed from 1983 through 1986. The 

 von Bertalanffy growth model applied to data. 



1984 



Length frequency, sex ratio and maturity, movements and 

 exploitation 



Adult life history studies decreased in favor of increased 

 larval and juvenile work. 



1985 Length frequency, sex ratio and maturity 



1986 I ength frequency, .sex ratio and maturity 



estimated from length -frequencies and a length-fecundity relationship determined from 1977 data using a 

 functional regression model with log-transformed vaxiables (Jolicoeur 1975; Sprent and Dolby 1980). 

 Forty-eight fish from 24.5 to 43.3 cm were examined according to methods found in NUSCo (1978a).
