Length-ovary-weight relationship for arrowtooth flounder (Atheresthes 

 storriias). 



Results 



The length-somatic-weight and length-ovary-weight data 

 for arrowtooth flounder (Figs. 1 and 2) and darkblotched 

 rockfish (Figs. 3 and 4) both conformed to allometric rela- 

 tionships. Length-somatic-weight data for both species 

 conformed closely to the model fitted to them (r'^=0.90- 

 0.98, Table 1). The data for the length-ovary-weight 

 relationship conformed to the fitted line reasonably well 



for arrowtooth flounder ir^=0.85) and only moderately 

 well for darkblotched rockfish (r^=0.65). Although sample 

 sizes for ovary weight data were low for both species 

 (?! = 19-28), the histological classifications available for 

 arrowtooth flounder helped to assure that all fish collected 

 were fully mature and to minimize the scatter about the 

 length-ovary-weight relationship. The scatter about the 

 length-GSl relationships for both species (Figs. 5 and 6) 

 was relatively high (r-=0.32 for arrowtooth and 0.36 for
