Gonadosomatic index by length and maturity stage for female arrowtooth flounder (A) and for male 
arrowtooth flounder (B). 
(unpaired £-test; df=27, P<0.001); the increase began 
between 30 and 35 cm in length (Fig. 5B). 
According to histological analysis, L 50 for females 
occurred at 46.9 cm (df=174, F= 897, r 2 =0.76, Fig. 6A) 
and at 42.2 cm (df=56, F=69, r 2 =0.60, Fig. 6B) for males. 
According to macroscopic staging, L 50 for females oc- 
curred at 49.9 cm (df=172, F=748, ^=0.76, Fig. 6A). 
Total fecundity 
In general, the eyed-side ovary lobes were heavier 
than the blind-side lobes (paired £-test; df=154, 
t= 2.663, P=0.009). Linear regression analysis 
(df=153, F= 2365, P<0.001, r 2 =0.94) described the 
relation between the weight of ovarian lobes as
