drated oocyte remnants, and no ovaries with POFs 
were found during May (n=306). Hydrated oocyte 
remnants (in two ovaries) and POFs (in one ovary) 
were found in June (n = 180) and July (rc=159). 
Length and age at first 
spawning, and depth of spawning 
Length at first spawning (see “Methods” section for 
definition) was 710 mm TL in 1991, 570 mm TL in 
1993, and 670 mm TL in 1994 for females, and 980 
mm TL for males in 1994. Age at first spawning was 
3 years for females and 7 years for males. Stage-4 
females were caught at depths of 30 m and greater. 
All males were caught at depths greater than 41m. 
Batch fecundity 
Batch fecundity estimates (n=39) ranged from 10,864 
to 865,295 hydrated oocytes (Fig. 5). These estimates 
came from gag 690-1065 mm TL, 4.5-16.5 kg TW, 
23.4-871.9 g ovary weight, and 3-9 years of age. 
Regression analysis showed significant positive 
linear correlations between batch fecundity estimates
