Figure 5 
Histological sample from May 1993 showing some oocytes that had developed into the yolk 
vesicle stage. Note the circumnuclear distribution of the oil droplets that are beginning to 
form, (c = chorion, p = primary oocytes at chromatin nucleolar stage, rf = nondeveloping re- 
serve fund oocytes at perinucleolar stage, v = vesicle ring around nucleus of yolk vesicle stage 
oocyte). 
Table 4 
Estimated total numbers of female fish, numbers of female fish in sampled strata, percentage of female fish in strata covered by 
sampling, numbers of prespawners, proportion of prespawners with standard error (SE), for each age class in the May surveys 
(NA indicates that the value could not be estimated). SE = standard error.
