Description
Several relationships between the fecundity and the weight or the size of females have been studied for three different (based on "eye-index") stages of incubation. The relationship between the average weight of eggs at the beginning of incubation and the size of the females shows that the egg size varies according to the female's size. Loss of eggs during incubation has been studied ; the average loss between the two extreme stages of incubation is around 27%. This is a lowered value of what accurs during the whole incubation period. Egg losses are greater for small females than for big females. The annual frequency of spawning and size at first maturity have been determined in for differents fishing effort than by the commercial size.
