Resumo: 	The size and age at sexual maturity of the lobsters was determined by secondary sexual characteristics (1) morphological criteria such as length of P1 protopodite, size of the abdomen, and the presence or absence of ovarian hairs in the female; and (2) functional criteria such as the presence of spermatophores in the female and development of the ovaries. A study of fecundity was carried out after maturation of the ovaries and at the end of incubation. The number of eggs lost during incubation was estimated at 45%. The contribution of different age classes to the global fecundity of the stock was simulated on a model of fecundity by recruits.
