Abstract
Uma melhor compreensão da dinâmica do processo reprodutivo de Sardinella brasiliensis e obtida através da associação de aspectos micro e macroscópicos das gonadas durante o ciclo sexual. O presente trabalho apresenta uma descrição das fases de desenvolvimento ovocitarias e dos estadios de maturidade dos ovarios de 119 fêmeas de S. brasiliensis, coletados na costa brasileira entre 22ºS e 28ºS. São descritas seis fases ovocitarias e duas estruturas derivadas, analisando-se as características citologicas das células germinativas durante o processo de maturação. Foram estabelecidos sete estadios: A (virgem), Bi (em início de maturação), Bf (em maturação avançada), Cf (maduro inicial), Cf (maduro desovado), D (es vaziado) e R (em repouso), sendo discutida sua correspondência com outras es calas aplicadas as espécies.
A better understanding of the reproductive process is obtained when histologic analysis of gonades is associated with macroscopic observations during the sexual cycles. This paper describes the developmental stages of the oocytes of the ovaries in 119 females of S. brasiliensis sampled along the Brazilian coast, between 22ºS and 28ºS. The cytologic characteristics of the germinative cells during the maturation process are given and six oocyte phases are described. Seven maturity stages are established: A (virgin), Bi (incipient maturation), Bf (advanced maturation), Ci (mature), Cf (ripe), D (spent) and R (repose). These stages are compared to those presently used with respect to S. brasiliensis.
