First approach to the study of atresia in the ovary of sardine, Sardina pilchardus (Walb.)
The ovary atresia characteristics of sardine, Sardina pilchardus, on the Iberian Peninsula were described using the same nomenclature and criteria adopted for the northern anchovy, Engraulis mordax J., by Hunter and Maceuncz (1985a). The data used were based on sardine biological information obtaine...

| Resumo: | The ovary atresia characteristics of sardine, Sardina pilchardus, on the Iberian Peninsula were described using the same nomenclature and criteria adopted for the northern anchovy, Engraulis mordax J., by Hunter and Maceuncz (1985a). The data used were based on sardine biological information obtained from laboratory experiments and Daily Egg Production Method (DEPM) survey samples. In the laboratory, the occurrence of atresia was low, and most atresia stages corresponded to a-stage. An increase in the number of females in more advanced degeneration stages was noted as starvation time increased. In the natural population, atresia stages mostly appeared after the complete degeneration or postovulatory follicles. The complete yolked oocyte atresia process took no more than 6 days. |
