Oogenesis and spawning in Cardinops sagax, B.C.S., Mexico, and Engraulis encrasicolus, Mediterranean sea
Rosa Isabel Ochoa Báez y Julián René Torres Villegas
Oogenesis in teleost fishes has been described in numerous species based on microscopic morphology, this methodology allows to follow the dynamics during the growth of the oocyte, the spawning and the post in each day in the reproductive season. The information produced provides the parameters to estimate the spawning biomass by the daily method egg production, applied in pelagic fish. The Pacific sardine, Sardiops sagax, from northwestern Mexico and Engraulis encrasicolus, in the Mediterranean Sea, are examples. Both are iteroparous species, characterized by the polymodal distribution of intraovarian oocyte diameter. The objective of this study is to compare the tissue and cellular changes in the ovary during the maturity of the oocytes and the postovulatory follicles in the circadian cycle, during the season of maximum reproductive activity.
Palabras clave: Cardinops saga; Engraulis encrasicolus
