Algunos aspectos del desarrollo inicial del ovario de sardina (Sardina pilchardus Walb.)

Abstract

[EN] In this paper are reported some histological observations on ovaria of litle sardinas from 14 mm to 120 mm of total length. The authors have determined the first length at witch the sexual glands became outlined within the celoma (37 mm) and when sexual diferentiation take place (45 mm). In sardines of 100 mm the ovaria is completely organized. In the first increased stage of ovaria we have observed numerous transition cells that are interpreted as evolution forms from epithelial cells to sexual cells

[ES] Este trabajo es el primero de una serie en que hemos abordado varios aspectos histológicos del ovario de sardina con vistas a una más perfecta interpretación de sus cambios morfofisiológicos desde la aparición de los esbozos del mismo hasta su completa maduración sexual, [...]
