INTRAOVARIAN SPERM STORAGE IN HELICOLENUS DACTYLOPTERUS DACTYLOPTERUS: FERTILIZATION, CRYPT FORMATION AND MAINTENANCE OF STORED SPERM

摘要: The females of the bluemouth rockfish, Helicolenus dactylopterus (DelaRoche, 1809), store sperm within their ovaries for periods up to 10 months. Twenty six with standard lengths between 152 and 257 mm males 253 290 were caught this study during course a year. They analysed in order observe ultrastructure storage crypts stored spermatozoa describe evolution over After internal fertilization once reaches ovary, crypt forms probably by an epithelial inclusion at base lamellae one or several groups that are floating freely interlamellar space ovarian lumen. Stored have large cytoplasm bag surrounding heads. This could serve as nutritive reservoir long period. Many desmosomal tight junctions cells ensure male sex protected against female immune system.
