BEROIS, Nibia; AREZO, María J  and  PAPA, Nicolás G. Gamete interactions in teleost fish: the egg envelope. Basic studies and perspectives as environmental biomonitor. Biol. Res. [online]. 2011, vol.44, n.2, pp.119-124. ISSN 0716-9760.

The current knowledge about teleost fish egg envelope is summarized. The paper analyzes the organization and deposition process of the protein composition and genes involved in the synthesis of teleost fish egg envelopes and their role in gamete interaction during fertilization. Pelagic and demersal species that our research group is working with are especially considered. The vertebrate ZP family of proteins, the evolution and relationship among the different genes and their expression are taken into account. We consider fish envelope as a possible biomonitor for ecological contaminants. The biotechnological applications for aquaculture and genomic and post-genomic approaches are auspicious.

Keywords : fish egg envelope; ZP genes.
