摘要: Abstract Oocytes and eggs from teleost fishes are always surrounded by an egg envelope of variable dimensions. This (zona radiata) in teleosts normally consists two layers, a zona radiata interna externa. The chemical composition the is proteinaceous. Neutral acid mucopolysaccha‐rides main components largely responsible for protective function, whereas externa used to attach substrate where they deposited. For latter it equipped with mechanisms such as special sticky layers (e.g., Phoxinus pboxinus, Chalcalburnus chalcoides mento, Esox sp., Lota lota 1‐eggs cichlids), hexagonal patterns many percids channichthyids), villi‐like protuberances (= attaching‐plugs; cyprinids), attaching‐filaments gobies blennies, p‐eggs cichlids, piranhas clariids), jelly layer (Perca fluviatilis) or muco‐follicle ...
