Egg stickiness in artificial reproduction of sturgeon: an overview

Popis výsledku v původním jazyce

The egg structure of sturgeon is complex, with multiple micropyles and an envelope structure different from that of teleosts and other fish groups. In the sturgeon, an adhesive layer in the follicular epithelium is responsible for the egg adhesiveness. This is a problem for artificial reproduction of many fish species, including sturgeon, when a large number of eggs are incubated in hatchery conditions. Although several techniques for removing adhesiveness have been developed and successfully applied to eggs of common carp, tench, pikeperch and European catfish, de-sticking methods for sturgeon are limited. Proteolytic enzymes have been successfully applied to common carp, tench and African catfish eggs, leading to a hatching rate over 80% following 2-min treatment. In sturgeon, blue clay is the most commonly used de-sticking substance. The chemical reactions determining egg adhesiveness in sturgeon are poorly studied, and optimum methods for removing stickiness remain to be developed.
