A novel method for rapid elimination of sturgeon egg stickiness using sodium hypochlorite

Original language description

Reducing egg stickiness is a crucial step in artificial culture of sturgeon eggs, with commonly used methods being time consuming or interfering with hatching. Sodium hypochlorite (SH) at varying concentrations and exposure times was tested on sterlet Acipenser ruthenus eggs, with 0.03% SH for 40 s effectively eliminating stickiness without impairment to eggs, embryo development, or hatching when compared with other de-adhesion methods (clay; NaCl, urea, and tannic acid). Field tests using sterlet, Siberian sturgeon Acipenser baerii, and Russian sturgeon Acipenser gueldenstaedtii showed similar numbers of larvae hatched using SH and clay. Immunohistochemistry revealed a protein carbonyl group only on the surface of eggs treated with SH, evidence of oxidation as the mode of action and indicating that oxidation did not affect inner egg layers or cytoplasm. Treatment with SH is a rapid, simple, and inexpensive method for de-adhesion of sturgeon eggs. Statement of relevance: Sturgeons represent a valuable group of fish in aquaculture, especially for caviar, but also for meat production. This study describes a novel approach to sturgeon egg de-adhesion involving oxidation of egg surface. The method requires little time, is low cost, and disinfects and softens the egg surface, which facilitates hatching.
