The article contains data on ultrastructural and morphological changes of loach Misgurnus fossilis L. embryos in early stages of development and larval development on the first days of incubation environment, whicn contain sodium hypochlorite solution. It was established, that sodium hypochlorite is not toxic, because it does not lead to 100% of the larvae death, but lead to inhibition viability and changes of loach larvae morpho-functional characteristics. Determined that sodium hypochlorite lead to considerable ultrastuctural changes of loach embrional cells. Sodium hypochlorite cause damage of plasma membrane integrity and intracellular organelles membrane, cause violation of proteins functional properties and lipids, which further lead to pronounced morphological changes in loach larvae.

Keywords: loach embryos, embryogenesis, sodium hypochlorite
