要約

Effects of nucleic acids on viability of embryos and larvae of Misgurnus fossilis, Cyphnus carpio, Ctenopharingodon idella and Hypophtalmichthys molitrix were studied. It was demonstrated that nucleic acids at the concentration of 0.5 mg/L stimulated fish larvae viability and thermal resistance, and at the concentrations of 5.0 mg/L, and especially 50.0 mg/L, they repressed fish embryos and larvae viability, development and growth.
