要約

It is shown experimentally that viability of fish embryos depends on the CO2 concentrations in aquatic medium at the period of fecundation and swelling of eggs. CO2 concentrations of 8-9 mg/L stimulated vitality of larvae of phytophilous fishes. Proceeding from the results obtained, the authors recommend the standards of CO2 concentrations at various dimensional stages of fish (in particular, white amur, white bullhead, bream) breeding in ponds.
