要約

The influence of temperature fluctuations and dissolved oxygen content on embryonic and early postembryonic development of carp has been investigated. It was found that the atypical increase of water temperature over the spawning period and decrease the dissolved oxygen content negatively affect vitality of embryos. These conditions cause delay of the embryonic stages, change the weight and size of larvae, affect activity of key enzymes, at this energy metabolism partially switches from aerobic to anaerobic. Growth of water temperature decreases the activity of proteases, which directly affect the embryo's organogenesis.
