INFLUENCE OF TEMPERATURE AND OXYGEN REGIME OF WATER ENVIRONMENT ON THE SURVIVAL AND DEVELOPMENT OF CARP FISH
Abstract
The effect of fluctuations in temperature and dissolved oxygen in natural waters in the passage of the embryonic development of carp, grass carp and carp. It found that at higher water temperatures atypical and reducing the dissolved oxygen is substantially reduced viability of fish embryos. These conditions are easily stay ut potent teratogens, causing delay passage of the embryonic stages of development, changing the mass-dimensional characteristics of the larvae and are the cause of the abnormally developed individuals.
Keywords: silver carp, grass carp, carp, embryonic development, water temperature, dissolved oxygen, teratogens, abnormal development of the larvae.
