Abstract:The main aim of our experiments was to study the influence of colored light on juveniles of Carassius carassius, Perccottus glenii and Poecilia reticulata. The species of fish used for studies differ in their biotopes and feeding behavior. The results of experiments demonstrated that different species of fish can have different response to light quality. Thus crucian carp developed better by green light, rotan-by blue and green, guppy - by blue light. By red light the growth rate in all species decreased. The response in different species of fish to the light environment appears to be governed by changes in energy metabolism and hormone disproportionation.
