Abstract:
Under low temperature of winter season,wintering fishes can absorb nourishment from intestinal contents(organic pieces,algae,water plants,silts).The saturation and composition of intestinal contents change with different types of water and fishes.The saturation in the intestine is increased gradually from front intestine,and the latter part of it has the highest saturation and can reach fourth degree.The research result showed that feeding wintering fishes could insure and increase survival rate and growth.
Key words:
