投喂饲料是水产养殖中的一大关键环节,部分养殖户由于不懂饲料的科学使用与管理技术,不能识别鱼类的饥饱,不讲究投喂方法,导致单产低、病害多,经济效益差。所以,水产养殖过程中必须重视饲料的科学使用与管理技术。1.科学投喂饲料春季水温低,鱼体小,食量少,在晴天气温升高时,可投放适量的精饲料。当气温达15℃以上时,投饲量可逐渐增加,每天投喂量可占鱼体总重量的1%左右。夏初水温升至20℃左右时,每天投喂量
Feeding feed is a key link in aquaculture. Some farmers do not know the fishes and hungry due to their ignorance of the scientific use and management techniques of feed, and do not pay attention to the feeding method, resulting in low yields, more diseases and economic benefits difference. Therefore, the aquaculture process must pay attention to the scientific use of feed and management techniques. 1. Scientific Feeding Feeds Spring low water temperature, small fish, less food, in sunny weather when the temperature can be put on the right amount of concentrate feed. When the temperature reaches above 15 ℃, the amount of feeding can be gradually increased, the amount fed per day can account for about 1% of the total weight of the fish. Early summer when the water temperature rose to about 20 ℃, fed ration
