螃蟹生长发育所需的饵料,除天然饵料外,大部分尚需人工投喂,投喂方法也必须与养鱼一样,做到三看四定,具体地说: 三看:一是看季节,在开春2—3月份,天气较冷,螃蟹摄食少,可选择晴天的傍晚,用少量麦麸、豆饼拌成糊状投放在食台上;清明以后,水温逐渐升高,可投喂小鱼虾、鱼干、菜叶、莴笋叶等,并逐渐增大投饵量;小满到白露,螃蟹食量大,可大量投喂浮萍、苏丹草等,同时搭配投喂动物内脏、蚯蚓、蚌肉等;白露至霜降,水温渐低,此时应加大动物性饵料如螺蚌、蚯蚓、小鱼虾等的投喂量以利体内脂肪积累。二是看天气,晴天多喂,阴天、
Crabs required for the growth and development of food, in addition to natural food, most still need artificial feeding, feeding methods must also be the same with fish, so look at the three set, specifically: Three to see: First, look at the season, In the spring 2-3 months, the weather is colder, less crab feeding, you can choose the sunny evening, with a small amount of wheat bran, soybean meal mix into a paste on the table; Qingming later, the water temperature gradually increased, you can feed small fish Shrimp, dried fish, leaves, lettuce leaves, and gradually increase the amount of feeding; Xiaman to white dew, crab food intake, can be fed a lot of duckweed, Sudan grass, etc., at the same time with animal offal feeding, earthworms, clam meat Etc.; white dew to frost, water temperature is getting lower, this time should be increased animal feed such as snails, earthworms, small fish shrimp feed to facilitate the accumulation of body fat. The second is to see the weather, sunny and more feeding, cloudy,
