许多渔场养鱼池和水库养殖十几年未清淤,底部的残饵、鱼粪便等有机物污泥厚达1.0～2.5米,使水环境严重恶化,经常发生赤潮和鱼病,因此改善水质,提高淡水养殖知识,越来越受到人们的重视。1、重视对食物的清整和消毒,防止水质恶化每年的4～8月是鱼病的流行季节,尤其是经常投喂饲料养殖的鱼池,往往因剩余残饵没有消除干净,造成水质恶化,病菌繁生,引起池鱼死亡,因此,要重视对食物的清整和消毒,减少鱼病的发生,具体做法是选择适宜的位置,用鱼竿搭成三角架做食物,在三角架各边的中央及角顶悬挂致密的小竹篓数只,篓中装入漂白粉,漂白粉装入篓内要加盖,防止漂白粉浮出篓外。挂篓区如发现鱼不进食场吃食,
Many fish farms and reservoirs in many fisheries have not been dredged for more than ten years. At the bottom of the pond, residual sludge at the bottom and organic waste such as fish droppings reach a thickness of 1.0-2.5 m, which seriously deteriorates the water environment and causes frequent red tide and fish diseases. Therefore, water quality, Increasing knowledge of freshwater aquaculture has drawn more and more attention. 1, pay attention to food cleansing and disinfection, to prevent water quality Every year from April to August is the epidemic season of fish disease, especially often fed feed ponds, often due to the remaining bait did not eliminate clean, resulting in deterioration of water quality, Therefore, we should pay attention to the cleaning and disinfection of food and reduce the occurrence of fish diseases. The specific approach is to choose the appropriate location, make tripods with rods to make food, in the side of the tripod The central and the top of the corner hanging a few small bamboo baskets, baskets into the bleach, bleach into the basket to be stamped to prevent the floating powder floating out of the basket. Hanging basket area such as fish do not find food to eat,
