Heavy rainstorms are not necessarily beneficial to aquaculture

Chang Chuanfen, deputy director of the Wujin District Aquatic Technology Guidance Station in Changzhou City, said that in light of the current state of cultivation, heavy rainfall will suddenly change the environment of the pond water. The intense erosion of rain will accelerate the flow of surface water and bottom water in the pond water. The nitrites and other harmful substances in the bottom of the pool will float, and the dissolved oxygen content in the water will decrease, causing greater stress on the fish and causing flooding. Vitamin C, allicin, etc. can be added to the aquatic feed in advance to improve the immunity of the fish and reduce the heavy rainfall stress. In addition, after heavy rainfall, the water body is relatively turbid, and 2 kilograms of alum can be used to purify the water quality per acre per meter of water depth. After the rain, the farmers should take corresponding measures according to the different cultured objects. The ponds of farming squid, squid and squid should be dominated by fertilizer and water, and the ponds of cultivating shrimps and crabs should be mainly improved in transparency, and the aerators should be opened at a proper time. oxygen.
