Summer Pond Fish Management Technology

Inspect the floating heads thoroughly to ensure that the floating heads are inspected three times a day in the morning, in the middle of the evening, and in the evening. In the morning, observe whether there are floating head fish and floating heads in the pond. At noon check the fish's food and water, and determine if the amount of feed and the amount of fertilizer are appropriate. In the evening, check whether there is residual feed and whether there is any signs of floating heads. Immediately increase the oxygen level when floating heads have occurred.

Pay attention to adjusting the water quality In addition to the correct fertilization and feeding, the ponds with stronger water color should be frequently filled with fresh water to keep the water fresh. Generally, fresh water is added every 7-10 days, and water is added 15-20 centimeters each time. Frequent inspection and maintenance into the drainage ditch to keep the water fluent. In the rainstorm season, check and prevent flooding and fish escape. In the season of farmland medication, close attention should be paid to the use of pesticides in the surrounding farmland to understand where the farmland drains, and to prevent the discharge of pesticide-laden water into fish ponds.

Strengthening feed for feed requires fresh and palatable. When feeding, we adhere to the principle of "Four Sets" and plan to feed various feeds and feed them twice a day. The feed is finished within half an hour, and the feed requires nutrition to be comprehensive and adequate. In the case of low transparency or rainy days, reduce the amount of feeding. Little or no feed before and after rainfall. Daily overnight residual feed and leftover grass should be removed to avoid polluting the water.

Rational fertilization and fertilization follow a small number of principles, observe the water color, and control the amount of topdressing according to the water's fatness. Generally, the transparency of the water body should be about 30 cm, and the water color should be tea brown. From June to September, 5-6 kilograms of bio-organic fertilizer can be applied per mu, 3-4 times per month.

Doing preventive work well before the epidemic season of fish disease is one of the important measures to prevent the occurrence of fish disease. Specific method: 1 meter per mu water surface per month with quick lime 15-20 kg of slurry after spilling once, every half a meter water depth of 1 meter with strong chlorine 100-200 grams and per cubic meter of water 0.5 grams of 90% crystal trichlorfon alternately Quanchiposa. At the same time every month at the feed station for bleaching powder and copper sulphate, ferrous sulfate mixture bag sterilization. Can be used to prevent the use of drugs added to the feed made bait, with good results. During the epidemic of fish diseases, fishery tools such as nets and barrels should be disinfected to avoid mutual infection.
