November has entered the late autumn and early winter, and the temperature and water temperature continue to decrease. The harvest season for fishery production has also come. At the same time, tropical fish and shrimp should be accelerated into the wintering and conservation period, and conventional fish seedlings and broodstock should also be prepared to overwinter and pond winter, and strengthen management. Large water surface winter catch will be fully spread.
First, the pond fish cultivation should be prepared for the various preparations.
With the decrease of water temperature, the ingestion intensity of fish is also greatly reduced, and it is possible to prepare for fishing nets, transportation tools, and markets. Conventional fish such as cockroaches, clams, grasses, blues, oysters, and squid should be caught timely. Get up to date.
Second, regular fish species should be used to pull nets and wintering ponds.
It is not too early for the conventional fish seedlings to plant winter ponds. It is generally appropriate to have the water temperature around 10°C, but it should not be lower than 8°C. Before the winter, you must pull the net to exercise 1 or 2 times, and then pond. Pull the net to be light to avoid fish injuries, infect various skin diseases in the lower pool and cause dead fish.
General conditions of the pond, each mu of water can be stocked specifications of 10 to 12 cm of 2 to 30,000 fish species.
Third, prepare the winter of broodstock.
Routine species of broodstock, we must pay close attention to the clear pond, and actively prepare for the winter. In November, when the water temperature is reduced to about 10°C, the average pond can be stocked for winter at a density of 150-200 kg per acre, and after entering the wintering pond, a small amount of fertilization is required for the earthworms and carp ponds. When the water temperature is high at noon on sunny days , can feed some concentrate feed properly. Grass carp, herring, carp, squid and other pro-fish ponds should also pay attention to feeding concentrate feed, when the water temperature is high, a small amount can be fed at noon every day, when the water temperature is low, 2 to 3 days can be fed once.
Fourth, tropical fish species must seize the time into the wintering pool.
Tropical fish species must seize the time to enter the wintering pool. Tilapia should enter the wintering pool when the water temperature drops to 15 to 16°C. The density of each mu of water surface, the size of 25 ~ 40 tail / kg of fish 1.5 ~ 20,000.
Fifth, large water surface to be fully fishing.
You can use catch, barrage, thorn, and joint fishing methods to catch large water surfaces such as reservoirs and lakes. In combination with the winter fishing season, various broodstock for artificial propagation can be selected.
Sixth, the fish should be cleared in advance in the clear pond, disinfection.
In some places, after the autumn harvest, fish species are ready to be released. Fish must be thoroughly cleared and poisoned before the fish can be released. The fish species must also be strictly disinfected.
