After the beginning of autumn, the temperature of the water began to decline, and fish eaten gradually. This is also the golden period for the growth of fish production. Therefore, the autumn management of the adult fish pond is also the key to high yield.
First, strengthen feeding feeding.
At this time, the feed should be concentrated on concentrates, and the emphasis should be placed on the bottom-feeding fish for fattening and fattening. At the same time should pay attention to the rough feed mix to ensure that fish feed nutrition is fully comprehensive. Grass carp should be properly fed grass grass, green carp should be cast screw material, carp should also be appropriate fertilization, after the beginning of autumn fertilization should be less amount of ground facilities, and mainly inorganic fertilizer, but also according to the situation of the fish, water, fertilizer Degree, weather, etc.
Second, a reasonable adjustment of water quality (1) plus new water, usually add 4 to 5 times a month, each time 1 to 2 hours, water 5 to 10%.
(2) splash lime, quicklime can neutralize hydrogen ions, increase calcium, increase water body fat, at the same time can be sterilized, prevent disease. Usually every half month, each time 20-25 kilograms per mu.
Third, timely arrest, pay attention to daily management.
After the beginning of autumn, some fish have reached the specifications of commodities. If they continue to feed, eat a large amount, and grow slowly, they should start catching and listing in time to reduce the density of fish pools and accelerate the growth of fish that do not meet specifications. Through long-term accumulation, more and more organic matter is deposited on the bottom of the pool. In case of weather changes, it will lead to pan-pooling. At this time, we must strengthen daily management and focus on observing fish activity.
Fourth, the prevention and treatment of fish diseases. After the beginning of autumn, the fish is susceptible to rot and complications of enteritis. According to the author's practice of using rapeseed oil and ginger mixture to treat the complications of grass carp gill and enteritis, the curative effect is significant. The formula of this medicine is described as follows:
(1) Medication quantity: 750g vegetable oil and 250g ginger per 667m2 pond.
(2) Medication method: Put the vegetable oil into the pan and cook it. Then pour the ginger into the pan for 20 minutes, remove it and put it into the bucket. Rinse the appropriate amount of water and stir it. When it is fully mixed, it can be sprinkled all over the pool, especially near the food table frame.
(3) The number of medications: 1 daily medication, or every other day, with 2 splashes. When using, three things should be noticed: that is, splashing should be uniform; choose sunny operation; change the water after 5 days after splashing (especially hot weather, special diligently change the water).
