Autumn show broodstock breeding technology

First, the method of cultivation of grass and blue broodstock
1. Suitable for autumn feeding season, it is the season when grasses and blue broodstock have the most food intake. Throughout the autumn, the feeding principle of “concentrate-based, refined-coarse” should be adopted. Grass carp broodstock feeds about 150 grams of fine material such as wheat and soybean cake every day and feeds green feed once every 2 days. Each feeding amount is about 20% of the body weight of the broodstock. Green broodstock is mainly fed with snails, clams, and oysters, supplemented by bean cakes. Generally, each broodstock needs to be fed with 15 kg to 20 kg of snails, clams, and quail meats during the entire autumnal culture period, and is then fed with 25 kg of bean cake.
2. Adjust the water quality Autumn grasses and blue broodstocks have large food intake and frequent activities. The water quality is prone to aging. In the event of rainy and humid weather, there will be oxygen-depleted floating heads. So always add new water to make the pond fresh. For conditional ponds, aerators should be installed, and oxygen should be turned on when necessary to increase dissolved oxygen in the water, improve water quality, and facilitate the development of gonads in grasses and blue broodstocks.
3. Prevention and treatment of diseases Autumn grass, blue broodstock prone to enteritis, gills, red skin and other diseases. First of all, we must do a good job in prevention work. Disinfect water bodies with quicklime and “strong chlorine”. Followed by not feeding moldy feed, feeding green material should be sterilized with bleach and then fed.
Second, the pheasant, pheasant broodstock method
1. Fertilizer should be regularly applied organic fertilizer in autumn, the main pond to raise squid, organic fertilizer ratio is 70% of human feces and 30% of pig cow dung; the main carp pond, organic fertilizer ratio is 70% Pig cow dung and 30% of manure. The number and number of shots to be cast should be based on the pond's fatness, changes in the weather, and the activity of the broodstock. The general principle is to keep the body of water dark brown with a transparency of about 20 cm. If necessary, add powdered feed for broodstock to accumulate fat and ensure normal development of the gonads.
2. Adjusting water quality In the autumn, the pond should be frequently injected with fresh water. To maintain the fertility and tenderness of the water body, the pond water must be filled in the late autumn.
3. Fish Disease Prevention and control of crickets, crickets broodstock fall susceptible to parasitic diseases, such as anchor head lice and fish carcasses, etc., can be used "fish vermiculite" "Pest exterminator" and other Quanchiposa, can prevent parasitic diseases.
