1, fish farming
In areas with abundant insect resources, several black light lamps can be installed on the surface of fish ponds. Each lamp can induce 5-6 kg of insects like mosquitoes, flies and roundworms to be eaten by fish every night. Or hang a few porcelain boxes on the surface of the pond, and use animal scraps to attract and raise the fly. A large number of worms climb out of the box and fall into the water to become bait. Artificial feeding of crickets, yellow mealworms, etc. can also be adopted to feed fish. Generally 2 kg of insects can grow 1 kg of fish.
2. Fish farming
Fish fish farming refers to the method of rational polyculture and recycling fish feed. In general, fish, carp, grass carp, carp, carp, squid and other filter foods, herbivorous, carnivorous fish rational polyculture can make full use of the nutrition of different water layers. The excrement of fish can be used as fertilizer and water. The plankton that reproduces can feed babbles and earthworms. The residue of food can provide bait for alfalfa and cockroaches. Dead fish and wild fish can also provide baits for cod and other fish. It is worth noting that it is necessary to distinguish between the ratio of the main fish and the set of fish.
3, species of blue fish
Use forage grass and green feed to raise herbivorous fish. It can be planted in the grasshopper or feed field using Sudan grass and ryegrass rotation method. Generally, Sudan grass is 667 square meters (mu) and 11000-12500 kg, and rye grass is 667 square meters, producing 7000-9000 kg. Hey. An average of 1 kilogram of fish per 25 kilograms of grass, and the fish eat high-quality green feed is not easy to get sick, can save fish disease diagnosis and treatment costs.
4, fish and poultry polyculture
Poultry manure is rich in protein, minerals, and some vitamins. Feeding fish can also save a lot of feed. The method for polyculture of fish and poultry is to feed and grass in the pool, attach a chicken house or duck canopy, feed chickens and ducks with feed and grass (also feed fish after processing), chicken and duck manure to feed fish and water, and pond mud. The feces of 50 chickens and 40 ducks can feed 667 square meters of fish.
5, self-made feed (can be mixed with aquatic feed)
Fish farming has a wide range of feed sources in rural areas. It can properly process vegetable feeds, agricultural and sideline products, and animal feeds into mixed feeds. Local materials can save on feed costs and are nutritious. General reference can be made to the composition of the following artificial feeds: about 30% of animal protein components (such as fish meal, blood meal, cocoon, liver scum, etc.), about 30% of bean residue (bean curd residue, powder residue), and 30% of wheat bran, etc. Guzi 5%, plus 1% vegetable oil, 1% lotus root powder, 1% bone meal, 0.1% vitamin, etc., can also add 1 kg salt per 100 kg of feed when adjusting the feed, which can not only improve the quality of feed , but also sterilization and disease prevention.
6, cast fertilizer fish (mainly fertilizer fish)
In front of the fish ponds, the basal fertilizer can be deeply applied to fertilize the water quality. Generally, 200-300 kg of decomposed livestock manure or about 100 kg of human waste is used per 667 m 2 of the pond; the pond should be properly treated according to water quality, weather, and fish growth conditions. Topdressing, generally 50-70 kg of fermented manure is applied every 667 square meters, and the whole pool is splashed. In addition, it is also possible to feed 1% of the total weight of the fish in the hot season. Applying top dressing can also use inorganic fertilizers. Generally, 1.5 kg of ammonium sulfate and 0.25 kg of superphosphate are applied every 2-3 days.
