Ten measures to reduce the cost of feed for fish farming
1. Feed the compound feed. Feeding compound feed is an important way to reduce the cost of fish feed. Fish fed with compound feed has good palatability and nutrition, which not only helps to increase the source of feed, reduces the feed coefficient and production cost, but also increases the growth rate and increase the rate of fish, shortens the cycle of fish culture and reduces fish diseases.
2. Choose the right feed formulation. Different fish or the same type of fish have different requirements for nutrients in different growth stages and environments. Therefore, according to the dietary characteristics of the main fish, the individual size, and the age requirements for nutrition, the appropriate feed formulation should be used to meet the nutritional needs of the main fish without wasting feed.
3. Take a scientific feeding method. Pond fish farming should be fed in accordance with the principle of “timed, quantitative, qualitative, and orientationâ€. This can facilitate the observation of fish feeding conditions and reduce feed wastage. Feeding is not enough when you are full of hunger, so that fish eat uneven, affecting digestion and growth. In addition, according to the size of the fish body and the water temperature, several times a day feeding. The smaller the fish size, the more the number of feedings per day; within the appropriate temperature range, the higher the water temperature, the higher the amount of feeding and the number of feedings. In summary, the use of a small number of multiple feeding methods saves the feed more than one feeding.
4. Pay attention to water quality regulation. Good water quality can promote fish growth, improve feed utilization, and reduce feed conversion. Therefore, during the breeding season, especially during the growing season, it is necessary to regularly adjust the water quality by adding new water, splashing lime, and raising the growth machine.
5. Pay attention to the prevention of fish diseases. If fish disease is found in the breeding process, it will affect the feeding of fish. Even if the diseased fish are ingested, the utilization rate of feed is not high and the feed is wasted. Therefore, special attention must be paid to the prevention of fish diseases. The main preventive measures include: thorough cleaning of ponds, killing of various pathogens and wild fish; excavation of excessive silt to prevent the growth of various pathogens; fish stocks should be strictly sterilized, not to allow the fish species to bring bacteria to the pool, and Disinfection of wounds; daily attention should be paid to add new water, and regularly throw lime and disinfectants to disinfect the body of water, regulate water quality; regularly feeding medicinal bait to prevent the occurrence of a variety of harmful fish diseases.
6. Fertilizer fish. Fertilizer fish farming is an effective way to reduce the cost of fish feed. The commonly used chemical fertilizers include urea, ammonium bicarbonate, superphosphate, calcium magnesium phosphate fertilizer, and compound fertilizer. When applying, the principle of less quantity should be mastered. Apply every 3 to 5 days, and apply 2-3 kg of urea or 5 to 10 kg of ammonium bicarbonate and 8 to 10 kg of superphosphate per mu. The application of chemical fertilizers can rapidly increase the amount of plankton in ponds, and has a better effect on earthworms and catfishes.
7. Grass farming fish. Grass cultivation of fish is an effective way to solve fish feed, reduce feed costs, and improve the effectiveness of fish farming. As long as scientific arrangements are made and the seasons are connected, green feed can be grown with green feed all the year round to meet the needs of fish. The grasses used for fish farming include ryegrass, sudan grass, alfalfa, bitter-selling vegetables, pennisetum, and red and white clover.
8. Integrated fish farming. That is to say, fish is mainly used for comprehensive management and comprehensive utilization of fishery, agriculture and animal husbandry. All localities can adopt the combination of fruit and grass carp and Sangji fish ponds in accordance with local conditions. They can also run the powder workshops and bean curd workshops near the fish ponds to solve the organic fertilizers and some feeds needed for fish farming to reduce the amount of concentrate feed and feeding. Quantity, reduce costs.
9. Insect breeding. All insects, cockroaches and cockroaches have a high protein content and are the best feed for fish. In the summer and autumn season, several insect traps were installed on the surface of fish ponds to induce various insects to directly feed fish. Artificially cultivated fly maggots, cockroaches, and mealworms are also feeds that feed on fish.
10. Fertilize and fertilize fish. (1) Green Fermentation Fermentation Method. The green fertilizer grass is piled up in shallow water at the leeward sunny side of the pool, and the livestock manure is pressed on the top. The livestock manure is pressed for 2 to 3 days to allow it to ferment and rot and decompose. After the stems and leaves are rotted, the stumps are removed. (2) Fertilizer Fermentation Method. Manure must be fully fermented before use, and human urine should be sterilized by adding 1% to 2% lime to kill pathogens and parasites. The decomposed human excrement is diluted with 2 times of fresh water, and then it is sprayed evenly. The livestock manure is decomposed and piled in the pond corner. The application rate is generally 250-400 kg per mu. (3) Mixed fertilizer fermentation method. After the green manure and manure were fermented and mixed, the 250 kg/mu acre was used to dilute with water to remove the sediment, and the fertilizer and water were evenly poured into the fish ponds.
