What are the tricks for making money from conventional fish farming?

In recent years, the market price of conventional fish has kept falling, sometimes even approaching the cost price, and @#@233@#@ farmers lose money with the slightest carelessness. Can conventional fish farming still make money? The author visited some large fish farmers with relatively good farming profits and, based on a summary of their successful experience, offers the following 10 production suggestions.

1. Pollution-free farming. With the implementation of the pollution-free agricultural product access system, the production of pollution-free aquatic products will certainly receive great attention from people.

2. Reasonable polyculture. Generally, there are many wild and miscellaneous fish in adult fish ponds, and they compete with the main cultured fish for food and oxygen. In this case, if fierce fish with relatively high economic value are reasonably polycultured in intensive ponds, they can not only eliminate the wild and miscellaneous fish in the pond but also further improve the economic benefits of the fish pond. Take snakehead as an example: polyculture of 30 snakehead per mu at a size of 100 g each, with a capture rate of 70%, means the commercial fish that year can grow to 2-3 kg each, and each mu can produce 40-50 kg of adult snakehead. Calculated at 12 yuan/kg, each mu of pond can increase income by about 500 yuan.

3. Strengthen daily management. As the saying goes: "Three parts farming, seven parts management." From the time the fry are put into the pond until @#@136@#@ they are harvested, inspect the pond every morning, noon and evening to observe whether the fish are moving and feeding normally. In high-temperature seasons, on rainy days, and when air pressure is very low, turn on the aerator in time to strictly prevent floating-head and pond-wide fish kills. As the temperature rises, the pond's food organisms also become more abundant, and water quality is prone to change, so water quality should be adjusted in good time. Generally, inject a small amount of fresh water every 10-15 days, and regularly disinfect the feeding area, tools and pond water.

4. Balanced marketing. Start catching fish for market every year in May-June. In this way, the adult fish are sold at a good price, and the stock density of fish in the pond is also reduced.

5. Do not follow trends in fish farming. When choosing aquaculture varieties, do not farm whatever variety @#@3@#@; the farming varieties should be determined according to the overall market situation and farming structure.

6. Value new technologies. Priority should be given to new aquaculture varieties with large market demand and high technological content. For example, new farming technologies such as high-yield pond farming of yellow catfish and immune injection farming of grass carp.

7. Grow grass to feed fish. In the current intensive pond farming model, feed cost accounts for about 80% of the entire production cost. When mainly farming some herbivorous fish, we can mix some green grass into the daily ration; this can both reduce farming costs and improve the fish's feeding structure, thereby promoting growth.

8. Stock large-sized fingerlings. For some farmed varieties (such as grass carp, blunt snout bream, crucian carp, etc.), we can adopt the method of stocking large-sized fingerlings to increase the harvest size, thereby improving the economic benefits of pond fish farming.

9. Do a good job of fish disease prevention. "If fish farming avoids disease, you will be dizzy with wealth." According to the characteristic that fish diseases are not easily discovered, do a good job of routine fish disease prevention and do not have any false hopes.

10. Choose feed carefully. The worse the farming market situation, the more important it is to choose high-quality feed, as fish constitution declines and diseases occur frequently.
