Tips for making money by raising conventional fish

In recent years, the market price of conventional fish has fallen again and again, sometimes even close to the cost price. @ # @ 233 fish households lose money if they are not careful. Can you still make money from conventional fish farming? The author visited some large fish farmers with better culture benefits, and put forward the following 10 productive suggestions on the basis of their successful experience.

With the implementation of the access system of pollution-free agricultural products, people will attach great importance to the production of pollution-free aquatic products.

2. Under normal circumstances, there are more wild miscellaneous fish in the adult fish pond, and they compete for food and oxygen with the main fish. In this case, if the ferocious fish with high economic value are cultivated reasonably in the intensive culture pond, it can not only eliminate the wild miscellaneous fish in the pond, but also further improve the economic benefit of the fish pond. Take black fish as an example, 30 black fish with a specification of 100 grams per mu are raised, and the initial catch rate of black fish is calculated at 70%. In that year, the standard of commercial fish can grow to 3 kilograms per mu, and adult black fish can produce 40 kilograms per mu. Calculated at 12 yuan per kilogram, the income per mu of pond can be increased by about 500 yuan.

Third, strengthen daily management, as the saying goes, "three-part cultivation, seven-part management." From the time the fish species go into the pond to the time they come out of the pond, they have to patrol the pond every morning, middle and evening to observe whether the fish's activities and eating are normal. In the high temperature season, cloudy and rainy days, when the air pressure is very low, it is necessary to turn on the machine in time to increase oxygen and strictly prevent the phenomenon of floating head and flooding pool. With the increase of air temperature, the bait organisms in the pond become more and more abundant, and the water quality is easy to change, so it is necessary to adjust the water quality in time. Generally, a small amount of new water is injected into the food farm, tools and pool water regularly every 10 minutes and 15 days.

Fourth, balanced listing starts fishing and listing from May to June every year. In this way, adult fish not only get a good price, but also loosen the density of fish in the pond.

5. Fish farming does not follow the trend when choosing aquaculture varieties, do not look at what species are raised, but should determine the aquaculture species according to the entire market situation and culture structure.

Pay attention to new technology. Priority should be given to those new aquaculture varieties with high market demand and high scientific and technological content. For example, new culture techniques such as high-yield culture of Pelteobagrus fulvidraco in ponds and immune injection culture of grass carp.

7. Recommended fish culture in the current pond intensive culture model, the feed cost accounts for about 80% of the total production cost. when mainly raising some herbivorous fish, we can match some grass in the diet, which can reduce the culture cost. it can also improve the feeding structure of fish to achieve the purpose of promoting growth.

For some farmed species (such as grass carp, blunt snout bream, crucian carp, etc.), we can put in large-scale fish species to improve the size of the pond, so as to improve the economic benefits of fish culture in the pond.

9. Do a good job in the prevention of fish diseases. "Fish farming is not plague, and you are so rich that you get dizzy." According to the characteristics that fish disease is not easy to be found, it is necessary to do a good job in fish disease prevention and do not have any fluke mentality.

Ten, careful selection of feed the more depressed the breeding market, the more we should choose high-quality feed, the decline of fish physique, frequent disease.
