Tips for raising conventional fish to make money

In recent years, the market price of conventional fish has fallen again and again, sometimes even close to the cost price. @ # @ 233 fish households will lose money at the slightest inadvertent. Can you still make money from conventional fish farming? With this problem, our reporter visited some large fish farmers with good benefits in the province and put forward the following 10 productive suggestions on the basis of their successful experience.

1. Advocate pollution-free breeding. 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. Anyone who wants to be in an invincible position in the future market economy must be well prepared in this regard.

2. Reasonable cultivation of famous and special fish with the function of "removing wild". In general, there are more wild miscellaneous fish in the adult fish pond. they compete for food and oxygen with the main fish, which not only affect the growth of the main fish, but also the price is on the low side. In this case, if the ferocious fish with high economic value can be 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%. The commodity specification of that year can grow to 2 kilograms per mu, and the adult black fish can produce 40 kilograms per mu. Calculated at 12 yuan per kilogram, the pond can increase income by about 500 yuan per mu.

3. Strengthen daily management. As the saying goes, "three points of cultivation, seven points of control." 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 every 10 to 15 days, and the food farms, tools and pool water are disinfected regularly.

4. Balanced listing. Fishing begins to appear on the market 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 species, don't look at what species are raised, but what most mariculturists have lost money or raised less. The breeding species should be determined according to the whole market situation and culture structure.

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

7. Fish farming is recommended to reduce costs. 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 (such as grass carp, blunt snout bream, etc.), we can match some grass in the diet, which can not only reduce the culture cost, but also improve the feeding structure of fish to achieve the purpose of promoting growth.

8. Large size stocking. For some farmed species (such as grass carp, blunt snout bream, crucian carp, etc.), we can put in large 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 fish disease prevention. "there is no plague in fish farming, 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.

10. Choose the feed carefully. The more depressed the breeding market, the more necessary to choose high-quality feed, low-quality feed can not only cause the decline of fish physique, frequent disease, but also lead to the increase of waste excreted by fish, increasing the pressure of pond water quality management.
