In recent years, the market price of conventional fish has fallen repeatedly, sometimes even close to the cost price, and fish farmers have lost money when they are careless. Can conventional fish be raised to make money? The author visited a number of large-scale breeding fish farmers, and summed up their successful experience based on the following 10 production recommendations.
First, pollution-free farming With the implementation of the pollution-free agricultural product access system, the production of pollution-free aquatic products will also be highly valued by people.
Second, a reasonable set of culture In general, adult fish in the fish pond more fish, they compete with the main fish for food, competition for oxygen. In this case, if the fertile fish with higher economic value are properly set in the intensive culture pool, the wild fish in the pond can be eliminated, and the economic benefits of the fish pond can be further improved. Taking black fish as an example, the black fish with 100 g per mu is used with 30 tails. The catch rate of black fish is calculated at 70%. The current year's merchandise size can be as long as 2 to 3 kg/tail, and black fish can be produced per mu. 40 to 50 kg of fish, calculated at 12 yuan/kg, can increase income by 500 yuan per mu.
Third, to strengthen daily management As the saying goes: "Three points of raising, seven points." From the fish ponds to the out of pond sales, every morning, the middle and evening to Xuntang, observe the fish activities and eating is normal. In high temperature seasons, rainy days, and low atmospheric pressure, it is necessary to turn on oxygen in time to prevent floating heads and pans from occurring. With the increase of temperature, the pond's food organisms are becoming more and more abundant, the water quality is prone to change, and water quality should be adjusted in a timely manner. Usually a small amount of fresh water is injected every 10 to 15 days, and the food field, tools, and water are regularly sterilized.
Fourth, a balanced listing starts every year from May to June, and the fishing market begins. In this way, adult fish not only sells for a good price, but also loosens the density of fish in ponds.
Fifth, fish farming does not follow the trend in the choice of aquaculture species, do not look at the wolfberry varieties to raise money to raise maggots, according to the entire market conditions and breeding structure to determine the cultured species.
6. Emphasis on new technologies. Priority should be given to those new aquaculture species with high market demand and high technological content. For example, the high-yielding aquaculture of ponds of stingrays, and the introduction of new technologies for breeding such as immunization of grass carp.
VII. Grass cultivation Fish In the present pond intensive culture mode, the feed cost accounts for about 80% of the total production cost. When we mainly raise some herbivorous fish, we can match some grass in the diet. Reducing the cost of breeding can also improve the feeding structure of fish and promote the growth.
VIII. Large-scale stocking For some cultured species (such as grass carp, head bream, squid, etc.), we can adopt large-scale fish species to increase the size of outlet ponds, thereby increasing the economic benefits of pond fish farming.
Nine, do a good job of fish disease prevention work, "fish farming is not awkward, rich and faint." According to the characteristics of fish diseases can not be found, we must do the usual fish disease prevention work, do not have any chance.
X. The more carefully selected feedstuffs, the more they should use high-quality feeds in the case of sluggish breeding conditions.
