According to the current purchase price of catfish in the market, it is 3 ~ 5 yuan per catty, and the output value per mu can reach 30 ~ 50,000 yuan. The cost of catfish culture, including 0.28 yuan/tail seedling, feed, water, electricity and labor, is not less than 10000 yuan. Such an acre of catfish can bring farmers a profit of 20,000 to 40,000 yuan, and the breeding efficiency is very high. More importantly, the catfish breeding cycle is very short, and it can be released from the pool in 80 ~ 90 days. So you can breed two batches a year, and the annual net income exceeds 40 thousand yuan, which is much better than going out to work. In order to better cultivate catfish and achieve high yield, it is necessary to provide the best growth environment. The optimum growth temperature of catfish is 18℃ to 28℃, and the pH value is 7.5. The water quality should be changed regularly to maintain the water quality.
Water quality directly affects the growth of catfish. Therefore, in the process of catfish culture, we must observe the water quality and find that the water quality can be changed. It is recommended to change the water once every half month, and 30% of the water can be changed each time; Fill the tank with oxygen. Catfish has high density and high requirement for dissolved oxygen, so the dissolved oxygen in the water can't be less, so an oxygen generator can be set up. In addition, attention should also be paid to prevent catfish diseases, such as undifferentiated diseases, which are usually thrown out in less than one month, resulting in blisters on fry and swelling of fins.
If things are not finished in time, the fry will eventually rot and die. What fish in the fish pond make money now? In order to get high profits, it is very necessary to cultivate rare fish, because rare fish can get high returns. Raising fish, this kind of fish is a very expensive product now. It is said that the market price in some places is as high as 200 yuan/Jin. Why is it so expensive? Mainly because fish is a very picky culture environment, the first quality requires freshness, sufficient dissolved oxygen and no pollution. Mainly feed on small miscellaneous fish and shrimp in the pond. So reproduction is easy. At present, with the breakthrough of breeding technology, the yield per mu of some farmers can reach 120 ~ 150 kg, and with sporadic high prices, the profits are considerable.
