Carp is one of China's freshwater valuable fish, it has a high economic value, known as "freshwater grouper." Since the carp needs to feed live fish, it is difficult to popularize the mode of carp-based fish farming in large scale. Last year, we chose to put together a 150-acre pond to raise squid summer flowers. After 6 months of cultivation, we achieved good results.
First, materials and methods
1. Pond conditions The pond is sandy loam, with a depth of 15-20 centimeters, an area of ​​5-10 acres and an average water depth of 1.5-2.0 meters. The water source is abundant, the water quality is fresh, the drainage is convenient, and the wild fish are abundant.
2. Fish species will be released before the Spring Festival. The mu will be put into specifications of 0.3-0.75 kg of 200 pond grass fishes, 0.15-0.4 kg of white catfish of 20 fishes, 0.3 kg of white catfish of 120 fishponds, and 40 cauliflowers of flowers; June 10 acres. Five to six centimeters of carp summer flowers are nestled; on July 10, 1,000 acres of summer flowers are planted in acres.
3. The feed is fed with grass carp to feed fodder. According to the supply of green fodder, a certain amount of pelleted compound feed is appropriate, and after July 10th, after the shrubs are used, some cakes and rice bran are regularly fed. Such mixed powders are used for feeding the flower buds summer flowers and the self-incubated white waxy seedlings in the pond, so that the bait fish and the squid grow synchronously, so that the squid can ingest suitable fish baits of appropriate specifications.
4. Water quality regulation Before the catfish summer flower is not under the pond, the amount of water exchanged should be properly controlled to maintain a suitable fertilizer for the pond water in order to cultivate more plankton and accelerate the growth of the whitefish in the pool. In front of the flower pond, the white peony and grass carp, which meet the specifications, are harvested and marketed. After the squid has spent its summer in the pond, it gradually increases the amount of pool water exchanged. After July, micro-fluid fish farming, that is, exchange of pool water for about 7 days, keeping the water fresh and controlling the transparency at 40 centimeters ensures the high dissolved oxygen in the pool water.
5. Disease Prevention and Control Ponds Before the release of fish, 150 kg of lime should be used to thoroughly clear the pond. After the fish is stocked, they should be soaked with 5 mg/L copper sulfate to prevent parasites. Before the catfish summer flower is put into the pond, it is soaked with 2% salt water for 10-15 minutes. After that, the water quality is adjusted once every half month with 20g/m3 quicklime, and micro-flowing water is maintained during the high temperature season.
6, daily management adhere to the early, middle and late 3 times to inspect the pond, grasp the fish feeding situation, floating head condition, water quality changes, fish movements and the occurrence of disease, etc., in order to take appropriate measures in a timely manner.
Second, the test results
After 180 days of cultivation, they were arrested from December 12 to December 20, with an average yield of 450.4 kg per mu, and a net production of 332.4 kg per mu. Among them, perch yield was 17.3 kg per mu, which increased the economic benefits by more than 600 yuan and achieved good results. Economic and ecological benefits.
Third, summary and discussion
1, in the management of convenient and feasible management does not require special requirements, just spend a little seed costs, low cost, and aquaculture efficiency than before the uncultivated increase of 600 yuan per acre, raising the economic benefits of pond culture.
2, the main, set of fish species specifications to be suitable for carp is best to be 5-6 cm above, the other fish stocks are first to consider whether it poses a direct or potential threat to the carp. Squid can prey on any fish whose body length is 60% to 70% and whose body height is smaller than its mouth crack. Moreover, carp grows fast. With the growth of individual carp, the potential harm to other fishes also increases. Therefore, adult fish ponds are reared in stocking ponds, and the size of other fish stocks for stocking should be large. Generally, they are suitable for more than 2 years of age, and the body length is more than 1 times larger than that of carp.
3. Sufficient bait fish is the key to raising the yield of catfish. Although there are more wild fish and shrimp in the pond, it still cannot meet the needs of catfish in the later period. Therefore, in addition to nesting large-scale whitefish in ponds, we also cultivated summer flowers after July to supplement the shortage of bait fish and to accelerate the growth of carp.
4, to always control the density and structure of the fish to adopt large-scale species of fish stocking, early through strong feeding, appropriate fertilization and control of water flow and other measures to accelerate the growth of pond fish, fish before the summer flower pond, namely At the beginning of May and the beginning of June, each round will be caught, and all the flowers, white locusts and some grass carp of more than 1 kg will be caught and listed on the market, which will be beneficial to the growth of the pond and give full play to the potential of the pond. At the same time, the squid will be solved. The contradiction between the fertilized water and the white peony is beneficial to the growth of the bonito and ensures that the conventional fish production is not affected while the mullet is raised.
5, to prevent and treat fish diseases in a timely manner 20 grams / m3 of lime every 10 days can better adjust the pH, but also prevent disease. If salmon parasites are found, they should be promptly treated. A 0.7 g/m3 copper sulphate and ferrous sulfate mixture can be used to splash the whole cell.
