Umbrella efficient breeding technique
The squid is a species of oystercatcher, a family of breams, and is a large-scale, freshwater fish economical fish with high economic value. The squid has less bone spurs, high meat content, rich nutrients, new detoxification, nourishing and nourishing, nourishing blood and promoting wound healing. Therefore, the mullet is welcomed by Southeast Asian countries and the Hong Kong and Macao markets.

I (Note: Jiangsu Yixing) mainly uses small water intensive intensive cultivation, rapid growth, high return rate, per mu over 2000kg per mu, can achieve more than 20,000 yuan per mu output value, mu gain more than 5,000 yuan.
1 Ponds require mullet intensive ponds to be well earthed ponds, not only cost low, but also suitable for their habits, to facilitate water quality regulation. The water surface can be more than 300 square meters, the water depth is more than 150cm, the bottom of the pool is 10~15cm mud, the surrounding environment of the fish pond is quiet, drainage and irrigation are convenient. Prior to the release of fish species, the fish should be completely drained and sterilized with fresh lime ponds. After 15 days, the fish should be irrigated. Around the fish pond, there is a block of 100 cm or more, and the center or the corner of the pond is transplanted with aquatic plants, accounting for about 1/5 to 1/6 of the aquaculture water surface, so as to regulate water quality and provide shelter and shelter for fish.
2 Fish Feeding
The fish species will be released from February to March, with specifications of 50-80g/tail, requiring a healthy, disease-free, non-injury body, with 5 to 6 tails per square meter. The same species of pond fish should be large and small. When the fishes are pooled, they are disinfected with 0.2-0.5 g/m3 malachite green or 2%-3% saline.
3 Feeding mullet to carnivorous fish. At present, most of the artificially cultivated blackbirds are fed fresh live fish such as small fish, shrimp, snails, and oysters. When feeding fresh live bait artificially, pay attention to freshness, cleanliness, and soaking with 6% to 8% of salt solution for 10 to 15 minutes before feeding. The feeding amount is 6% to 8% of the fish's body weight. Daily, quantitative feeding 2 to 3 times. Such as fish and shrimp, can also be fed to other animal waste, such as livestock, poultry viscera, but also pay attention to fresh, clean, chopped and disinfected when feeding. Can also be based on the nutritional needs of mullet prepared artificial diet to supplement the lack of fresh live bait.
4 Feeding management
4.1 Water Management Pond intensive culture mullet fishes have large stocks and feeds; therefore, attention should be paid to water quality management. Change the water every 10 to 15 days 1 time, each time changing the water 10 ~ 15cm, every 20 days with lime water Quanchiposa 1, each with lime 10kg per acre to keep the pool water fresh.
4.2 Prevention of Fish Diseases Due to the small size and high density of aquaculture water, the disease of mullet fish farming has been increasing year by year. The prevention and control of squid disease is an indispensable and important link in the development of high-efficient culture. In addition to strengthening aquaculture management, attention must be paid to the prevention and control of saprophytic disease, putrefaction disease, ascites disease, and gill disease. Aquatic mildew must be disinfected with malachite green or salt water after injury to fish. Toxicosis, regular use of bleach or strong chlorine fine Quanchiposa prevention; early onset of furazolidone mixed baits, each course of 3 to 5 days, 2 courses per month. Ascites disease should be promptly given to the bait after discovery. 100kg of fish should be fed with sulfamethoxazole or kanamycin 6g mixed bait. Within 3 days and 1 course of treatment, 2 to 3 courses of treatment can be cured. Parasitic gill disease, 0.3 g/m3 of trichlorfon crystals can be sprayed once a month; bacterial gill disease, with 1 g/m3 of bleach or 0.3 g/m3 of strong chlorine. Disinfection and sterilization, while feeding baits, every 100kg of fish fed with furazolidone 4g bait, a course of 3 to 5 days.
4.3 To prevent escaping from sticking to the patrol pond, special attention should be paid to thunderstorm days to prevent the mullet from jumping off the shore or "aisle" to escape.
5 The fishing market has become serious due to greediness, fast growth, competition for food, and bullying. Therefore, we must insist on catching large and small, grading rearing. Since June, nets have been pulled once a month, and large-scale squid will be listed on the market or pooled in order to ensure that the size of the squid in the pool is the same. In late December, when the fish caught in dry ponds was caught and the commodity fish caught could not be sold for a while, they could be raised temporarily to be raised for sale on or after the Spring Festival.
