The squid, commonly known as Sanli fish and Sanlai fish, belongs to the genus Euphorbiae, Acipenseridae and Euphorbia and is a rare and precious economic fish of our country. It has a longer body, flat and high side, medium to large head, large mouth, large and thin scales, and ribbed scales on the abdomen. The head and back are gray, with a bluish-green luster on the side of the body, and white and silver on both sides of the body and belly. General body length 25 cm to 40 cm, a body weight of 1 kg to 1.5 kg, the largest individual up to 3.5 kg to 4 kg. Carp is a migratory salty and freshwater amphibious fish that is distributed in the Yellow Sea, East China Sea and South China Sea. It is distributed in the Yangtze River, Xiangjiang River, Minjiang River and Pearl River in freshwater. Every spring and summer season, the sea enters rivers, spawns and breeds. It takes time, and the season is very accurate.
The squid is a warm water pelagic fish, and has a wide range of temperature adaptation. The suitable temperature is 2°C to 38°C, and the optimum water temperature is 22°C to 30°C. It is an anadromous species that has in-depth riverside feeding and colony spawning habits. Most foods are mainly plankton-infested, such as rotifers, copepods, sword water crickets, basal glycosides, etc. They also eat diatoms and other organic detritus and eat young fish and shrimp. However, under conditions of artificial breeding, large amounts of protein-rich pellets are also eaten, even at night.
Salmon is delicate, delicious, nutritious, and economically valuable. According to analysis, each one hundred grams of fish contains 16.9 grams of protein, 17 grams of fat, also contains sugar, ash, calcium, phosphorus, iron, riboflavin, niacin and other nutrients, the "king of fish" in the world. As the squid feeds on zooplankton, the meat is tender, smooth, and has a unique fish flavor. Squid also has medicinal therapeutic value. According to medicine books and other records, squid meat is sweet and warm, has nourishing and strengthening functions, and also has anti-inflammatory and detoxifying effects. Therefore, in ancient times, the squid was a supplement to the local tribute to the imperial court and was included in the Imperial cuisine. However, in recent years, due to various reasons, such as overfishing and breeding of broodstock, feeding of fish, and pollution of rivers and waters, the natural resources of squid have dropped drastically. According to reports, the production of catfish has been no more than 10 tons in recent years. Since the 1980s, the population of carp has gradually been in a state of endangerment. The market is very expensive. In 2000, there were seafood in Shunde District, Foshan City, Guangdong Province. The purchase price of squid and adult squid is 400 to 440 yuan per kilogram, and the price of sashimi sold to diners is 520 to 560 yuan per kilogram, but it is still popular.
At present, there is no supply of carp in local markets and restaurants, so the development of artificial breeding is imperative and the breeding prospects are quite promising.
Mackerel was originally a salty, freshwater amphibious fish that can be farmed. According to the introduction of the trial and training experience, the breeding methods are: 1. The pond can be purely bred (ie, monocultured, but a small amount of squid and whitefish can be bred to control the water quality). Pond area of ​​3 acres ~ 5 acres, water depth of 1.5 meters is appropriate. 2. Fish pond polyculture. The stocking of common carp in catfish ponds, home fish ponds or other high-quality fish ponds can not only effectively control the over-breeding of zooplankton, but also help regulate water quality, increase fish production, and increase economic efficiency. In addition, reservoirs, lakes, and large-area ponds can be used for breeding, but stocking specifications should be slightly larger. By using various methods of breeding and strengthening management, better results can be obtained. Such as pure ponds, stocking 3 cm to 4 cm per acre of 1300 to 1500 fry, its survival of more than 90%, per mu up to more than a thousand of.
