Problems solved by technology

There are three main problems in the commercial culture of mandarin fish with live bait: 1. The cost of culture is high, and the live bait needs to be cultured in matching ponds and personnel, and the requirement for the supply of live bait to maintain the commercial culture of mandarin fish is high; 2. The survival rate of fish fry is low, and mandarin fish fry feed on other fry when they emerge from the film. Therefore, the survival rate of fry under natural conditions is low; 3. Live bait breeding is also one of the important reasons for the occurrence of mandarin fish epidemics, especially leading to outbreaks Important Factors in Sexual Prevalence
[0004] Due to the above problems, although mandarin fish has become a breeding hotspot due to its high economic value and preciousness, its rare living characteristics have brought great difficulties to its breeding, especially large-scale farming.
[0005] At present, there is no specific breeding method for domesticating mandarin fish to feed on compound feed

Embodiment 1

[0061] In the seedling field of Datang Town, Sanshui District, Foshan City, choose a standard thick pond for mandarin fish seedlings. The standard thick pond is a cement pond with an area of ​​100m 2 , the water depth is 0.6m, and the aeration facilities are arranged. The mesh is 1.5cm without knotting, enclosing 1 / 4 of the area of ​​the cement pool, setting the feeding point, and placing 3 bottom aeration discs at the feeding point, which are triangular in shape and controlled The sunlight intensity is 5000-15000lux, 24 hours running water, the water change is 3-6 times, and the seine is removed after 3-4 days of feeding. 20,000 mandarin fish seedlings with the same size and an average weight of 4.5 g were stocked.

[0062] At the beginning, starve the mandarin fish seedlings first, and after checking that there is no food in the stomach of the mandarin fish seedlings, only the oxygenation facilities at the feeding point are left, and the nearby oxygenation facilities are clo...

Embodiment 2

[0064] In the seedling field of Datang Town, Sanshui District, Foshan City, a standard thick pond for mandarin fish seedlings was selected. The standard thick pond is a pond with an area of ​​6 acres and a water depth of 1.2-1.5m. The aeration facilities are arranged and the mesh is 1.8cm without knots. Net, Enclosing Pond 260m 2 , build a feed table, set up feeding points, place 8 bottom aeration plates at the feeding points, 6 in a circular layout, place 2 aeration plates in the middle, and use shade nets or other materials with a shading rate of 90%. Control the sunlight intensity to 10000-15000lux, and the shading area is 60m 2. Use photosynthetic bacteria, EM bacteria, etc. to manage water quality regularly, and pay attention to detecting changes in ammonia nitrogen and nitrite nitrogen in pond water. 20,000 mandarin fish seedlings with the same size and an average weight of 5.6 g were stocked. At the beginning, starve the mandarin fish seedlings first, and after check...

Abstract

The invention relates to a Siniperca chuatsi aquaculture method, and particularly relates to Siniperca chuatsi domestication aquaculture method for allowing Siniperca chuatsi to eat compound feed, which can effectively domesticate the Siniperca chuatsi so as to allow the Siniperca chuatsi to eat the 100% compound feed; and the success rate of domestication can reach more than 93%, even more than 96%. The method can domesticate the Siniperca chuatsi in a cement aquaculture pool and can successful domesticate the Siniperca chuatsi in a pool, and in this way, the technical difficulties in intensive feeding the Siniperca chuatsi can be broken through, the problem that live bait is used in Siniperca chuatsi aquaculture can be solved, the Siniperca chuatsi can be domesticated and eat the artificial compound feed in the pool or the cement aquaculture pool, and a solid foundation is lied for high-efficiency and low-cost promotion of Siniperca chuatsi large-scale artificial aquaculture.

Description

technical field [0001] The invention relates to a method for cultivating mandarin fish, in particular to a method for cultivating mandarin fish to domesticate and ingest compound feed. Background technique [0002] Mandarin fish, also known as mandarin fish, is a rare freshwater fish belonging to the suborder Perciformes. The fast-growing, large-bodied mandarin fish, which is suitable for breeding, is more and more favored by consumers. It is called the main species in China's famous and high-quality aquaculture. The market demand is in short supply, and the market price continues to rise. However, the life characteristics of this kind of fish are quite peculiar. They feed on live fish and shrimps for the rest of their lives since they start eating, and refuse to eat dead bait or compound feed. This phenomenon is very rare in fish. [0003] Since the commercial farming of mandarin fish, they have been fed with live bait, and mandarin fish fry have been fed on other species ...
