Embodiment

[0024] 1) Pond conditions: select the pond with sufficient water source, fresh and pollution-free, easy to enter and drain, and the silt depth ≤10cm at the mouth of the pond; figure 1 As shown, the pond is divided into mandarin fish ponds 7×667m 2 , Large scale fish pond 30×667m 2 , The area ratio is 1:4.3, and the quantity ratio is 1:3.

[0025] 2) Qingtang disinfection: On April 10, dry ponds were exposed to the sun for 10 days. 15 days before the seedlings are placed, the pond mouth is soaked in 50cm of water, every 667m 2 Use 25kg tea seed cake to remove harmful organisms; 7 days before seedling, every 667m 2 Disinfect with 20kg of bleaching powder; 5 days before the seedlings are placed, water in to 2m, every 667m 2 Apply 150kg of decomposed organic fertilizer.

[0026] 3) Cultivation of Chiroptera: ① Seedling release time: May 8 and June 7 in the sunny afternoon, stocking the self-propagating Chiroptera water flower, soak the fry in 3% salt water for 25 minutes before releas...

Abstract

The invention discloses an anti-season cultivation method for siniperca chuatsi by taking a barbus capito as a forage fish. Fish fries are added according to different time and density to culture thebarbus capito so as to solve a problem of shortage in the forage fish at a low temperature and during an overwintering stage in siniperca chuatsi cultivation. The anti-season cultivation method for the siniperca chuatsi by taking the barbus capito as the forage fish enriches a forage fish category and avoids a risk that the forage fish carries viruses, the problems that cirrhinus molitorella can not survive in the later stage of siniperca chuatsi cultivation and the forage fishes are insufficient in winter in northern areas can be solved, anti-season cultivation can be realized, forage fish cost and a cultivation risk are lowered, and the economic benefit of siniperca chuatsi cultivation is obviously improved.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, and in particular to an off-season breeding method of Siniperca chuatsi using as bait fish. Background technique [0002] Siniperca chuatsi ( Siniperca chuatsi ), also known as mandarin fish, osmanthus fish, and seasonal flower fish, belong to the order Perciforme, Percichthyidae, and Siniperca. They are warm-water bottom carnivorous fish. The fish has excellent characteristics such as rich nutrition, delicious and tender meat, no intermuscularity, beautiful appearance, and fast growth. It is very popular among farmers and consumers. It is one of the important rare freshwater cultured species in my country. In 2018, the national output exceeded 335,000 tons, and the industry developed rapidly. In various farming modes of mandarin fish, the selection and matching of bait fish is the key. At present, the main bait fish at the opening and fry cultivation stage are grass carp, bream, silver carp, bi...
