Problems solved by technology

At present, in the large-scale culture of mandarin fish in the area north of the Yangtze River, due to the limitation of natural conditions and the influence of factors such as the breeding season of bait fish, the culture of mandarin fish once a year mainly relies on dace which belongs to warm water as bait fish. Mode, which restricts the improvement of the economic benefits of the mandarin fish farming industry

Embodiment 1

[0024] The method for off-season cultivation of mandarin fish comprises the steps:

[0025] (1) Clear pond disinfection

[0026] 7 days before the release of seedlings, disinfect the clear pond with quicklime to control the water quality of the water source, and filter the incoming water with a dense mesh to obtain the water quality for cultivation; (2) Cultivation of bait fish

[0027] In order to ensure the supply of bait fish in the middle and later stages of off-season culture of mandarin fish, solve key problems such as the inability of overwintering bait fish, insufficient supply and unpalatable bait fish in the late stage of mandarin fish culture, and choose to breed the high-yielding aquaculture fish Trichogramma trout that can survive the winter. For the species of red-eyed trout, summer flowers of red-eyed trout were stocked in ponds in May, June, July and August respectively in the second half of the year. The stocking size was 5,000-12,000 / kg. In July, November an...

Embodiment 2

[0042]A method for cultivating bait fish red-eyed trout, comprising the steps of:

[0043] (1) Clear pond disinfection

[0044] 7 days before the seedlings are released, disinfect the clear pond with quicklime to control the water quality of the water source, and filter the incoming water with a dense mesh to obtain the water quality for cultivation; (2) Cultivation conditions

[0045] The suitable water temperature for seed cultivation is 20-30°C, the water depth of the fry pond is 1.2-1.5m, and the water depth of the fingerling pond is 1.5-2.0m; the water supply and drainage systems of the fry pond and the fingerling pond are independent, and both are equipped with anti-escape and anti-enemy Hazardous filtration facilities are equipped with aerators;

[0046] (3) Summer flower cultivation

[0047] 72 hours after the fertilized eggs hatched, the fish fry had good swimming ability, and the intestinal tube was completely formed. The seedlings were put into the pond to grow in...

Abstract

The invention discloses a mandarin fish out-of-season culture method, and belongs to the technical field of aquaculture. The method includes the steps: (1) cleaning a pond to realize disinfection; (2) culturing forage fish; (3) culturing mandarin fish. According to the mandarin fish out-of-season culture method, by changing a traditional mandarin fish culture method and culture baits, curriculus is used as a bait, the mandarin fish out-of-season culture method adapting to curriculus bait feeding is developed, the problem that forage dace cannot live through winter in a later period of traditional mandarin fish culture in a northern area can be solved, a mandarin fish out-of-season culture mode of culturing the fish for multiple times in a year is creatively researched and developed, adult mandarin fish can selectively appear on the market in any time periods all year round including the following spring, any specifications of mandarin fish appearing on the market can be provided in different seasons, the requirements of different domestic markets are met, and economic benefits and market values of mandarin fish culture industry are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for out-of-season cultivation of mandarin fish. Background technique [0002] Mandarin fish, also known as sweet-scented osmanthus fish and seasonal flower fish, belongs to the order Perciformes; mandarin fish is delicious and nutritious, rich in protein and amino acids, has few spines and more meat, and is deeply loved by consumers. In recent years, the culture of mandarin fish has developed rapidly, and the breeding area has been increasing. In mandarin fish culture, the supporting technology of bait fish is one of the key issues that must be solved. Grass carp and group head bream are mainly used for mandarin fish feeding and seedling breeding, crucian carp and silver carp are mainly used for fingerling breeding, and dace are mainly used for the middle and late stages of mandarin fish breeding. Dace, which is the main bait fish for adult mandarin fis...
