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

[0032] The breeding method of red-eyed trout as mandarin fish off-season breeding bait fish comprises the following steps:

[0033] (1) Clear pond disinfection

[0034] 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 cultivation water quality; (2) Cultivation conditions

[0035] 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;

[0036] (3) Summer flower cultivation

[0037] 72 hours after the fertilized eggs hatched, the fish fry had good swimming ability, and the intestinal tube was completely formed. The seedli...

Abstract

The invention discloses a culturing method of squaliobarbus curriculus regarded as forage fish for out-of-season culturing of mandarin fish. The culturing method belongs to the technical field of aquaculture, and comprises the following steps of (1) pond cleaning and disinfecting; (2) culturing conditions; (3) summer flower culturing; (4) fingerling rearing. The method provided by the invention takes the lead in breaking through the key technology that live forage fish i.e. dace suitable for the later period of culturing of the mandarin fish cannot survive through the winter in Northern China, creatively provides the idea of regarding the high-yield cultured fishes i.e. squaliobarbus curriculus with high low-temperature resistant capacity as the forage fish for the later period of culturing of the mandarin fish, effectively ensures the supply of the forage fish for the mandarin fish to live through the winter and in later period of culturing from the following spring to August by an efficient culturing mode of putting fries in different months, thoroughly solves the problem of the restriction of insufficient and unwell supply of the forage fish suitable for the later period of culturing of the mandarin fish in winter in Northern China, and provides important forage fish guarantee for the out-of-season culturing of the mandarin fish.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating red-eyed trout as a bait fish for off-season culture 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 th...
