Problems solved by technology

In the existing artificial breeding, farmers generally adopt the method of breeding other adult fish (such as grass carp) to breed adult red-eyed trout, but the effect is not ideal. The adult fish obtained from farming are small in size, with low survival rate and yield per mu

Embodiment 1

[0019] Breeding method of adult red-eyed trout: choose a medium-sized pond with a water surface of 10 mu and a water depth of 1.8m. Fifteen days before the species of red-eyed trout are put in, 150kg of quicklime per mu is used to evenly spray and disinfect the bottom of the whole pond. After disinfection, the mud at the bottom of the pond ( The thickness of the mud is 15cm) to freeze and dry for 10 days, inject 120cm of clear water, and apply 250kg of fermented chicken manure per mu to cultivate water quality to ensure that the water body transparency is 30cm when fish species enter the pond. For fish species, when the water temperature is 12-19°C, feed once a day, and once at around 13:00, the feeding amount is 0.5% of the total weight of the surviving fish species in the pool. When the water temperature is 19°C-25°C 2 times a day, once at 10:00 and 16:00, the amount of feeding is 2% of the total weight of surviving fish species in the pond, when the water temperature is abov...

Embodiment 2

[0022] Breeding method for adult red-eyed trout: choose a medium-sized pond with a water surface of 20 mu and a water depth of 1.8m. Fifteen days before the species of red-eyed trout are put in, 200kg of quicklime per mu is used to evenly spray and disinfect the bottom of the whole pond. After disinfection, the mud at the bottom of the pond ( The thickness of the sludge is 20cm) to freeze and dry for 10 days, inject 140cm of clear water, and apply 250kg of fermented chicken manure per mu to cultivate water quality. When the fish species enter the pond, the water body transparency is 40cm, put red-eyed trout species, and raise red-eyed trout with artificial feed species, when the water temperature is 12-19°C, feed once a day, and feed once at around 13:00, and the feeding amount is 0.5% of the total weight of the surviving fish species in the pond; when the water temperature is 19°C-25°C , twice a day, once at 10:00 and 16:00, the amount of feeding is 1% of the total weight of t...

Abstract

The invention discloses a farming method for a squaliobarbus curriculus adult fish, which comprises the following steps: 1, performing manual disinfecting for a farming pool by quicklime before the squaliobarbus curriculus fingerlings are put into the pool, freezing and drying the farming pool, pouring water into the farming pool, and applying fermentation organic fertilizer to cultivate water quality; and 2, putting the squaliobarbus curriculus fingerlings into the farming pool, feeding artificial diet, and then putting freshwater shrimps and plagiognathops microlepis fingerlings into the farming pool to be mixed with the squaliobarbus curriculus fingerlings. According to the method, due to the adoption of the method, not only is the cultured adult fish large in size and high in standard, but also the adult fish survival rate is high and the acre yield is high; with suitable breeds for mixing with the squaliobarbus curriculus fingerlings and the reasonable artificial diet, the disease-resistant rate and survival rate of the squaliobarbus curriculus adult fish are improved, and accordingly, the standard and weight of the adult fish are effectively improved, and the acre yield is also improved.

Description

technical field [0001] The invention relates to a method for cultivating adult red-eyed trout, which belongs to the field of aquaculture. Background technique [0002] Red-eyed trout belongs to Cyprinidae, Cyprinidae, Yaluo subfamily, and red-eyed trout. It is commonly known as red-eyed fish and wild grass carp in Zhenjiang, Jiangsu. It is distributed in various water systems across the country. It is a fast-growing, adaptable, miscellaneous food, and commercial value High economic fish. [0003] The red-eyed trout inhabits the middle layer of the water body, and can feed on aquatic plants such as bitter grass, Elodea, duckweed, and Hydrilla verticillium in the water body after reaching a body length of 5 cm in the natural water body. In the existing artificial breeding, farmers generally adopt the method of culturing other adult fish (such as grass carp) to breed adult red-eyed trout, but the effect is not satisfactory. The adult fish obtained by farming are small in size,...
