Embodiment Construction

[0012] A method for imitating ecological cultivation of Chinese mitten crabs and breeding whole male yellow catfish, the method comprises the following steps:

[0013] 1) Selection and disinfection of fish ponds: the area of ​​fish ponds is 3350-6700 square meters, the water depth is 1-1.5 meters or more, the thickness of silt is 13-17cm, the dissolved oxygen in water quality reaches 5 mg / L, the transparency is more than 25 cm, and an aerator is equipped. Use 150-200 kg of quicklime or 6 kg-8 kg of bleaching powder per mu to make slurry and sprinkle evenly in the whole pool, inject 30-50 cm of water after the toxicity disappears, wrap the water inlet with double-layer dense mesh, plant submerged plants in the pool, and plant The area is 60% of the water surface, and the pond should be disinfected with water 10 days before stocking, and the water depth should be controlled between 1-1.2m;

[0014] 2) Putting fish fingerlings and crab seedlings: choose Chinese mitten crab seedli...

Abstract

The invention relates to an imitation ecological cultivating method for intercropping the Chinese mitten crab with the all-male yellow catfish, which includes the steps: selecting and sterilizing a fishpond, throwing in catfish fry and crab seeds, feeding the fish fry and the crab seeds, and regulating water quality. The imitation ecological cultivating method has the advantages that water productivity is expanded, growth advantage of the all-male yellow catfish is given to full play in the method, water spatial ecological advantages are fully utilized, productive potential of the fishpond is tapped further, utilization coefficient of pond water is improved, economic benefit is improved, yield and production value of the all-male yellow catfish in intercropping are improved, and comparative benefit of the Chinese mitten crab in pond culture is improved.

Description

technical field [0001] The invention relates to a pond culture method for fishery production of Chinese mitten crabs, in particular to a method for imitating ecological culture of Chinese mitten crabs for breeding whole male yellow catfish. Background technique [0002] It is common to breed Chinese mitten crabs and mandarin fish in ponds, but mandarin fishes use live fish as bait, so it is impossible for mandarin fish to eat up all the live fish that are often fed. One of the escaped wild fish competes with the Chinese mitten crab to affect the output of the main fish, and the two cause certain dangers to the molting of the Chinese mitten crab and affect its survival rate. In aquaculture production, rats are often thrown into the trap and seriously affect the production of mandarin fish in nesting. [0003] Yellow catfish ( Pelteobagrus fulvidraco ) is an important economic edible fish in my country. The market demand is constantly increasing, and the market price is risi...
