specific Embodiment

[0025] A kind of breeding method of pollution-free California perch, comprises the following steps:

[0026] 1) The construction of rearing pond: rearing pond is made of two fish ponds and the filter pond between two described fish ponds, the long 10m of described fish pond, wide 5m, deep 2m, the filter pond of described filter pond 10m long, 1m wide, and 3m deep, the walls of the two fish ponds are made of cement, and the bottom of the pond is muddy. The walls of the filter ponds are provided with inlet and outlet ports. The transparency of the pool water is 30-35cm, the pH value of the pool water is 6-8.5, the water temperature is 15-30°C, and the water depth is 1m-1.5m. Before putting in the fry, the fish pond is disinfected with quicklime or potassium permanganate;

[0027] 2) Stocking of fish fry: select 0.5-2kg fish fingerlings, which are neat, uniform, and disease-free fry, and start stocking in late May. Put the palatable feed fish in the fish pond within 5 days, choo...

Abstract

The invention provides a pollution-free microptenus salmoides cultivation method which is capable of solving the problems of low survival rate and slow growth speed in the prior art. The pollution-free microptenus salmoides cultivation method comprises the following steps: 1), rearing pond construction; 2) fish fry stocking; 3) feeding management; 4) prevention and treatment of diseases; and 5) daily management. The microptenus salmoides are cultivated according to specifications and body length, so that occurrence of a phenomenon that the microptenus salmoides kill one another is completely eradicated to a certain degree; fresh and palatable baits are adopted, so that the growth speed of the microptenus salmoides is relatively rapid, meanwhile freshness and rich dissolved oxygen of water in a pond are ensured, and a comfortable growth space is provided for growth of the microptenus salmoides.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating pollution-free California perch. Background technique [0002] California perch is a wide-temperature carnivorous freshwater rare fish. It has the advantages of large body, fast growth, strong adaptability, less disease, easy to catch, and delicious meat. It can be raised alone or mixed with other domestic fish. California Bass likes to live in sandy or sandy muddy and slow-flowing water with low turbidity. It is one of the important economic fish for the development of pond culture. At present, the cultivation of California seabass mostly adopts a flat culture mode, that is, in cement ponds or sandy ponds. Tiles, shells, etc. are laid on the bottom of the stone pond as the habitat for perch. This farming model is simple to operate and low in cost, but has low survival rate, low density, and slow growth. [0003] During the long-term culture of perch...
