Problems solved by technology

[0002] Perch, also known as flower perch, Zhaihua, perch board, four-rib carp, is mainly distributed in the western Pacific Ocean and the coast of China, among which there are many in the Yellow Sea and Bohai Sea. Nutrients such as protein, fat, carbohydrates, etc., also contain vitamin B2, niacin, trace amounts of vitamin B1, phosphorus, iron and other substances. It has a good tonic effect; however, during the breeding process of sea bass, saprolegniasis, enteritis, black body disease, etc. often occur, which will reduce the yield of sea bass and damage the economic interests of farmers

Embodiment 1

[0030] A kind of cultural method of perch of embodiment 1, comprises the following steps:

[0031] (1) Pond preparation: choose a place with abundant water sources, clean water and no pollution to build a pond. The pond covers an area of ​​5 acres and is rectangular. At the same time, it is equipped with a 1.5 kw aerator;

[0032] (2) Preparation before stocking: Half a month before stocking fish fry, choose a sunny afternoon to spray 50 kg of quicklime or 5 kg of bleaching powder on the dry pond for disinfection, and then inject new water into the pond. Add water quality improver to the pond water, put 2g of water quality improver per 15kg of fish, when the water quality is slightly green or slightly brown, turn on the aerator in the pond to exchange dissolved oxygen in the water;

[0033] (3) stocking of perch: select the perch fry of 4cm in length, put in 3500 tails per mu, use 3wt% salt water to rinse and disinfect the fry before going down to the pond, and put grouper in...

Abstract

The invention provides a lateolabrax japonicus aquaculture method. The method is characterized by comprising the following steps of (1) pond preparation, (2) preparation before stocking, (3) lateolabrax japonicus stocking, (4) feed feeding, (5) water quality management and (6) disease prevention management. Accordingly, in the aquaculture process, adopted synthetic feed is good in palatability, the food intake of the lateolabrax japonicus is increased, and the growth rate of the lateolabrax japonicus is increased; a disease-prevention solution sprayed every 20-30 days can effectively reduce the morbidity rate of the lateolabrax japonicus, thus the death rate of the lateolabrax japonicus is lowered, and the economic benefit of breeders is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating perch. Background technique [0002] Perch, also known as flower perch, Zhaihua, perch board, four-rib carp, is mainly distributed in the western Pacific Ocean and the coast of China, among which there are many in the Yellow Sea and Bohai Sea. Nutrients such as protein, fat, carbohydrates, etc., also contain vitamin B2, niacin, trace amounts of vitamin B1, phosphorus, iron and other substances. It has a very good tonic effect; but in the breeding process of perch, saprolegniasis, enteritis, black body disease, etc. often occur, which will lead to a decrease in the yield of perch and damage the economic interests of the breeder. Contents of the invention [0003] The present invention just aims at above technical problem, provides a kind of culture method of perch. [0004] In order to achieve the above object, the present invention adopts the foll...
