Problems solved by technology

[0006] In view of the artificial breeding of California perch species in the prior art, the bait fed is basically all fresh fish, resulting in a high incidence of disease and a great waste of fishery resources, and the domestication and breeding of California perch is directly carried out in the pond. Due to the large pond area, resulting in Bass are difficult to concentrate on feeding, resulting in a lot of bait waste during the domestication process, low domestication success rate, irregular fish species specifications and other technical problems

Embodiment 1

[0020] 1. Pond preparation: Choose a pond close to the Yangtze River, with an area of ​​9 mu, a rectangular shape, and a depth of 2 meters. On April 20, 2016, 100 kg of quicklime per mu was used to clear the pond, and on April 27, 60 cm of water was introduced, and 60 mesh sieves were used to filter the water. On April 28, detoxify with 400 milliliters / mu of detoxification and water transfer liquid, and on April 30, use 2 kg / mu of biological fertilizer and 2 liters / mu of amino acid plus 500 grams / mu of compound algae species for fertilizer and water, and cultivate natural bait.

[0021] 2. Seed cultivation: On May 5, 770,000 artificially bred California perch fry were released, and 85,000 were released per mu. After the fry are stocked, 30 cm of water is added every other week, and 1 kg / mu of biological fertilizer is added for topdressing, so that the transparency of the pool water is kept at 30 cm, and sufficient natural bait is maintained in the pool.

Abstract

The invention belongs to the technical field of aquaculture, and discloses a method for training California perches to eat in a net cage. When a pool is cleaned and fertilized, perch fry are put in the pool. When the perch fry reach 2.5-3.0 cm, the perch fry are put in the net cage for centralized eating training, and the perch fry are fed with compound feed; regular screening and grading are conducted, and the perch fry are put into an adult fish pool for adult fish breeding after reaching a certain size. According to the method for training the California perches to eat in the net cage, the success rate of fingerling taming and the survival rate are high, the fingerlings are standardized in size, feed waste is reduced, and the economic benefits of the aquaculture are increased.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of aquatic animal breeding, and in particular relates to a method for domesticating California perch species in net cages. [0003] Background technique: [0004] California perch, also known as largemouth bass, is a ferocious freshwater carnivorous fish that basically grows wild in rivers and lakes. It is expensive because of its delicious meat and extremely scarce quantity. Artificial breeding has been started for more than ten years, but because the bait is basically all chilled fish, the incidence of the disease is extremely high, and the waste of fishery resources is huge. It is a restricted breeding method in the country. Therefore need to provide a kind of new California perch training breeding method, the present invention carries out net cage concentrated food to California perch species, makes it ingest compound feed, domestication success rate is high, improved survival rate, reduced enviro...
