Problems solved by technology

However, there is a huge gap in the number of large-sized fish species with a size of 10-15 cm in the season in the northern region, and it is "difficult to find one seedling", and the price is high, which cannot meet the needs of breeding
Therefore, if we can develop the breeding technolo

Embodiment 1

[0024] The off-season breeding method of California perch species, the specific steps are as follows:

[0025] S1 pond preparation

[0026] The area of ​​the pond used for water flower cultivation is 5 mu. After draining the pond water, remove the excess silt. The thickness of the silt in the pond is kept at about 10 cm. After 7 days, water was injected into the pond, and the water was filtered into the pond with a 60-mesh sieve during the water injection. The water injection depth was 1 m, and a 10 m×8 m×1.2 m cage was set in the pond with a 60-mesh polyethylene mesh. 2 cages.

[0027] Cage cultivation of California perch

[0028] On August 25, 2019, 1 million California perch flowers were purchased from Wujiang District, Suzhou. After the water flowers arrived, the fry and the fry bags were placed in the pond cage for 12 minutes, so that the water temperature in the bag was consistent with the pond water temperature, and then put Splashes are put from bags into cages. On...

Embodiment 2

[0039] The off-season breeding method of California perch species, the specific steps are as follows:

[0040] S1 pond preparation

[0041] The area of ​​the pond used for water flower cultivation is 7 mu. After the pond water is drained, excess silt is removed. The thickness of the silt in the pond is kept at about 10 cm. After 10 days, water was injected into the pond, and the water was filtered into the pond with a 60-mesh sieve during the water injection. The water injection depth was 1 m, and a 10 m×8 m×1.2 m net cage was set in the pond with a 60-mesh polyethylene mesh. 2 cages.

[0042] Cage cultivation of California perch

[0043] On August 25, 2019, 1.2 million California perch were purchased from Wujiang District, Suzhou. After the water flower arrived, the fry and the fry bag were placed in the pond cage for 15 minutes, so that the water temperature in the bag was consistent with the pond water temperature. Splashes are put from bags into cages. One day after the ...

Embodiment 3

[0054] The off-season breeding method of California perch species, the specific steps are as follows:

[0055] S1 pond preparation

[0056] The area of ​​the pond used for water flower cultivation is 8 mu. After the pond water is drained, excess silt is removed. The thickness of the silt in the pond is kept at about 10 cm. After 10 days, water was injected into the pond, and the water was filtered into the pond with a 60-mesh sieve during the water injection. The water injection depth was 1 m, and a 10 m×8 m×1.2 m net cage was set in the pond with a 60-mesh polyethylene mesh. 2 cages.

[0057] Cage cultivation of California perch

[0058] On August 25, 2019, 1.2 million California perch were purchased from Wujiang District, Suzhou. After the water flower arrived, the fry and the fry bag were placed in the pond cage for 18 minutes, so that the water temperature in the bag was consistent with the pond water temperature. Splashes are put from bags into cages. One day after th...

Abstract

The invention discloses a micropterus salmoides fingerling out-of-season cultivation method which comprises the following steps: S1, pond preparation: the area of a pond is 5-8 mu and after pond wateris drained, the thickness of sludge in the pond is kept at 8-12 cm, about 5-15 cm of accumulated water is left in the pond, quick lime is used for cleaning the pond at 100-150 Kg/mu, and after 7-14 days, water is injected into the pond, the water injection depth is 0.8-1.8 m, and a net cage is arranged in the pond. The micropterus salmoides SHUIHUA in autumn are cultured through the net cages, and the survival rate of the SHUIHUA can be effectively increased; secondly, the bait utilization rate can be increased through cultivation in a cement pond, and the fry physique is effectively enhanced; finally, proper growth temperature is provided for the fish fries in winter through a greenhouse and a boiler temperature control technology, and therefore it is guaranteed that the fish fries are kept in a rapid growth state all the time to be cultured into large-size fish fries. The micropterus salmoides large-size fingerling out-of-season breeding technology provides technical support for production of micropterus salmoides large-size fingerlings, and meanwhile has great significance in promoting transformation and upgrading of micropterus salmoides breeding modes in northern areas.

Description

technical field [0001] The invention belongs to the technical field of fish species cultivation in aquaculture, and in particular relates to a method for off-season cultivation of large-scale California perch species. Background technique [0002] California perch scientific name largemouth bass ( Micropterus salmoides ), belonging to the order Perciformes, the family Sunfish, and the genus Black Perch. It is native to the Mississippi River system in California, USA. It was introduced into my country from Guangdong Province in 1983 to carry out breeding experiments, and it was successfully artificially propagated in 1985. Because of its tender meat, delicious taste, no intermuscular thorns, fast growth, easy to catch, wide temperature tolerance and strong disease resistance, it has gradually been recognized by consumers and farmers and has become a valuable economic fish. At present, domestic California perch farming is concentrated in southern provinces such as Guangdong, ...
