Problems solved by technology

[0003] However, in the breeding methods of Taiwan loach currently adopted, the reproduction speed of Taiwan loach is relatively slow, and the hatching survival rate is not very high. Therefore, in the breeding of Taiwan loach, a better breeding method still needs to be explored to improve the growth rate of Taiwan loach. Reproduction rate and hatch survival rate

Embodiment 1

[0033] A kind of efficient factory breeding method of Taiwan loach, comprises the steps:

[0034] (1) Select pro loach

[0035] Choose a healthy parent loach with strong physique, bright body color, correct body shape, strong vitality, no disease or injury, and complete fin rays. The male parent loach requires a body length of 10-15cm and a weight of 10-15g, and the female parent loach has a body length of 12-18cm. , weighing 30-35g.

[0036] (2) Cultivation of parent loach

[0037] After disinfecting the breeding pool, put the female loach and the male loach separately into the breeding pool for flushing cultivation. The breeding pool requires abundant water, fresh water quality and no pollution. The cultivation time is 25 days, and 15 cm of clay is laid on the bottom of the pool. The ratio of the female loach to the male loach is 1:2, the stocking density is 120Kg per mu, and the parent loach is fed with feed every day, twice a day, and the amount of each feeding is 5% of ...

Embodiment 2

[0049] A kind of efficient factory breeding method of Taiwan loach, comprises the steps:

[0050] (1) Select pro loach

[0051] Choose a healthy parent loach with strong physique, bright body color, correct body shape, strong vitality, no disease or injury, and complete fin rays. The male parent loach requires a body length of 15-18cm and a weight of 15-25g, and the female parent loach has a body length of 18-25cm. , weighing 35-45g.

[0052] (2) Cultivation of parent loach

[0053] After disinfecting the breeding pool, put the female loach and the male loach separately into the breeding pool for flushing cultivation. The breeding pool requires sufficient water source, fresh water quality and no pollution. The cultivation time is 30 days, and 20 cm of clay is laid on the bottom of the pool. The ratio of the female loach to the male loach is 1:4, the stocking density is 200Kg per mu, and the parent loach is fed with feed every day, twice a day, and the amount of each feeding is...

Embodiment 3

[0065] A kind of efficient factory breeding method of Taiwan loach, comprises the steps:

[0066] (1) Select pro loach

[0067] Choose a healthy parent loach with strong physique, bright body color, correct body shape, strong vitality, no disease or injury, and complete fin rays. The male parent loach requires a body length of 12-16cm and a weight of 12-20g, and the female parent loach has a body length of 15-22cm. , weighing 32-40g.

[0068] (2) Cultivation of parent loach

[0069] After disinfecting the breeding pool, put the female loach and the male loach separately into the breeding pool for flushing cultivation. The breeding pool requires sufficient water source, fresh water quality and no pollution. The cultivation time is 28 days, and 16 cm of clay is laid on the bottom of the pool. The ratio of the female loach to the male loach is 1:3, the stocking density is 150Kg per mu, and the parent loach is fed with feed every day, twice a day, and the amount of each feeding ...

Abstract

The invention discloses a high-efficiency factory propagation method of Taiwan misgurnus anguillicaudatus, and belongs to the technical field of misgurnus anguillicaudatus propagation. The high-efficiency factory propagation method of the Taiwan misgurnus anguillicaudatus comprises the following steps: 1) selecting parent misgurnus anguillicaudatus; 2) cultivating the parent misgurnus anguillicaudatus; 3) carrying out injection for spawning induction; 4) carrying out artificial insemination; 5) carrying out hatching; and 6) breeding fry. According to the high-efficiency factory propagation method provided by the invention, through the throwing of male and female parent misgurnus anguillicaudatus with a proper proportion, proper breeding density, adoption of self-made breeding feed, and control of the water flow rate and oxygen flow rate in a hatching tank, and the like, the propagation speed and the hatching survival rate of the Taiwan misgurnus anguillicaudatus are greatly improved, and high-efficiency large-scale propagation of the Taiwan misgurnus anguillicaudatus is facilitated.

Description

technical field [0001] The invention relates to the technical field of loach breeding, in particular to a high-efficiency factory breeding method for Taiwan loach. Background technique [0002] Taiwan loach belongs to the family Loach family Paraloach and is a kind of large scale paraloach, commonly known as the big loach. This kind of loach has been cultivated artificially for many years, and it is the loach most suitable for the artificial breeding environment in my country. The large-scale breeding of this loach in Guangdong, Guangxi, Fujian and other places has proved that the seedlings bred by this loach can reach a single size of about 100 grams in that year, and it is currently a more competitive loach species. Since it was introduced into our country, because of its fast growth, tender meat, delicious taste and rich nutrition, it is one of the first choice fish species for tonic in winter. Therefore, there are more and more breeders and higher economic benefits. ...
