Embodiment 1

[0031] A hatching method for Taiwan loach, comprising the steps:

[0032] (1) Select pro loach

[0033] 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.

[0034] (2) Cultivation of parent loach

[0035] 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 the body weight of the p...

Embodiment 2

[0046] A hatching method for Taiwan loach, comprising the steps:

[0047] (1) Select pro loach

[0048] 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 15-20g, and the female parent loach has a body length of 18-25cm. , weighing 35-40g.

[0049] (2) Cultivation of parent loach

[0050] 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 8% of the body weight o...

Embodiment 3

[0061] A hatching method for Taiwan loach, comprising the steps:

[0062] (1) Select pro loach

[0063] 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 20-25g, and the female parent loach has a body length of 15-22cm. , weighing 40-45g.

[0064] (2) Cultivation of parent loach

[0065] 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 is 6% of the body weight...

Abstract

The invention discloses a hatching method of Taiwan misgurnus anguillicaudatus, and belongs to the technical field of misgurnus anguillicaudatus hatching. The hatching 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; and 5) carrying out hatching. According to the hatching 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 hatching rateof the Taiwan misgurnus anguillicaudatus is greatly improved, and fry with robust body type are obtained.

Description

technical field [0001] The invention relates to the technical field of loach hatching, in particular to a method for hatching loach from Taiwan. 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. [0003] Yet in the h...
