Embodiment 1

[0012] Step 1. Select the species of loach, start selection in late April, the specific standard is that the length of female loach is ≥15cm, the weight of a single tail is ≥20g, the abdomen is swollen and pink, and the eggs in the abdomen can be vaguely seen; the length of male loach is ≥10cm , single tail weight ≥ 7 ~ 10g, according to the above standard, the selected species of loach were put into the cages respectively, and hatching and breeding began when the water temperature reached 18°C ​​at the end of April;

[0013] Step 2. Artificially induce labor, inject oxytocin hormone to the seed loach, specific injection: 0.2 ml per female loach, 0.1 ml per male loach, inject from the back of the seed loach to the head at an angle of 45°, and the injection depth It is 0.2cm, and the seed loach after injection is put into net cage immediately and waits to be produced;

[0014] Step 3, artificial dry insemination, when the estrus signs appear in the species of loach, the artific...

Abstract

The invention provides a breeding method of Taiwan loaches. The method comprises the following steps: firstly, selecting loaches, the female loach being greater than or equal to 15 cm in length, one tail being greater than or equal to 20 g in weight, male loach being greater than or equal to 10 cm in length and one tail being greater than or equal to 7 to 10 g in weight, at last ten-day of April, then respectively putting the selected loaches into mesh cages, performing incubation culture with the water temperature being 18 DEG C, secondly, injecting oxytocic hormone 0.2 milliliters for each female loach and 0.1 milliliter for each male loach from the back to the head at the angle of inclination of 45 degree, with the needling depth being 0.2 cm, then putting the loaches into the mesh cages for awaiting delivery, thirdly, adopting a dry method of artificial fertilization, taking away the loaches, incubating fertile eggs in the condition of slow flowing water, with the water temperature being 22 to 25 DEG C, and fourthly, transferring young loaches into a pool with good water quality for breeding after young loaches are hatched for three days, ensuring that breeding material adopts cooked egg yolk, and respectively putting the loaches into the pool according to different sizes, with a standard that 100 to 150 loaches with the length being 5 to 6 cm are put into each square meter of water and 50 to 80 loaches with the length being 7 to 8 cm are put into each square meter of water. The method is scientific and reasonable during the whole process, meets the living habit of Taiwan loaches, and can improve the breeding reliability and increase the survival rate.

Description

technical field [0001] The invention relates to a method for breeding loach, in particular to a method for breeding loach from Taiwan. Background technique [0002] Loach is a kind of aquatic product with delicious taste and high nutritional value, and Taiwan loach has more market competitiveness in terms of taste and nutrition, especially the short growth period, fast growth speed and high yield have significant economic advantages, but Taiwan loach is due to Because of the particular geographical location and climatic conditions, it is very difficult to breed and develop in the mainland. The main reason is that the reliability of breeding and the survival rate are not ideal due to changes in geographical and climatic conditions, making it impossible to form large-scale breeding, which directly affects economic benefits. Contents of the invention [0003] The purpose of the present invention is to solve the above problems of low breeding survival rate and inability to mee...
