A kind of breeding method of broodstock of Yarkand plateau loach

Abstract

The invention discloses a method for culturing triplophysa yarkandensis parents. The method comprises the steps of selecting and culturing triplophysa yarkandensis adults and selecting and culturing the triplophysa yarkandensis parents, wherein during adult culture, the triplophysa yarkandensis adults are cultivated in an indoor flowing water tank, the culture cycle is about 7-12 months, the flow rate of the flowing water tank is kept at 30-50s / L, the depth of water is 15-25cm, floating feed, in which the content of protein is higher than 25%, is fed 2-5 times respectively in the morning and night, and the amount of fed feed is 5-15%; during parent culture, the triplophysa yarkandensis parents are fed with floating feed, in which the content of protein is higher than 30%, in a flowing water tank, the amount of fed feed is 5-20%, and the sex glands of the triplophysa yarkandensis parents are mature through culturing till March to June of the coming year. Through culturing triplophysa yarkandensis according to the method, the condition that over 80% of individuals reach sexual maturity at concentrated time and complete concentrated spawning can be guaranteed, so that artificial induced spawning and fertilization are carried out successfully, the offspring propagation of the triplophysa yarkandensis is guaranteed, and the populations of the triplophysa yarkandensis are guaranteed.

Description

technical field [0001] The invention relates to the production field of Yarkand plateau loach, in particular to a method for cultivating broodstock of Yarkand plateau loach. Background technique [0002] Due to the small size of the Yarkand plateau loach, it is difficult for the individuals caught in the wild water to survive, the sperm motility is small, and the number of fecundity eggs is small, so the caught wild individuals cannot guarantee the effective reproduction of offspring and the significance of the population. At present, there is also artificial cultivation of Yarkand plateau loach, such as in ponds or cement ponds, but it is found through experiments that the results are not ideal; in ponds, due to the relatively stable water ecosystem, for the Tarim Basin, , the temperature in summer is too high to provide suitable water temperature of about 20°C for the Yarkand plateau loach.

AI Technical Summary

Problems solved by technology

[0002] Due to the small size of the Yarkand plateau loach, it is difficult for the individuals caught in the wild water to survive, the sperm motility is small, and the number of eggs is small, so the caught wild individuals cannot guarantee effective reproduction and the significance of the population.

At present, there is also artificial cultivation of Yarkand plateau loach, such as in ponds or cement ponds, but it is found through experiments that the results are not ideal; in ponds, due to the relatively stable water ecosystem, for the Tarim Basin, , the temperature in summer is too high to provide suitable water temperature of about 20°C for the Yarkand plateau loach. Effect

In the cement pool, the area is small, it can be observed, and it is easy to domesticate, and can produce micro-flow water, but the minimum diameter of the cement pool is 2m, the depth is 1.5m, the water storage capacity is too large, the exchange rate is too fast, the cost is too high, and it is difficult to catch fish.
