Embodiment Construction

[0014] The preferred embodiments of the present invention will be described in detail below; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0015] Breeding facilities:

[0016] A square pond with a flat bottom, less silt, and convenient drainage and irrigation, with an area of ​​about 166 m2 and an average water depth of 0.8 m. Ten days before the fish species are put into the pond, they are disinfected with 10 mg / L strong chlorine. Keep water quality lean, pH 7. 8. The species and quantity of zooplankton are small, and there are aquatic plants growing around the pond. The pond is equipped with a water purification system, including coral stone, filter cotton, activated carbon, etc. Use micro-pumps to circulate the water, which can not only purify the water quality but also increase the dissolved oxygen in the water body, so as to achieve the purpos...

Abstract

A method for cultivating artificial seedlings of Crown of the Red Tail, comprising the steps of: cultivating facilities: a square pond with a flat bottom, less silt, convenient drainage and irrigation, and an average water depth of 0.8m. 10 days before the fish species are put into the pond, they are disinfected with 10mg / L strong chlorine essence. Keep the water quality lean and the pH is 7.8. The fertilized eggs hatch in the pond for 2~3 days and the larvae can swim freely and look for food everywhere after 5~6 days. At first, feed Artemia or small daphnia four times a day After half a month, you can feed red worms (Cladocera); after one month, you can feed artificial compound feed, preferably feed with higher protein content: fresh fish, shrimp, snail meat, you can also ingest compound feed, and it will help you in breeding. During the season, in order to strengthen nutrition and promote the gonad development of broodstock, animal feed is usually fed.
