Embodiment 1

[0016] A kind of method that adopts multivariate compound feed to breed red-tailed crown, comprises the following steps:

[0017] Cultivation facilities: square pond with flat bottom, less silt, 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 the water quality lean, with a pH of 7.8, fewer types and quantities of zooplankton, and 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 purpose of keeping the water quality fresh for a long time. Put some tiles or stones at the bottom of the tank, keep the water temperature at 26 ℃ ~ 28 ℃, and the pH at 6 ...

Embodiment 2

[0022] The preparation method is the same as in Example 1.

[0023] At the juvenile stage of the red-tailed crown of growth, pull it out, and divide it into five pools, 500 in every pool, put in the microbial red-tailed crown of the present invention according to the dosage of 200kg per mu in the four pools fertilizer and common redtail crown fertilizer (control 1, produced from Beijing Century Arms Biotechnology Co., Ltd. ), and the other pond did not put in the red tail crown fertilizer (control 2), but put in the same amount of common fish food, the rest of the feeding amount was the same, and the cultivation environment was the same. After 2-4 months of breeding, its output was compared with that of red tail. The growth status of the crown is specifically shown in Table 1 and Table 2:

[0024]

[0025]

[0026] Through the comparison of table 1 and table 2, it can be found that adding the compound microbial fertilizer of the present invention can p...

Abstract

A method for cultivating the green terror by multi-element compound feed includes the steps of selecting a cultivation facility, namely a square pond, which is averagely 0.8m in water depth, with flat bed and little mud and convenience in irrigation and drainage; sterilizing with 10mg / L trichloroisocyanuric acid 10 days before the advanced fry are put in the pond; keeping lean water, with 7.8pH, allowing fertilized eggs to hatch into the fry for 2-3 days; adding the multi-element compound feed after 5-6 days. Addition of the multi-element compound feed can promote the green terror to grow fast, with higher EPA content and less diseases, while fewer green terror fishes die of diseases; in addition, more beneficial microorganisms occur in the water, and final quality and mass are increased.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating red-tailed crowns by using multi-component compound feed. Background technique [0002] The red-tailed crown (Aequidens rivulatus) belongs to the Cichlidae family. It is a relatively large ornamental fish. The adult fish is up to 25 cm long. It is native to South America. The body length of male fish can reach about 20 cm, and the individual of female fish is smaller. The dorsal fin of this fish is very long, extending from the rear edge of the gill cover to the front of the caudal peduncle. The caudal and dorsal fin edges of sexually mature individuals are golden yellow or red, hence the name. There are bright green stripes on the lower part of the gill cover, so it is also called Green Terror. The red-tailed crown fish has a ferocious temperament. The juvenile fish feed on zooplankton, and they can swallow small fish and shrimps when they grow up. Before sexu...
