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 for limiting the protection scope of the present invention.

[0015] Nurturing facilities:

[0016] The square pond has a flat bottom, less silt, convenient irrigation and drainage, an area of ​​about 166 m2, and an average water depth of 0.8 m. 10 days before the fingerlings are placed in the pond, disinfect with 10 mg / L strong chloroquine. Keep the water lean, with a pH of 7. 8. There are few types and numbers of zooplankton, and there are aquatic plants around the pond. The pond is equipped with a water purification system, including coral stones, filter cotton, activated carbon, etc. Using micro-pumps to circulate the water can not only purify the water quality but also increase the dissolved oxygen in the water body to achieve the purpose of keeping the water fres...

Abstract

An artificial fry rearing method for Aequidens rivulatus includes the steps of setting a rearing facility, namely a square pond with flat bed, little mud and average water depth of 0.8m and convenient for irrigation and drainage; sterilizing the pond with 10mg / L trichloroisocyanuric acid 10 days before the fry is put in the pond; keeping the water thin under the pH of 7.8, allowing fertilized eggs to hatch into fry for 2-3 days, which can freely swim and feed around after 5-6 days, and initially feeding the fry with fairy shrimp or small water flea four times a day; feeding with Daphnia (cladocerans) after half of a month; feeding with artificial mixed feed, which can also be made from fresh meat, shrimp meat and snail meat, one month later, preferably the feed with high protein content; generally feeding with animal feed in the mating season to improve nutrition and promote gonad development of parent fishes.

Description

technical field [0001] The invention relates to a method for aquaculture, in particular to a method for cultivating artificial seedlings of red-tailed crown. Background technique [0002] The red-tailed crown (Aequidens rivulatus) belongs to the cichlid family. It is a relatively large ornamental fish with an adult body up to 25 cm. The male fish can be up to 20 cm in length, and the female fish is smaller. The dorsal fin of the fish is very long, extending from the rear edge of the operculum to the front of the caudal peduncle. The edges of the caudal and dorsal fins of sexually mature individuals are golden or red, hence the name. The lower half of the gill cover has bright green stripes, so it is also called Green Terror. The red-tailed crown fish has a ferocious temperament. The juveniles feed on zooplankton, and when they grow up, they can swallow small fish and shrimp. Before sexual maturity, the species can get along well within the species, and after sexual maturi...
