Embodiment Construction

[0011] 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.

[0012] A method for cultivating artificial seedlings of Corona roxa using nano-added feed

[0013] 5) 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 i...

Abstract

The invention discloses a method for breeding artificial aeguidens rivulatus fries by nano feeds. The method comprises the following steps: selecting a breeding facility, namely a square pond with the characteristics of flat bottom, less sludge, convenience in irrigation and drainage and average water depth of 0.8m; disinfecting the pond by 10mg / L of trichloroisocyanuric acid in 10 days before aeguidens rivulatus is put into the pond; keeping clear water and the pH value to be 7.8, wherein aeguidens rivulatus fries are hatched out by fertilized ova after 2-3 days and can freely move for finding foods in another 5-6 days; feeding the aeguidens rivulatus fries with fairy shrimps or small water fleas for four times each day in the beginning; after half a month, feeding the aeguidens rivulatus fries with blood worms (cladocerans); after a month, feeding the aeguidens rivulatus fries with artificial compound feeds, optimally selecting and using feeds with high protein content such as fresh fish meat, shrimp meat and snail meat, also selecting and using compound feeds, and generally feeding the aeguidens rivulatus fries with animal feeds for improving the nutrition and promoting the gonad development of parent fishes in a breeding season.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating artificial seedlings of Corona roxa by adopting nano-added 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. Befo...
