Breeding method for intermediate breeding of Anguilla marmorata fries

Abstract

The invention provides a breeding method for intermediate breeding of Anguilla marmorata fries. The breeding method comprises the steps of intermediately breeding the Anguilla marmorata fries in a cement breeding pond in the early stage and breeding the Anguilla marmorata fries in an earthen pond in the later stage. A net box and water flow boosters are arranged in the process of intermediately breeding the Anguilla marmorata fries in the cement breeding pond in the early stage, and the Anguilla marmorata fries are bred in the net box, so that the metabolites of the Anguilla marmorata fries can be conveniently filtered and deposited, the survival environment is optimized, and the breeding survival rate is increased; the four water flow boosters are arranged at the four corners of the cement breeding pond, so that water flow circulates anticlockwise, a flowing water environment is created for the Anguilla marmorata fries, Anguilla marmorata can frequently move in the flowing water environment, the bait intake speed and the growth speed of the Anguilla marmorata are increased, and the survival environment of the Anguilla marmorata is optimized; the Anguilla marmorata fries are bred for 1-2 months in the cement breeding pond and fed with blood worms in the early stage and eel powder 7 days before leaving from the pond, after the Anguilla marmorata fries are fed with the eel powder, the Anguilla marmorata fries reaching 1 g per fry are transferred into a half mu (1 mu is 1 / 6 of acre) of the earthen pond for later breeding of the Anguilla marmorata fries, and the unqualified Anguilla marmorata fries are still concentrated in the cement breeding pond and continue to be fed with the blood worms; and during the process of breeding the Anguilla marmorata fries in the earthen pond, the Anguilla marmorata fries are mainly fed with the eel powder in the early stage and occasionally fed with the blood worms, all the Anguilla marmorata fries reaching 5 g per fry are fed with the eel powder, and the Anguilla marmorata fries reaching 10 g per fry are transferred into an Anguilla marmorata growing pond for breeding.

Description

【Technical field】 [0001] The invention relates to the cultivation of flower eel seedlings, in particular to a breeding method for standard thickness cultivation of flower eel seedlings. 【Background technique】 [0002] Flower eel (Anguilla marmorata; marbled eel) is a kind of chordate, vertebrate subphylum, bony fish class, ray fin subclass, eel superorder, eel order, eel family, eel genus, also known as perch eel; the largest The individual can weigh up to 35 kg, with a body shape similar to that of an eel, with a round and blunt snout, a wide and flat interval between the eyes, slightly longer than the snout length, and wide and thick lip folds; the scales are arranged in mat-shaped scales, and the scales cross each other vertically and are buried under the skin; the lateral line is in the middle , lateral line holes are obvious; odd fins are interconnected, dorsal fin is low and long, distance between origin and anal fin origin is greater than head length; vertebrae 100-11...

AI Technical Summary

Problems solved by technology

At present, the breeding method of flower eel seedlings mostly adopts the cement pond flow mode or earth pond culture mode, the breeding density is low, the survival rate of culture is low, and the water consumption is large, and the earth pond culture mode is easy to cause the flower eel to escape; so the economic benefit of flower eel breeding is not high It is mainly reflected in the standard rough cultivation stage of seedlings. As a result, a product with high nutrition and high economic value such as flower eel has not formed a considerable scale of breeding market.
