Artificial breeding technology of brachymystax lenok

Abstract

The invention discloses an artificial breeding technology of brachymystax lenok and relates to the technical field of breeding of brachymystax lenok. The artificial breeding technology of the brachymystax lenok comprises steps as follows: 1, parent fish breeding; 2, artificial breeding; 3, postpartum treatment of parent fish; the minimum sexual maturity age of male wild brachymystax lenok is 4 years, the minimum sexual maturity age of female wild brachymystax lenok is 5 years, the brachymystax lenok at the age of 5 years old or younger has no egg laying behavior under the artificial breeding condition, the captured wild parent fish can perform breeding after completely adapting to man-made environment when the captured wild parent fish is domesticated and bred for at least one year, a flowing water cement pond is adopted as the parent fish breeding pond, and 4-5 pairs of brachymystax lenok are bred in every 10 m<2> of the flowing water cement pond. The delivery and breeding environmentof the brachymystax lenok is controlled through artificial breeding, so that female and male fish grow basically synchronously, smooth artificial breeding is guaranteed, the insemination success rateof the brachymystax lenok is increased, the growth and survival rate of the bred fish is increased, the death rate is greatly reduced, and thus, the artificial breeding effect of the brachymystax lenok is improved.

Description

technical field [0001] The invention relates to the technical field of lemur salmon cultivation, in particular to the artificial breeding technology of lemur salmon. Background technique [0002] Thin scale salmon is named for its tiny scales. It belongs to the order Salmonformes, Salmonidae, and Lepidoptera. Commonly known as: mountain fine scale fish, river fine scale fish, Lu fish, Lu flower fish, golden board fish, flower fish, plum blossom fish and small red fish. [0003] The body shape of lentils is medium-sized, slightly spindle-shaped, slightly flattened, with a body length of 17-45 cm, a weight of 0.5-1.5 kg, and the largest individual can reach 6-8 kg. The snout is blunt, slightly protruding, the upper jaw is slightly longer than the lower jaw, the mouth is small, at the front of the body, the position is low, the mouth cleft reaches the center of the eye, the lip is thick, the maxilla is wide and exposed, the back end reaches below the center of the eye, the ey...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides the artificial breeding technology of lentil salmon, which solves the problem of high mortality in the breeding process of lentil salmon, and the seedling breeding technology of other fishes is too cumbersome and difficult to popularize. It is applicable to the problem of cultivating lemur seedlings, and provides a method for cultivating lentinus seedlings
