Embodiment

[0024] A kind of artificial breeding method of tall barb comprises the following steps:

[0025] (1) Broodstock selection:

[0026] The parents are collected from the wild in the Lancang River and bred through domestication selection. The advantage of growth speed is obvious in the population obtained from the wild parent, and the broodstock is cultivated and used as the broodstock.

[0027] (2) Breeding of broodstock:

[0028] 1) Construction of breeding pool: Broodstock breeding pool should be located in a place with sufficient water source, fresh water quality, convenient drainage and quiet environment. The bottom of the pool is flat, with less silt, the area is 0.2h㎡-0.33h㎡, and the water depth is 1.5m-2m. Pond cleaning complies with SC / T1008-2002.

[0029] 2) Ratio of male to female and stocking amount: The ratio of male to female is 1:1; the stocking amount of broodstock is about 55kg / 100㎡ or the stocking density is 100-120 / 100㎡. Appropriate amount can be matched wi...

Abstract

The invention discloses an artificial propagation method for barbodes pierrei. The artificial propagation method comprises the steps of parent fish selection, parent fish rearing, artificial propagation and incubation. A scientific artificial breeding method is adopted to cultivate the artificial propagation, the fertilization rate and the hatching rate are high, and the problem that the number of wild barbodes pierrei is sharply decreased due to excessive fishing for the economic purpose is solved. The breakthrough of artificial propagation of the barbodes pierrei growing out of nothing is realized.

Description

technical field [0001] The invention belongs to the technical field of artificial reproduction of fish, and in particular relates to an artificial reproduction method of the tall carp. Background technique [0002] tall barb, Barbodes pierrei (Sauvage, 1880), a species of fish of the genus Cyprinidae. The side of the body is flat, the back is raised, and the fish body is slightly diamond-shaped. The head is short and slightly triangular, with 2 pairs of whiskers and large scales. It is mainly distributed in the fresh waters of southeast Asia in Yunnan, and can be seen in rivers in the southwest of Taiwan. [0003] The body length is 2.3-2.7 times the body height, 3.6-3.9 times the head length, 6.2-7.7 times the caudal peduncle length, and 6.3-6.6 times the caudal peduncle height. The head length is 3.0-4.0 times the snout length, 2.4-3.4 times the eye diameter, and 2.4-2.8 times the eye distance. The length of the caudal peduncle is 0.8-1.0 times the height of the caud...
