Embodiment

[0020] A kind of artificial reproduction method of scalefish, comprises the following steps:

[0021] (1) Broodstock selection:

[0022] The parents are collected from the wild in the Lancang River and bred through domestication selection. Select healthy and complete scales from wild parent populations, and cultivate broodstock for use as broodstock.

[0023] (2) Breeding of broodstock:

[0024] 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.

[0025] 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 50kg / 100㎡ or the stocking density is 7 to 9 tails / 100㎡. Appropriate amount can be matched with stocking carnivorous fish...

Abstract

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

Description

technical field [0001] The invention belongs to the technical field of artificial propagation of fish, and in particular relates to an artificial propagation method of lepidocarpus. Background technique [0002] The squamous knot fish is flat on the side, with a pointed snout and protruding. The mouth is inferior, the lip is thick and fleshy, completely covering the edge of the jaw; the lower lip is divided into 3 lobes, the middle lobe is developed, and it is tongue-shaped, and the rear edge of the middle lobe is almost level with the corner of the mouth in adult fish. 2 pairs of barbels, snout barbels short, behind maxillary barbels extending to posterior edge of eyes. The scales are large, with 23-26 scales on the lateral line, and the lateral line is slightly curved. The hard spines of the dorsal fin are thick and smooth, and the caudal fin is forked. Distributed in the Lancang River and Nujiang River systems in Xishuangbanna, Yunnan Province. It lives in places wher...
