Problems solved by technology

Lip carp grows slowly under natural conditions. In recent years, due to the development of cascade hydropower stations in the Beipan River Basin, especially the construction and development of some water conservancy projects, the natural breeding and spawning sites of lip carp have been seriously damaged. In particular, the construction of some water conservancy projects has destroyed the original spawning grounds of rohu, resulting in a low natural yield in the Pearl River Basin, and a devastating blow to the resources of rohu in the original place. endangered

Embodiment 1

[0018] A method for artificial domestication and cultivation of lip carp, comprising the following steps:

[0019] (1) Construction of mud carp breeding ponds: construction of flowing water cultivation ponds artificially simulating the natural environment, with an area of ​​60 square meters, a water depth of 0.6-0.8m, a water velocity of 0.1-0.2m / s, and a water body with a pH of 7.0- 8.0, the dissolved oxygen is greater than 6mg / L, the annual water temperature is between 18 and 25°C, and the water source is the flowing water breeding pond of the Huangguoshu Rainbow Trout Breeding Farm.

[0020] (2) Selection of broodstock fry: Screen the wild-caught lip carp, select healthy, disease-free, larger individuals, and better-developed lip carp as breeding objects, and soak and disinfect the selected lip carp;

[0021] (3) Diet transformation: put bait into the cultivation pond for artificial food habit domestication. Within one month before the domestication, use egg yolk and soybea...

Embodiment 2

[0026] A method for artificial domestication and cultivation of lip carp, comprising the following steps:

[0027] (1) Construction of mud carp breeding pond: build a micro-flow water cultivation pond artificially simulating the natural environment. The micro-flow water cultivation pond has an area of ​​500 square meters, a water depth of 0.5-0.6m, a water velocity of 0.5-0.15m / s, and a water body with a pH of 7. 0~8.5, dissolved oxygen is greater than 5mg / L, annual water temperature is between 18~25℃, the water source is the flowing water breeding pond of Huangguoshu Rainbow Trout Breeding Farm, which is clear and pollution-free, and the water quality is good, which meets the basic growth conditions of lip carp;

[0028] (2) Selection of broodstock fry: Screen the wild-caught lip carp, select healthy, disease-free, larger individuals, and better-developed lip carp as breeding objects, and soak and disinfect the selected lip carp;

[0029] (3) Diet transformation: Put bait int...

Abstract

The invention relates to a method for artificial domestication and cultivation of semilabeo notabilis. The method comprises the steps of 1, building a semilabeo notabilis cultivation pond; 2, collecting and selecting parent fish fry; 3, conducting food habit conversion; 4, conducting artificial domestication of fry; 5, observing gonad development; 6, conducting domestication management. By the adoption of the method, massive cultivation and population continuation of semilabeo notabilis are facilitated, native commercial fish aquaculture and new species are added, ecological balance of a water area is maintained, local native fish resources are protected, population quantity is increased, biodiversity and ecological balance are maintained, and conditions are provided for semilabeo notabilis cultivation and considerable economic benefits are obtained by means of the natural resources in the Dabang river drainage basin.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for artificially domesticating and cultivating mud carp. Background technique [0002] Lip carp ( Semilabeo notabilis Peters ) belonging to Cyprinidae ( Cypriniformes ), Cyprinidae ( Cyprinidae ), Rohu subfamily ( Labeoninae ), Lip carp ( Semilabeo P ), commonly known as round shad, no six fish, different fish, etc., is one of the precious economic fish in the Pearl River system. Mud carp is a fish in the middle and lower layers of rivers. It likes running water and often goes upstream. Fishermen call it "only enter the water, never fall into the water", so it is called "the fish that has not fallen". [0003] The Beipan River is a major tributary of the Hongshui River, the upper source of the Xijiang River in the Pearl River Basin. It originates at the northwestern foot of Maxiong Mountain in the Wumeng Mountains, Zhanyi County, Yunnan Province,...
