Abstract

The invention provides a method for artificial propagation of soft-finned lobster, which belongs to the technical field of aquaculture. Put the female broodstock and male broodstock in the breeding pond for broodstock breeding. The environmental parameters of the cultivation pond are as follows: the flow rate of water flow is 30-45m / min, the water quality transparency is 90-100cm, the dissolved oxygen in water is 6.2-7.5mg / L, and the water pH value is 7.2 ~7.8, the water temperature is 16~25℃, and the photoperiod is 9~12h; during the breeding period of the broodstock, the shading treatment is carried out on the breeding pond, and the pellet feed is fed twice a day; eggs and sperm are collected from the broodstock, artificially inseminated, hatched, After breeding, the soft-finned new light lip fish was obtained. The invention avoids the use of oxytocic agents in the broodstock breeding process, not only can naturally lay eggs and produce sperm, but also can obtain a higher fertilization rate. At the same time, the successful cultivation of the broodstock of the soft-finned L. chinensis has fundamentally solved the problem of male and female agenesis or asynchronous development of wild fish in the pond culture environment.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for artificial reproduction of soft-finned new light lip fish. Background technique [0002] Neolissochilus benasi belongs to the order Cypriniforms, Cyprinidae, Barbinae, Neolissochilus, also known as flower fish. Historically, the soft-finned Xinguang lip fish was the main target of fishermen in the Yuanjiang River Basin. The individual can reach up to 25 kilograms. It is a large economic fish. It is mainly distributed in Hekou, Jiangcheng, Xichou, Yuanjiang and other places in Yunnan. in Vietnam. Because of its gorgeous appearance, the soft-finned sunbeam, also known as the golden giro, has great potential in the ornamental fish market. Therefore, the soft-fin sunbeam has great development potential for both edible and ornamental purposes. [0003] In recent years, due to the high fishing intensity, the development of cascade power stations, and the ...
