Problems solved by technology

Before that, I checked the history, although there were some articles about the basic biological research of wild Xianghua mud carp, but I never saw a report about the artificial domestication and breeding of Xianghua mud carp

Embodiment 1

[0012] (1) Choose a site to build a pool. A cement pond was built in the near-water area downstream of the reservoir as an acclimation pond. The domestication pool is a brick-concrete structure, which is rectangular. The pool depth is 1.4m, and the water surface area is 12×3m 2 . On both sides of the pond wall, asbestos tiles are used to set up a awning for the pond fish to hide and inhabit. The bottom surface of the pool is inclined from the inlet end to the drainage end to form a uniform slope, so that the water inlet and drainage are smooth. The water from the reservoir is then diverted into the pool to form a flowing water pool, maintaining a micro-flowing water state with a flow rate of 0.1m / s, a transparency of 70cm, and a dissolved oxygen content of 6-9mg / L. And use conventional water purification measures to purify water sources to ensure good water quality;

Embodiment 2

[0018] (1) Choose a site to build a pool. A cement pond was built in the near-water area downstream of the dam as an acclimation pond. The domestication pool is a brick-concrete structure with an oval shape. The pool depth is 1.5m and the water surface area is 60m 2 . 10 prefabricated panels are used on both sides of the pool walls to build one with an area of ​​2m 2 The cave-like shade provides shelter for pond fish. The bottom surface of the pool is inclined from the inlet end to the drainage end to form a uniform slope, so that the water inlet and drainage are smooth, and then the water from the dam is drawn into the pool to form a flowing pool, maintaining the state of micro-flowing water, with a flow rate of 0.2m / s, a transparency of 80cm, and dissolved Oxygen content 6 ~ 9mg / L. Conventional water purification measures are used to purify water sources to ensure good water quality;

Abstract

The invention discloses a method for inducing and domesticating wild Sinilabeo decorus tungtings, which comprises the following steps of selecting a site for building a pit, collecting wild Sinilabeo decorus tungtings, mixing and culturing the wild Sinilabeo decorus tungtings, casting feed and inducing and domesticating the wild Sinilabeo decorus tungtings. The invention domesticates the wild Sinilabeo decorus tungtings under the discharge condition of the cement pit, enables the wild Sinilabeo decorus tungtings to reach a live rate higher than 95 percent and favorably grow and develop, provides technological conditions for saving, protecting and utilizing rare species, changes the food habit of the Sinilabeo decorus tungtings from the scrape of sessile algae into the intake of commercialfeed for benefiting the growth and the development. The pit has favorable water quality, freely intakes and distains water, is convenient to observe and can adjust the food intake of the Sinilabeo decorus tungtings at any time. In a fish disease sensitive period, fish diseases can be controlled by environment improvement and drug prevention so as to solve the problem that the wild Sinilabeo decorus tungtings are still not cultured in batches in the technical field of aquiculture and realize the mass industrialization development of the Sinilabeo decorus tungtings.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for domesticating fish, in particular to a method for inducing domestication of wild dace, a rare freshwater fish. Background technique [0002] There is a kind of fish in our country, named Xianghua dace, which belongs to the genus of cyprinidae. Mainly distributed in Dongting Lake in Hunan Province and the four rivers of Xiang, Zi, Yuan and Li. According to the statistics of more than 30 counties and cities in the region where this fish is produced, the annual output reached 219 tons at the peak. Later, due to various reasons such as damming, environmental pollution, excessive fishing and ecological changes, the resources declined seriously. By 2007, the statistics actually dropped to 423kg, less than half a ton. There are only 5 natural spawning grounds for this wild fish species that are on the verge of extinction, and they are distributed in a few counties such ...
