Embodiment 1

[0012] (1) Choose a place to build a pool. Choose the water near the lower reaches of the reservoir to build cement pools as domestication pools. The domestication pool has a brick-concrete structure and is rectangular. Pool depth 1.4m, water surface area 12×3m 2 . Asbestos tiles are used on both sides of the pool wall to build a shade for the fish in the pool to shelter. The bottom surface of the pool is inclined from the water inlet end to the discharge 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 flow pool, which maintains a micro-flow state with a flow velocity 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 excellent water quality;

Embodiment 2

[0018] (1) Choose a place to build a pool. Choose the water near the downstream of the dam to build a cement pool as the domestication pool. The acclimatization pool has a brick-concrete structure and is oval in shape. Pool depth 1.5m, water surface area 60m 2 . The pool walls on both sides are respectively built with 10 prefabricated panels with an area of ​​2m 2 A cave-like shade shelter for pond fish sheltered habitat. The bottom surface of the pool is inclined from the water inlet end to the discharge end to form a uniform slope, so that the water intake and drainage are smooth, and then the water from the dam is introduced into the pool to form a flow pool, which maintains a micro-flow state, with a flow rate of 0.2m / s and a transparency of 80cm. The oxygen content is 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 commercial feed 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 and domesticating the rare freshwater fish wild rohu. Background technique [0002] There is a kind of fish in our country, named Xianghua dace, which belongs to the family Cyprinidae. It is mainly distributed in Dongting Lake and the four rivers of Hunan, Zi, Yuan and Li in Hunan Province. According to the statistics of more than 30 counties and cities in the area where this fish is produced, the annual output reached 219 tons at its peak. Later, due to various reasons such as damming of rivers, environmental pollution, excessive fishing and ecological changes, the resources declined severely. By 2007, the statistics had dropped to 423kg, less than half a ton. There are only five natural spawning grounds for this endangered wild fish species, and they are distributed in a few counties such as Hongjiang, ...
