Example Embodiment

[0015] Example 1,

[0016] (1) Build a rectangular brick-concrete domestication pool with a cement-masonry surface. The surface of the domestication pool is smooth. The pool is 80 cm deep, 150 cm wide, and 300 cm long. The bottom surface of the pool cavity of the domestication pool is covered with commercially available ordinary white tiles or commercially available ordinary beige tiles, and both ends of the pool are respectively provided with a water inlet with a filter and a drain with a filter. Uninterrupted delivery of water to the acclimation pool through the water inlet, continuous drainage to the outside of the acclimation pool through the outlet, keeping the pool water in a micro-flow state, the daily pool water exchange volume is 80-100% of the water storage in the pool, dissolved in water Oxygen is above 5 mg / L;

[0017] (2) In late May, select 1,000 juveniles of Xianghua mud carp with a body length of 1.5 to 2.0 cm, put them in 20 liters of 2 to 3% salt water for 5 minu...

[0025] (1) Construct a rectangular brick-concrete domestication pool with a cement-masonry surface. The surface of the domestication pool is smooth. The pool is 100 cm deep, 300 cm wide, and 600 cm long. The bottom surface of the pool cavity of the domestication pool is covered with commercially available ordinary white tiles or commercially available ordinary beige tiles, and both ends of the pool are respectively provided with a water inlet with a filter and a drain with a filter. Uninterrupted water delivery to the acclimation pool through the water inlet, and continuous drainage to the outside of the acclimation pool through the drain outlet to keep the pool water in a micro-flow state. The daily pool water exchange volume is 80-100% of the water storage in the pool, dissolved in water Oxygen is above 5 mg / L;

Abstract

The invention relates to a method for artificially domesticating sinilabeo decorus tungting juvenile fishes. The method comprises the following steps: (1) establishing a domesticating pond with a brick-concrete structure, and maintaining water in the pond in a micro-flow state; (2) selecting the sinilabeo decorus tungting juvenile fishes with the lengths of 1.5-2.0 centimeters; (3) after three days, (3.1) continuously spreading mash feed on the water surface of a water inlet end for 18-20 days; (3.2) conveniently increasing the adding mount of the feed for the juvenile fishes every two days for 8-10 days; (3.3) continuously feeding the fishes by using sieve plates capable of sinking in water for 12-15 days; and (3.4) feeding extruded feed capable of floating on the water surface, covering the feed with the sieve plates and then feeding for 3-4 days; and (4) arranging frames capable of floating, spreading the feed and feeding for 3-5 days, and enabling the juvenile fishes to swing onto the water surface to eat the feed in the frames. By the method, large-scale breeding and industrial development of upstream riptide fishes with scraping feeding habit become possible, and the implementing effect is good.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for artificially domesticating juvenile Xianghua dace. Background technique [0002] Xianghua dace, belonging to Cyprinidae, is a large economic fish endemic to Hunan Province, China. Xianghua dace has tender meat, rich nutrition and excellent taste. Before the 1980s, it was distributed in Dongting Lake and the four rivers of Hunan, Zi, Yuan and Li. The highest annual output in history once reached 219 tons. Later, due to various reasons such as river damming, environmental pollution, overfishing and ecological changes, the fish resources have declined seriously, and the natural production has dropped to less than 0.5 tons in recent years. The scarcity of resources has caused the market price to soar, and the current price of Xianghua dace has reached 250-300 yuan / kg. In order to rescue and develop this rare fish, Xianghua mud carp, researchers from the Hunan Provinc...
