Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for domesticating wild albacores imitating natural habitat rivers and the cruising pool used, which can effectively solve the problem that albacores, a fish adapted to flowing water habitats, is difficult to survive under artificial domestication conditions , from the aspects of hydrology, water quality, bottom quality and light control, simulated its natural habitat in the wild in an all-round way, established a domestication model that meets the growth and development needs of wild albacore, and laid a technical foundation for artificial breeding population reserves

Embodiment 1

[0042] A kind of domestication method of wild albacore simulant natural habitat river course, the method comprises the following steps:

[0043] 1) Constructing imitation natural habitat rivers: use long oval cruising pools as imitation river domestication pools, pile pebbles on the bottom of the pools, build artificial fish reefs 2, plant large green algae (such as Cladophora) on the inner wall and bottom of the cruising pools, and long ellipse The continuous flow-making device 3 and the instantaneous flow-making device 6 are installed in the shaped cruising pool to simulate the natural habitat of fish from the hydrological point of view, and a light and temperature control system is installed above the cruising pool to control the light and temperature of the imitation river domestication pool;

[0044] 2) Water quality control in the preparatory stage: apply liquid organic fertilizers to cultivate planktonic microalgae and zooplankton in the imitation river domestication pon...

Embodiment 2

[0064] A kind of domestication method of wild albacore simulant natural habitat river course, the method comprises the following steps:

[0065] 1) Constructing imitation natural habitat rivers: use long oval cruising pools as imitation river domestication pools, pile pebbles on the bottom of the pools, build artificial fish reefs 2, plant large green algae (such as Cladophora) on the inner wall and bottom of the cruising pools, and long ellipse The continuous flow-making device 3 and the instantaneous flow-making device 6 are installed in the shaped cruising pool to simulate the natural habitat of fish from the hydrological point of view, and a light and temperature control system is installed above the cruising pool to control the light and temperature of the imitation river domestication pool;

[0066] 2) Water quality control in the preparatory stage: apply liquid organic fertilizers to cultivate planktonic microalgae and zooplankton in the imitation river domestication pon...

Embodiment 3

[0089] Such as figure 1 As shown, a cruising pond used for domestication of a wild albacore imitating the natural habitat river course, including the pond body,

[0090] The pool body 1 is an elliptical pool body, and a water retaining wall 4 is arranged in the pool body 1 to form an annular water channel 8 in the area of ​​the pool body 1. A plurality of artificial fish reefs 2 are piled up at the bottom of the pool body 1 near the outlets at both ends. The inner wall of the body 1 and the bottom of the pool are attached with a layer of large green algae (such as Cladophora). The middle of the pool body 1 on both sides of the water retaining wall 4 is respectively equipped with an instantaneous flow device 6, and the area near the two ends of the pool body 1 is respectively equipped with continuous flow devices. The flow-making device 3 is provided with drain outlets at both ends of the pool, and the drain outlets communicate with the sewage well 7 outside the pool through th...

Abstract

The invention provides an imitated natural habitat river type domesticating method for wild rhinogobio ventralis. The method comprises the steps of 1) building an imitated natural habitat river; 2) preparing for staged water quality control; 3) performing polyculture and matching for fishes; 4) feeding wild rhinogobio ventralis to be domesticated to an imitated river domesticating pool; 5) regulating and controlling the water quality in the early stage of domesticating; 6) feeding bait in the early stage of domesticating, namely, feeding living food to the imitated river domesticating pool at the early stage of domesticating of wild rhinogobio ventralis; 7) regulating and controlling the water quality in the middle and later stage of domesticating; 8) feeding bait in the middle and later stage of domesticating, so as to finish the domesticating of wild rhinogobio ventralis in the imitated natural habitat river. With the adoption of the imitated natural habitat river type domesticating method for wild rhinogobio ventralis and a cruise pool, the problem that the fishes like wild rhinogobio ventralis living in running water habitat are difficult to domesticate artificially can be effectively solved, a domesticating mode meeting the growth and development demand of wild rhinogobio ventralis is created, and the technological foundation is provided for artificial breeding of population.

Description

technical field [0001] The invention relates to a method for domesticating wild fish and a device used therein, in particular to a method for domesticating wild albacores imitating a natural habitat river course and a cruising pool used. Background technique [0002] Rhinogobio ventralis Sauvage et Dabry, belonging to CyPriniforme, CyPrinidae, Gobioninae, Rhinogobio Bleeker, commonly known as ocean fish and earth mouse, its meat quality Delicate, delicious, with high nutritional value and economic value, it is a unique small benthic fish in the upper reaches of the Yangtze River. The albacore is adapted to running water habitats and feeds on running water benthic animals such as freshwater shellfish. It is a river migratory fish that lays eggs in rapids. Its entire life cycle is completed in the river, and it is highly dependent on the habitat of flowing water. However, due to overfishing, water pollution, and water conservancy construction in recent years, the resources o...
