Problems solved by technology

At the end of the 20th century, the released Chinese sturgeons were mainly splash fry, which were easily preyed on by other fish, resulting in a low survival rate of artificially multiplied and released Chinese sturgeons
At present, there are no reports on the wild training of Chinese sturgeon at home and abroad. Therefore, it is urgent to find out a wild training method for Chinese sturgeon. Effective training of farmed Chinese sturgeon before release can improve the survival of released Chinese sturgeon in the wild. Ability to increase the survival rate of released Chinese sturgeon in the wild

Embodiment 1

[0022] A wild training method for Chinese sturgeon, said method comprising: feeding habit transformation, exercise for improving swimming ability and exercise for improving predation ability; after the completion of feeding habit transformation, the exercise for improving predation ability can be carried out, the exercise for improving swimming ability and feeding habit transformation or improving predation ability can be carried out Ability training can be carried out at the same time.

[0023] Preferably, the dietary conversion includes feeding artificial domestication feed and feeding biological bait;

[0024] Described feeding artificial domestication feed: After releasing the Chinese sturgeon to the wild training pool, first starvation treatment 3-4d, and then feeding artificial domestication feed; crucian carp, turbot, sea shrimp by weight 1: The method of 0.8-1.2:0.8-1.3 is chopped into meat paste, stirred with feed and dried evenly to make artificial domestication feed...

Embodiment 2

[0031] The invention discloses a method for rewilding Chinese sturgeon, the steps of which include feeding habit conversion, training for improving swimming ability and training for improving predation ability. After the conversion of feeding habits is completed, the improvement is not ability training, and the training of improving swimming ability and the training of feeding habits conversion and improving predation ability can be carried out at the same time.

[0032] The dietary conversion includes feeding artificial domestication feed and feeding biological bait;

[0033] Described feeding artificial domestication feed: after releasing the Chinese sturgeon to the wild training pool, first starvation treatment 3-4d, and then feeding artificial domestication feed; crucian carp, turbot, sea shrimp by weight 1: Chop meat into puree at a ratio of 1:1, mix it with feed and dry it evenly to make artificial domestication feed; the ratio of meat paste to feed is 1:4 at the beginning...

Abstract

The invention relates to a wild-training method for Chinese sturgeon. The method comprises the steps of converting feeding habits, improving swimming capacity and improving predation capacity. Only when feeding habit conversion is completed, can the predation capacity be improved, and the improvement of swimming capacity and predation capacity and feeding habit conversion can be conducted synchronously. By adopting the method, the feeding habit of the released Chinese sturgeon is successively converted into freshwater and seawater creature baits from artificial compound feed, and the problem of conversion of feeding bait types of the released Chinese sturgeon is solved; by feeding the released Chinese sturgeon with live baits of the moving capacity from weak to strong, the capacity of actively catching the live baits of Chinese sturgeon is greatly improved, and the wild-adaptability capacity of the released Chinese sturgeon is greatly strengthened; the swimming capacity, especially theswimming capacity in adverse water flow of the Chinese sturgeon is greatly improved in a mode of intermittently creating stair water flow, the physique of the Chinese sturgeon is greatly improved, and wild predation and anti-predation of the Chinese sturgeon are ensured greatly.

Description

technical field [0001] The invention belongs to the technical field of rare and unique fish breeding, and in particular relates to a wild training method for Chinese sturgeon. Background technique [0002] Chinese sturgeon is a migratory cartilaginous scale fish that is mainly distributed in the main stream of the Yangtze River and the southeast coast of my country. In the late 20th century, due to many factors such as overfishing, water conservancy construction, shipping, and water pollution, its wild population resources continued to decline. Although the Chinese sturgeon was listed as a national first-class aquatic protected animal in 1988, in the 19 years from 1981 to 1999, the supplementary population of Chinese sturgeon juveniles still decreased by about 90%. Therefore, the protection and research work of Chinese sturgeon without delay. Artificial breeding and release is an important way to protect the species resources of Chinese sturgeon. So far, relevant domestic i...
