Multipurpose fish breeding station wilding training system and application method thereof

Abstract

The invention provides a multipurpose fish breeding station wilding training system. The multipurpose fish breeding station wilding training system comprises that an ecological channel is provided with a high-level reservoir, a storage pond, an ecological pond and a sewage treatment system, wherein the high-level reservoir is connected with the sewage treatment system through a water lifting pipe,and the high-level reservoir, the storage pond, the ecological pond and the sewage treatment system form a circulating channel; in the length direction of the ecological channel, every 5-10 meters isprovided with a plunge pool; one end of the water lifting pipe is provided with a lifting pump which is arranged inside the sewage treatment system; the high-level reservoir is provided with a discharging valve; the circulating channel is arranged along a fish breeding station, which is connected with the storage pond through pipes. The multipurpose fish breeding station wilding training system can make good use of existing facilities of the fish breeding station and simulate a natural water environment to improve the utilization rate of existing facilities of the fish breeding station in China and improve the field adaptability of field-bred fishes, thereby being applicable to application and generalization.

Description

technical field [0001] The invention relates to a multipurpose fish breeding station rewilding training system and a use method thereof, belonging to the field of rewilding training of released fish species in fish breeding stations. Background technique [0002] Fish multiplication and release is an important means to slow down the adverse impact of water conservancy and hydropower projects on fish, maintain the continuation of rare and endangered fish populations, and supplement economic fish resources. The work of fish multiplication and release in my country began in the late 1950s. After the 1980s, the multiplication and release activities gradually became large-scale. After 2000, the multiplication and release work developed rapidly. However, the artificial multiplication and release of fish did not achieve the expected multiplication and protection effect. One of the main reasons is that the release seedlings have poor field adaptability. , resulting in a higher mortali...

AI Technical Summary

Problems solved by technology

Restricted by the site and drainage facilities, most fish breeding and releasing stations do not have rewilding training pools, and only put them into large water bodies, reservoir bays or banks of slow-flowing rivers for over-cultivation before releasing. This method is time-consuming and laborious, and due to It is far away from the field area of ​​the multiplication and release station, and the transitional cultivation of the release seedlings is not easy to implement management. For example, the Chinese patent No. CN205390014U discloses a kind of ecological wildization temporary cultivation device for fish multiplication and release station. The distance between the wild training site of this patent The river is relatively close, and it is relatively far away from the fish breeding and releasing station, which will cause inconvenience in the operation and supervision of wild training; some fish breeding stations have set up wild training pools, but they are often circular or oval closed still water pools , the degree of wild training in this way is limited, and it is difficult to improve the wild survival adaptability of released fish species. For example, the Chinese patent No. CN103329829B discloses a wild training method for improving the anti-predation ability of released juvenile fish. This patent mainly focuses on releasing juvenile fish. The anti-predation ability of fish has been compromised, and the ecology of the training place has not been considered. Another example is the wild training method for improving the feeding ability of released Dabry's sturgeon disclosed by the Chinese patent No. CN103329830B. This patent mainly focuses on the feeding ability training of Dabry's sturgeon , did not consider the ecology of the training site, nor did it consider the swimming ability training of released fish species
