Transferring and classified temporary culturing system suitable for fish concentrated transportation in dam

Abstract

The invention provides a transferring and classified temporary culturing system suitable for fish concentrated transportation in a dam. The system comprises a chute, a temporary culturing pond and a grading grating, wherein the chute is an obliquely arranged transportation channel and is provided with a counting device; a fish inlet is formed in one side of the temporary culturing pond and connected with an outlet of the chute, the temporary culturing pond is divided into two temporary culturing areas through a baffle, and the temporary culturing pond is provided with an electric valve, a submersible pump and an oxygenation device; and the grading grating is installed in the temporary culturing pond and is provided with grating strips with the front ends inclining downwards, the ends, close to the chute, of the grating strips are installed on the bottom face of the fish inlet, the other ends of the grating strips are scattered and fixed to the baffle in a fan shape, fishes flowing out of the chute are conveyed into the temporary culturing pond through the grading grating, small fishes with small sizes fall into the first temporary culturing area from gaps among the grating strips, and big fishes slide to the second temporary culturing area from the grading grating. According to the system, the fishes can be well counted, classified and temporarily cultured, and the survival rate of the fishes can be effectively ensured.

Description

technical field [0001] The invention relates to the field of system design for collecting and transporting fish, in particular to a system for transferring and classifying and temporarily raising fish for collecting and transporting fish in dams. Background technique [0002] The construction of water conservancy and hydropower projects inevitably destroys the connectivity of rivers, blocks the migration channels and gene exchange of fish, and causes the destruction of fish living environment and ecological diversity. Therefore, the design and construction of fish passage facilities for the purpose of fish resource protection, such as fishways, fish collection and transportation systems, fish gates, or fish passage facilities in different combinations, has received extensive attention. [0003] Among them, the fish collection and transportation system refers to the artificial auxiliary system that transports fish across the dam by car or fishing boat through methods such as ...

AI Technical Summary

Problems solved by technology

A complete process often needs to transfer the lured fish many times to the temporary storage pond for temporary storage, and then transport them to the destination after accumulating a certain amount. This method greatly increases the transportation cost and wastes a lot of manpower and material resources.
