A kind of fishery environmental protection device used for separate breeding of various fishes

Abstract

The invention discloses a fishery environmental protection device for separate cultivation of various fishes, which comprises separate cultivation ponds, water storage plates and bottom ponds arranged in the river channel, and water inlets are arranged on each of the plurality of separation cultivation ponds. A block is fixedly connected between the inner side wall of the separate culture pool away from the end of the bottom tank, and a water flow acceleration device is arranged in the water inlet. The present invention can control the speed of the water flow in each separate culture tank by rotating the knob, which has met the needs of the life habits of different kinds of fish for the speed of the water flow when they are separately cultured, and can carry out separate separation of various fishes in the same river at the same time. and maintain the liquid level at the water inlet lower than the height of the top of the water inlet with the help of the liquid level compensation device, so that when the river is stirred to accelerate the river water during rotation, air can be mixed into the river water, thereby achieving aeration and increasing separate nutrition The oxygen content in the inland river water is more conducive to the growth of fish.

Description

Technical field [0001] The present invention relates to the field of fishery environmental protection technology, in particular to a fishery environmental protection device for the feeding of a variety of fish. Background [0002] All marine and inland waters suitable for the survival, reproduction and growth of economic aquatic organisms belong to the fishery environment, and the protection of the fishery environment is not only reflected in the control and control of environmental pollution of water bodies, but also includes the protection of fish species and the avoidance of fishery biological invasion. [0003] The existing fishery environmental protection devices are used for fishery breeding in inland rivers, there is a problem of single breeding of fish species and low economic benefits, and at the same time, due to the different demands of different fish species for the speed of water flow, the types of fish raised are also very restricted.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the existing fishery environmental protection device is used for fish farming in inland rivers, there is a problem of single species of cultured fish and low economic benefits. At the same time, Because the living habits of different fish species have different requirements for the speed of water flow, the types of fish to be raised are also very limited
