Fishery environment protection device for separate culture of various fishes

Abstract

The invention discloses a fishery environment protection device for separate culture of various fishes. The fishery environment protection device comprises separate culture ponds, a water storage plate and a bottom pond which are arranged in a riverway, water inlets are formed in the multiple separate culture ponds, blocking nets are fixedly connected between the inner side walls of the ends, awayfrom the bottom pond, of the separate culture ponds, and water flow acceleration devices are arranged in the water inlets. By means of the fishery environment protection device, the water flow velocity in each separate culture pond can be controlled by rotating a knob, so that the requirements of living habits of the different fishes for the water flow velocity during separate culture are met, and the various fishes can be separately cultured in a same river at the same time; and the liquid levels at the water inlets are kept lower than the top ends of the water inlets by means of liquid level compensation devices, so that air can be mixed into river water when the river water is accelerated by stirring the river water during rotation, aeration is realized, the content of oxygen in the river water in the separated culture ponds of the fishery environment protection device for separated culture of the various fishes is increased, and the growth of the fishes is facilitated.

Description

technical field [0001] The invention relates to the technical field of fishery environment protection, in particular to a fishery environment protection device for separate cultivation of various fishes. Background technique [0002] All oceans and inland waters that are suitable for the survival, reproduction and growth of economic aquatic organisms belong to the fishery environment. The protection of the fishery environment is not only reflected in the control and treatment of water environmental pollution, but also includes the protection of fish species. , and to avoid biological invasions in fisheries. [0003] When the existing fishery environmental protection devices are used for fish farming in inland rivers, there are problems of single fish species and low economic benefits. The types of fish are also very limited. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the existing fi...

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
