Abstract

The invention discloses an open-environment fish behavior research system with the function of collecting, detecting, catching and stocking. The floating plate above the glass conduit and the sinking body connected below the glass conduit, the glass conduit is vertically arranged, a cart is arranged inside the glass conduit, a set of guide wheels are arranged on both sides of the cart, each set of guide wheels The wheel surfaces of the wheels are all close to the inner wall of the glass conduit, and a fish finder is arranged on the cart; the inner wall of the glass conduit is provided with two sponge strips extending along the axis of the glass conduit, and each group of guide wheels corresponds to a tight Pasted on a sponge strip, the optical decoy net includes a net body and several optical fibers distributed on the net body, the several optical fibers are divided into horizontal group optical fibers and vertical group optical fibers, and several optical fibers in the horizontal group optical fibers are distributed in parallel intervals , several optical fibers in the vertical group of optical fibers are distributed in parallel and at intervals; one end of the horizontal group of optical fibers is gathered together to form a first bundle end, and the first bundle end is provided with a first light source, and one end of the vertical group of optical fibers is gathered together to form a first bundle end Two beam ends, the second beam end is provided with a second light source.

Description

technical field [0001] The invention relates to a fish behavior research system, in particular to a fish behavior research system with the function of collection, detection, catch and stocking in an open environment. Background technique [0002] With the continuous decline of global fishery resources, in order to protect the environment and maintain the sustainable development of the world's fisheries, people's research on fish behavior has been further deepened, with the purpose of developing efficient and environmentally friendly fishing gear. Fish behavior refers to The various movements of fish are the external responses of fish to changes in the external environment and internal environment, including feeding, reproduction, and breathing. The research on fish behavior generally focuses on the orientation, signaling system, and various organs of fish. Based on the characteristics of structure and function, advanced nerve function and complex action mode, various fish ar...

[0002] With the continuous decline of global fishery resources, in order to protect the environment and maintain the sustainable development of the world's fisheries, people's research on fish behavior has been further deepened, with the purpose of developing efficient and environmentally friendly fishing gear. Fish behavior refers to The various movements of fish are the external responses of fish to changes in the external environment and internal environment, including feeding, reproduction, and breathing. The research on fish behavior generally focuses on the orientation, signaling system, and various organs of fish. Based on the characteristics of structure and function, advanced nerve function and complex action mode, various fish are distributed in lakes, rivers, oceans and other environments. When catching various fish, it is necessary to use a fish finder to detect the situation of the fish , such as the distribution and behavior of fish in various hydrological environments or water depth conditions, and even the behavior of school fish and the distribution of school fish. The early research on fish behavior mainly used small individuals to replace fish species in Observation in the laboratory, the equipment and method of observation are relatively simple. With the application of computer technology, underwater photography technology, high-performance optical and acoustic equipment, the research methods of fish behavior are more diversified. To detect the behavior of fish, it can only detect the position of fish in the water, etc., because the light below the water surface is weak, and the shooting environment is not good. Even with the existing lights, it is difficult to form a large area of ​​background light. A relatively clear image is taken. Traditional fish research does not use cross-set optical fibers, so that a light source overlapping area is formed between the vertical optical fiber network and the horizontal optical fiber network, and complex light irradiation cannot be performed through the light source overlapping area. conducting fish trapping studies
