Fish behavior research system integrating detecting, catching and stocking functions in open environment

Abstract

The invention discloses a fish behavior research system integrating detecting, catching and stocking functions in an open environment. The system comprises a suspension fish detecting device and a light inducing net which are oppositely arranged in a water area; the suspension fish detecting device comprises a sealed glass guide pipe, a floating plate connected to the upper portion of the glass guide pipe and a pendant body connected to the lower portion of the glass guide pipe; the glass guide pipe is vertically arranged; a wheeler is arranged in the glass guide pipe; two sides of the wheelerare each provided with a group of guide wheels; the wheel surfaces of each group of guide wheels are tightly attached to the inner wall of the glass guide pipe; a fish detector is arranged on the wheeler; two sponge strips extending along the axis of the glass guide pipe are arranged on the inner wall of the glass guide pipe; each group of guide wheels is correspondingly clung to one sponge strip; the light inducing net comprises a net body and a plurality of optical fibers distributed on the net body; the plurality of optical fibers are divided into a transverse group of optical fibers and avertical group of optical fibers; the plurality of optical fibers in the transverse group of optical fibers are distributed in parallel at intervals; and the plurality of optical fibers in the vertical group of optical fibers are distributed in parallel at intervals; one ends of the transverse group of optical fibers are gathered together to form a first beam end, and the first beam end is provided with a first light source; and one ends of the vertical group of optical fibers are gathered together to form a second beam end, and 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
