Fishery resource monitoring system for sea area restoration area

Abstract

The invention discloses a fishery resource monitoring system for a sea area repairing area. The invention aims at providing the fishery resource monitoring system for the sea area repairing area in order to effectively enlarge the effective monitoring area of floating fish eggs in water and effectively solve the problem of influences of accumulation or adhesion of sediments and the like on the shooting sharpness. The system comprises a floating frame floating on the sea, a balancing weight settling to the seabed, a suspending frame suspending in seawater, a fixed vertical pipeline arranged atthe upper opening and lower opening of the suspending frame, a mobile vertical pipeline slidably arranged at an upper opening and a lower sealing in the fixed vertical pipeline, a plurality of lateralwater feeding pipelines arranged at the lower part of the fixed vertical pipeline, an upper connecting rope for connecting the upper end of the floating frame with the mobile vertical pipeline, a tension spring positioned in the fixed vertical pipeline, a transverse rod positioned below the fixed vertical pipeline, a vertical connecting rod for connecting the transverse rod with the suspending frame, a lower connecting rope for connecting the transverse rod with the balancing weight, and a floating detector arranged on the fixed vertical pipeline.

Description

technical field [0001] The invention relates to the field of marine monitoring, in particular to a fishery resource monitoring system in a sea area restoration area. Background technique [0002] Fish spawning grounds are waters where fish and shrimp gather and breed, and are one of the most important physical environmental factors for fish. Most of the spawning grounds of fish and shrimp in the ocean are near the estuaries of large rivers along the coast. For example, the famous Jiangsu Lusi Fishing Ground in China is a spawning ground for large yellow croakers, small yellow croakers, pomfrets, and squids; Zhejiang Zhoushan Fishing Ground is a spawning ground for hairtail, Large yellow croaker, squid and other spawning grounds. [0003] The monitoring of fish spawning is one of the important means to study fish reproduction and reproduction, and it is also an important means to study fishery resources in sea restoration areas. One of the current monitoring devices for fis...
