Abstract

The invention discloses a vertical distribution monitoring device and method for marine fish roe, aiming to provide a method for monitoring the vertical distribution of marine fish roe and effectively improving the effective monitoring area for floating fish roe in the water Vertical distribution monitoring device and monitoring method. The vertical distribution monitoring device of marine fish eggs includes a floating frame floating on the sea surface, a counterweight that sinks to the bottom of the sea, a suspension frame suspended in sea water, an upper end opening on the suspension frame, a fixed vertical pipeline with a closed lower end, Slidingly set the dynamic vertical pipeline with openings at the upper and lower ends in the fixed vertical pipeline, the upper connecting rope connecting the floating frame and the upper end of the dynamic vertical pipeline, the horizontal bar located under the fixed vertical pipeline, and the connecting horizontal bar and the suspension frame The vertical connecting rod, the lower connecting rope connecting the horizontal bar and the counterweight, the extension spring located in the fixed vertical pipeline, the monitors arranged on the inner bottom surface of the fixed vertical pipeline, and several vertical monitors located outside the fixed vertical pipeline Straight suction tube.

Description

technical field [0001] The invention relates to the field of marine monitoring, in particular to a vertical distribution monitoring device for marine fish eggs. 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 fish spa...
