[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: A device for fish resource monitoring, comprising: a support frame, a camera platform and a bait rack, the camera platform is fixedly connected to the support frame, and the bait rack is fixedly connected to the camera platform.

[0023] The support frame includes: bolt 1-1, support 1-2 and connecting plate 1-3. There are two supports 1-2, which are detachably and fixedly connected by bolt 1-1 between the two supports 1-2. Each support 1-2 is fixedly provided with a connecting plate 1-3. The two supports 1-2 are both welded by three cross bars and two longitudinal bars, and the connecting plate 1-3 is fixed between the two longitudinal bars.

[0024] The camera platform includes: camera fixing plate 2-1, fastening plate 2-2 and bait fixing frame 2-3. Fastening plates 2-2 are fixedly provided on both sides of the camera fixing plate 2-1. The two fastening plates 2-2 are respectively detachably and fixedly connected with the two connecting plates 1-3 by screws. A bait fixing frame 2-3 is provided at the lower end of the camera fixing plate 2-1.

[0025] The bait frame includes: support 2 3-1, fixing device 3-2 and extension rod 3-3. One end of the extension rod 3-3 slides through the bait fixing frame 2-3 and is provided with a setscrew.
