[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 2 The utility model provides a technical solution: a device for measuring underwater fish morphological characteristics.

[0027] It comprises a main body 1, and openings 2 are respectively provided at two ends of the main body 1;

[0028] The two openings 2 are respectively provided with gate assemblies 3 for opening or closing the measurement lane 4;

[0029] The body 1 is provided with a measuring swimming lane 4, which is cylindrical and arranged in the body 1. A feed box 5 is arranged in the measuring swimming lane 4, and both ends of the measuring swimming lane 4 are respectively connected with the two openings 2;

[0030] A camera assembly 6 is provided on one side of the measuring lane 4 for taking images of the inside of the measuring lane 4;

[0031] The telescopic bracket 8 is fixedly connected to the main body 1 and is used to place the main body 1 into water to adjust the water depth of the main body 1.

[0032] The measuring device body 1 can be placed at different water bottom depths by using the telescopic bracket 8 to perform induction measurement on different fish species;

[0033] Fish are attracted to swim into the measuring lane, and the fish are temporarily enclosed in the measuring lane 4 by a gate. The fish in the measuring lane 4 is imaged by the camera assembly 6, and information about the fish is obtained by image analysis.

[0034] The length of the measuring swimming lane 4 is 30 to 60 cm. The length of the measuring swimming lane 4 is used to adapt to various fish species, and different specifications can be adjusted according to the fish species.

[0035] The gate assembly 3 includes a driving assembly and a gate. The driving assembly is connected to the gate to control the gate opening and closing. The driving assembly is a motor or a cylinder.

[0036] The gate is opened and closed by a driving component, and the driving component can be set to be click-driven or cylinder-driven.
