[0021] The specific contents of the utility model are further described below. Example

[0022] The utility model is a fish measuring device for parent-child and large-size fish species, comprising a gathering cylinder 1, an external frame 2, an internal positioning net 3, a release flare 4 and a scale 5. The gathering cylinder 1 is in a flared shape, and the lower opening is connected to one end of the internal positioning net 3. The other end of the internal positioning net 3 is provided with the release flare 4. The internal positioning net 3 is fixed to the center of the external frame 2. The scale 5 is arranged on the external frame 2, and the length direction is consistent with the direction of the internal positioning net 3.

[0023] The internal positioning net 3 is connected horizontally and vertically, the longitudinal part is a deformable plastic, and the transverse part is an elastic rope, the ends of which will expand after being stretched. The release expansion 4 is a toothed ring structure, including adjacent strips 41 hingedly connected at the ends.

[0024] The gathering tube 1 is a plastic tube with a smooth inner wall, a large outer opening, a small inner opening, and a water hole 11 on the side.

[0025] The release expansion 4 is a circle formed by hinged connection of two ends of the strip 41 . After the strip 41 is stretched, the inner diameter of the release expansion 4 becomes larger.

[0026] The release flare 4 is connected to the lower part of the outer frame 2 through a plurality of arc strips 42, and a ring is provided at the end of the arc strip 42 to be sleeved on the strip 41 and the lower end of the outer frame 2. The arc strip 42 can also be replaced by an elastic rope.

[0027] By reaching into the release flare 4 with your hand, the release flare 4 is expanded, and at the same time, it slightly rotates relative to the external frame, and the arc strip 42 rotates accordingly, so that the release flare is connected to the external frame, and the distance between the release flare and the external frame can also change as the arc strip rotates with the release flare 4. Otherwise, the release flare 4 is reduced.

[0028] The front end of the internal positioning net 3 is connected to the closing end of the gathering tube 1. The fish to be measured enters the internal positioning net 3 through the gathering tube 1, and the release expansion 4 of the internal positioning net 3 is squeezed, and the opening is reduced. The external frame 2 in the device is cylindrical, including end rings 21 at both ends and longitudinal rods 22 on the side. One end of the ring is fixed to the outside of the closing end of the gathering tube 1, and the other end is fixedly connected to the arc strip 42. A plurality of longitudinal rods 22 are parallel and fixedly connected to the rings at both ends. The longitudinal rod 22 is on one side of the cylinder and fixed to the scale 5. Example

[0029] The release flare 4 in the device is changed into two arc-shaped hard strips, the ends of which are connected by elastic ropes, and elastic ropes are arranged between the strips and the external frame 2 structure for intermediate positioning.

[0030] When releasing the fish, the two strips are opened by hand, the elastic rope is stretched, and the release expansion 4 becomes larger to release the measured fish.

[0031] When in use, the caught fish is put into the gathering tube 1, and water flows out from the water hole. The inner wall of the gathering tube 1 is smooth to reduce friction and obstruction. The fish enters the internal positioning net 3 from the gathering tube 1, and the release expansion 4 at the end is squeezed and shrunk. The internal positioning net 3 is also squeezed and shrunk at the end of the gathering tube 1. The fish is positioned in the internal positioning net 3, and the scales of the fish head and tail are read, and the difference is taken to calculate the length of the fish. The device including the fish is placed on the scale, and the weight of the fish and the device is weighed. After the fish is released, the device is weighed separately to calculate the weight of the fish.

[0032] After weighing and measuring, the release flare 4 is expanded and tilted toward the water to release the fish from the internal positioning net 3.

[0033] The utility model can realize the fixed positioning of fish and the measurement of fish, and is more convenient for operators than the existing manual positioning. The fish can be positioned to a certain extent, and the measurement accuracy is higher. The mesh positioning net is used for positioning, which reduces the pinching damage to the fish.
