[0043] The auxiliary assembly 3 includes a floating plate 301, a positioning cylinder 302, a limiting threaded cylinder 303, a limiting screw 304, an operating slot 305, a clamping ring 306, a handle 307, a polyethylene bag 308, a counterweight 309, a mounting slot 310, a feed box 311, a sealing cover 312, a handle 313, and a sliding slot 314;

[0044] The outer side of the extension rod 208 is slidably sleeved with a positioning cylinder 302, the outer side of the positioning cylinder 302 is welded with a limiting threaded cylinder 303, the inner side of the limiting threaded cylinder 303 is threadedly connected to the limiting screw 304, the inner side of the floating plate 301 is provided with an operating groove 305, the inner side of the floating plate 301 is slidably clamped with a clamping ring 306, the inner side of the floating plate 301 is provided with an embedding groove at the corresponding position of the clamping ring 306, the clamping ring 306 is clamped on the inner side of the floating plate 301 through the embedding groove, which is conducive to fixing the clamping ring 306, and a handle 307 is welded on the top of the clamping ring 306. A polyethylene bag 308 is bonded to the bottom end of 306, and a counterweight block 309 is bonded to the bottom end of the polyethylene bag 308. A mounting groove 310 is provided on the inner side of the floating plate 301, and a feed box 311 is embedded in the inner side of the mounting groove 310. A sealing cover 312 is clamped on the top of the feed box 311, and a handle 313 is welded to the top of the sealing cover 312. A sliding groove 314 is provided on the inner side of the positioning cylinder 302, and the inner diameter of the sliding groove 314 is equal to the outer diameter of the extension rod 208. The contact surfaces of the sliding groove 314 and the extension rod 208 are both smooth curved surfaces, which are convenient for installing and removing the floating plate 301.

[0045] The working principle and use process of the present invention are as follows: First, the operator determines the overall water depth of the spawning area, and then determines the number of extension rods 208 to be used according to the water depth. Then, the threaded rod 209 at the top of the primary length rod 211 is tightened to the inner side of the threaded connection groove 210, thereby connecting the extension rod 208 and the primary length rod 211. After all the extension rods 208 are connected, the operator inserts the primary length rod 211 into the water. At this time, the stabilizing needle 213 at the bottom of the stabilizing plate 212 can be inserted into the bottom mud of the water area, so that several extension rods 208 can be connected. The extension rod 208 is fixed, and then the sliding sleeve 207 is put on the outside of the extension rod 208. At this time, the interior of the pressurized tank 215 is full of air, so the fixed grid 1 will float on the water surface. Then the operator can remove the top grid 202, and the magnetic attraction between the top grid 202 and the magnet 204 can be released. Then the operator can place the fish that need to spawn inside the fixed grid 1, and then re-attract the top grid 202 on the top of the magnet 204 to fix it. Then, some species of fish need deeper temperature. When spawning in lower waters, the operator can control the external air pump to pump air and open the solenoid valve 220. At this time, the external air pump will pump air through the air hose 219. At this time, the air pressure inside the pressurized tank 215 becomes smaller, and then the water will pass through the filter 217 and the inlet and outlet pipes 216 into the pressurized tank 215. After a certain amount of water enters, the pressurized tank 215 will sink, and at this time, the fixed grid 1 and the fish inside will all sink, thereby lowering the fixed grid 1 to the corresponding water depth. At this time, the water depth can be judged according to the release length of the air hose 219, and the pressure can be controlled by the operator. The amount of water in the pressurized tank 215 can control the fixed grid 1 to different water depths, so that different spawning fish can spawn in water temperatures suitable for them. After the fish spawn, the fixed grid 1 can be floated up according to the needs of the seedlings, thereby increasing the temperature in the seedling growth area and helping the seedlings survive better. When the fixed grid 1 is raised or lowered, it is raised or lowered vertically in the same water area. Because it is fixed in position by the extension rod 208 and the primary length rod 211, it will not change position due to water flow, thereby preventing environmental changes during the spawning period from reducing the survival rate.

[0046] Then, before releasing the fish, the fish can be placed on the inner side of the polyethylene bag 308, and then the operator can hold the handle 307 to clamp the clamping ring 306 and the polyethylene bag 308 on the inner side of the float 301, so that the fish can adapt to the water environment in advance. Then, during this application process, the operator can stand on the top of the float 301 to perform other operations, and can put the positioning cylinder 302 on the outside of the extension rod 208 and then tighten all the limiting screws 304 on the inner side of the limiting threaded cylinder 303 to fix the float 301 to prevent shaking, so that the operator can perform the midwifery operation more safely. Before releasing the fish, the operator can place the fish feed on the inner side of the feed box 311 and then clamp the feed box 311 to the inside of the mounting groove 310. In the subsequent spawning process, the sealing cover 312 can be directly opened to feed through the operating groove 305. The operation is simple and convenient to improve the midwifery efficiency.
