Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically to an artificial fish spawning bed. Background Art

[0002] The construction of water conservancy and hydropower projects and the cascade development of rivers have changed the hydrological and hydraulic conditions of rivers, resulting in the spawning sites of native flow-loving fish becoming smaller or disappearing due to being submerged by reservoirs, which in turn leads to a decline in the population of native flow-loving fish and even extinction. At present, setting up artificial fish nests in limited flowing river sections is considered to be an effective way to increase fish breeding sites. However, most of these artificial fish nests are floating nests, which are more suitable for fish that like to lay eggs in water plants, but are not very suitable for fish that like to lay eggs in stone cracks and gravel. In view of the breeding habits of such fish, some scholars have proposed to lay gravel and pebbles and other materials in the river sections with wide riverbeds to build artificial spawning grounds. This method can increase the area and number of fish spawning sites to a certain extent. However, the construction of such artificial spawning grounds is limited by site conditions. Not only is it inconvenient to build, but also because it is impossible to salvage the spawned fish in time, some parent fish will eat the fish eggs, resulting in a certain loss of fish eggs and fry. For this reason, this scheme provides an artificial fish spawning bed. Utility Model Content

[0012] 3. Beneficial effects:

[0013] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] The utility model has a reasonable design. A prefabricated spawning bed is placed in a water body, and a support frame is driven to the bottom of the spawning bed under the action of a transmission member, and then a spawning matrix is ​​placed on the surface of the support frame, so that the spawning matrix can adhere to fish eggs in the future and provide adhesion for the fish eggs. At the same time, a person can also put plant leaves and baits above the spawning matrix, so that the interior of the support frame presents a cool area, providing a suitable spawning environment for spawning fish. After the spawning of fish is completed, the person can drive the transmission member to drive the support frame to move upward, so that the scoop net with the spawned fish and the fish eggs attached to the spawning matrix move upward synchronously. Finally, the person can classify and process the salvaged fish eggs and fish in time, so as to avoid the parent fish eating the laid fish eggs and causing the loss of fish eggs, and the dead fish eggs can also be sorted.

[0026] During use of the present scheme, in order to avoid the phenomenon that the artificial construction of fish breeding sites is limited by the site, the construction is difficult, and the parent fish cannot be salvaged in time, resulting in the loss of fish eggs, in the prior art, in this embodiment, a pre-made integrated spawning bed is placed in the water body, and the support frame 3 is driven to the bottom of the spawning bed 1 under the action of the transmission member 4, and then the spawning matrix 5 is placed on the surface of the support frame 3, so that the spawning matrix 5 can adhere to the fish eggs in the future and provide adhesion for the fish eggs. At the same time, the personnel can also put plant leaves and bait on the spawning matrix 5, so that the interior of the support frame 3 presents a cool area, providing a suitable spawning environment for the spawning fish. Then, after the spawning of the fish is completed, the personnel can drive the transmission member 4 to prompt the support frame 3 to move upward, so that the scoop net 6 carries the spawned fish and the fish eggs attached to the spawning matrix 5 and moves upward synchronously. Finally, the personnel can classify and process the salvaged fish eggs and fish in time to avoid the parent fish eating the spawned fish eggs and causing the loss of fish eggs, and can also pick the dead fish eggs.

[0027] See also Figure 1-2 The support frame 3 includes a support frame 1 31 disposed between the inner walls of the vertical plate 2, a support frame 2 32 is disposed at the upper end of the support frame 1 31, and a plurality of connecting rods 33 are fixedly connected between the support frame 1 31 and the support frame 2 32.
