Embodiment Construction

[0031] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0032] Such as Figure 1 to Figure 4 Shown, a kind of modularized artificial fish nest system of the present invention, the upper part of described fish nest system is equipped with sinker 3 and ovum sticky matrix A, and the bottom is equipped with floater 4 and ovum sticky matrix B, and described fish nest The system includes several fish nests 1 that are detachably connected together. When in use, the sinker 3 is installed on the top of the fish nest system to facilitate the increase or decrease of the sinker 3 to adjust the distance between the fish nest 1 and the water surface.

[0033] The fish nest 1 includes a lower frame 10 and an upper frame 12, and the upper frame 12 is connected to the lower frame 10 through a plurality of support plates 11 arranged side by side. When in use, the lower frame 10, the upper frame 12 and ...

Abstract

The invention discloses a modular artificial fish spawning nest system and an installation method thereof, and belongs to the technical field of aquatic resource restoration. The upper portion of thefish spawning nest system is provided with a sinker and an egg sticky matrix A, the lower portion of the fish spawning nest system is provided with a floater and an egg sticky matrix B, and the fish spawning nest system comprises a plurality of fish spawning nests connected detachably. A bundle of Myriophyllum spicatum L., a bundle of hornwort, a bundle of potamogeton cristatus, a bundle of club moss or a bundle of Schoenoplectus wallichii are bound and fixed on the top of the fish spawning nest system, so that fishes with sticky eggs can lay eggs and breed, and a habitat is provided for growth of juvenile fishes. Polyethylene fiber wire balls are bound and fixed on the bottom of the fish spawning nest system, so that fishes with sticky eggs can lay eggs and breed, and a habitat is provided for growth of juvenile fishes, and the polyethylene fiber wire balls can be repeatedly used. The egg sticky matrix A and the egg sticky matrix B are fixed on the fish spawning nests, and are not easy to float greatly, so that fish eggs can be attached to the egg sticky matrix A or the egg sticky matrix B.

Description

technical field [0001] The invention relates to a modular artificial fish nest system and an installation method thereof, belonging to the technical field of aquatic resource restoration. Background technique [0002] Due to the development of industrialization, water resources have been polluted to varying degrees, and natural water bodies such as rivers, lakes, and reservoirs have undergone varying degrees of eutrophication, and the growth of aquatic vegetation has been greatly negatively affected, resulting in changes in the ecological environment for fish activities. , the natural aquatic grass wetlands where fish breed and spawn are decreasing day by day, and the fertilization rate and survival rate of fish eggs are declining, resulting in a serious decline in natural fishery resources. Artificial fish nests are built and placed in natural waters where fish are active, so as to allow fish to multiply naturally Create a suitable environment for spawning, expand the scale...
