Description
Technical Field
The invention relates to an environment-friendly composite artificial fish nest, and belongs to the technical field of artificial fish nests.
Background
With the rapid increase of population, the demand of aquatic products is continuously increasing. However, due to the influence of a plurality of natural factors and human factors, such as climate warming, land source deposition rate acceleration, water conservancy step development, cross-basin water transfer, over fishing, leisure and entertainment, aquatic organism resources are seriously attenuated, the ecological environment of a water area is continuously deteriorated, and spawning sites and habitats of fishes are seriously damaged.
The water conservancy project construction of rivers and lakes has great influence on the ecological environment of a water area, and plankton is seriously damaged due to the rise of the concentration of suspended matters in the water body during the construction; the living environment of the benthonic animals is destroyed, so that the species and the quantity of the benthonic animals are reduced, and the oviposition substrates of the benthonic animals are changed; causing the hardening of the beaches, influencing the growth of aquatic plants and indirectly influencing the breeding and development of fishes producing viscous eggs or sinking eggs. The construction of the dam also seriously blocks the upstream and downstream migration channel of the fishes, so that the fishes cannot complete the normal life cycle and are endangered to be extinct. The main reasons for the decline of fishery resources such as white lake are caused by over-fishing, aggravation of pollution, sediment accumulation and the like. Now incorporated into the global three environmental problems of biological invasion, climate change and habitat loss, which severely affect fishery resource proliferation. The management and restoration of fishery environment and resources are urgent in view of the problems of reduction of economic fishes, fishing scale, resource miniaturization and the like. And the artificial fish nest is put into the fish pond, which is one of the most effective modes for fishery resource proliferation and habitat restoration at present.
The traditional artificial fish nest module mainly adopts plastic bottles, plastic woven bags, PVC plastic pipes, old tires, artificial plants and the like as matrix materials, has poor water permeability and is not beneficial to the survival of aquatic animals, plants and microorganisms. Moreover, the artificial fish nest has low attraction, poor adhesion effect, complex management process, low variability, high instability and inconvenient operation, and can cause a great deal of pollution due to improper recovery.
In conclusion, the water permeability of the artificial fish nest is poor at present, so that the artificial fish nest is not beneficial to the survival of aquatic animals, plants and microorganisms such as fish; the traditional artificial fish nest only provides a fish spawning place, and cannot provide artificial fish nest functions of hatching, egg attachment, food, avoidance of enemies, shore fixation and perching.
