Description
STEREOSCOPIC ARTIFICIAL FISH NEST FOR PROMOTING NATURAL PROPAGATION
OF FISH THAT LAY VISCID EGGS IN RESERVOIR REGION
The present invention relates to the technical field of artificial fish nests, and in particular to a stereoscopic artificial fish nest for promoting natural propagation of fish that lay viscid eggs in a reservoir region.
Fish are an important part of a river ecosystem, as well as an important part of aquatic biological resources and biodiversity. Affected by the development of river water conservancy and the construction of barrages, some links of fish propagation are cut off, which will affect or destroy the fish propagation, and result in a decline in fish resources. There are many types of river fish that lay viscid eggs, and their fertilized eggs need to adhere to substrates such as rocks, silts, aquatic plants or mussels to complete the embryonic development process. With scheduling of a water storage operation of a large-scale reservoir, a river habitat changes, making spawning environments required for many fish that lay viscid eggs disappear. For example, eggs laid on an aquatic plant substrate in a shallow coastal water by fish that lay eggs adhering to plants are exposed to air to dry up and die. These fish lost their natural breeding conditions, leading to a sharp decline in the number and species of fish.
At present, a general method to protect and restore fishery resources of fish that lay viscid eggs is to set up artificial fish nests in rivers and lakes to provide spawning environments for the fish that lay viscid eggs, so as to expand the spawning scale and increase their resources.
However, the previous artificial fish nests are of simple structures, are only effective for fish that lay eggs adhering to plants and use aquatic plants as an adhesion substrate, and are not suitable for fish that use rocks, silt, shells, and the like as adhesion substrates. In particular, fish using different spawning adhesion substrates have different water depth preferences. Some fish-nest ecological revetments take into account fish using different spawning adhesion substrates to a certain extent, but they are only effective for reservoirs with fairly constant water levels. For a reservoir with a great water level fluctuation, when a water level drops too fast or the water level is lower than a revetment, functions of the fish-nest ecological revetments will be unavailable, and moreover, the fish-nest ecological revetments are expensive and difficult to operate.
Therefore, there is an urgent need for an artificial fish nest for fish that lay viscid eggs and that have different preferences for spawning substrates so as to alleviate the impact of a water storage operation of a reservoir on these resources of fish that lay viscid eggs. The stereoscopic artificial fish nest for promoting natural propagation of fish that lay viscid eggs in a reservoir region of the present invention can effectively fill in the above-mentioned technical gap, can be used in specific production practices, and is of great significance to protect these resources of fish that lay viscid eggs, maintain local fishery resources, and protect the watershed biodiversity.
