Description

Three-dimensional artificial fish nest for promoting natural proliferation of fishes producing sticky eggs in reservoir area

Technical Field

The invention relates to the technical field of artificial fish nests, in particular to a three-dimensional artificial fish nest for promoting natural proliferation of fishes producing sticky eggs in a reservoir area.

Background

Fishes are an important component in a river ecosystem and are also an important component of aquatic organism resources and biodiversity. Under the influence of river water conservancy development and barrage construction, certain links of fish reproduction are cut off, and fish reproduction is influenced or destroyed, so that the fish resource amount is reduced. River fishes produce a large number of sticky eggs, and fertilized eggs of the river fishes need to be adhered to substrates such as stone, muddy sand, aquatic weeds or mussels to complete the embryo development process. The large reservoir is scheduled to store water for operation, the river habitat is changed, spawning environments required by the propagation of a plurality of sticky and sinking fishes disappear, for example, the spawning of the sticky and sinking fishes spawning on aquatic plant substrates in coastal shallow water areas die due to the fact that the fishes are exposed in the air to be dried, the fishes lose natural propagation conditions, and the quantity and the types of the fishes are rapidly reduced.

At present, a general method for protecting and recovering fishery resources producing sticky and heavy fishes is to arrange artificial fish nests in rivers and lakes to provide spawning environments for the sticky fishes, so that spawning scale is enlarged, and resource quantity is increased. However, the prior artificial fish nest has a simple structure, is only effective for grass-sticking fishes using aquatic weeds as adhesion substrates, and is not suitable for fishes using stone, silt, shells and the like as spawning substrates, particularly for fishes with different spawning adhesion substrates with different preference in water depth. Some fish nest type ecological revetments consider fishes with different spawning adhesion substrates to a certain extent, but are only effective for reservoirs with quite constant water level, and for reservoirs with large water level amplitude, when the water level drops too fast or the water level is lower than the revetments, the effect of the fish nest type ecological revetments is lost, and the fish nest type ecological revetments are high in manufacturing cost and difficult to operate.

Therefore, an artificial fish nest for producing the sticky and heavy spawning fish, which can meet the requirements of different spawning matrixes, is urgently needed to relieve the influence of reservoir water storage operation on the sticky and heavy spawning fish resources. The three-dimensional artificial fish nest for promoting natural proliferation of the fishes producing the sticky and heavy eggs in the reservoir area can effectively solve the technical blank, is used for specific production practices, and has important significance for protecting the fish resources producing the sticky and heavy eggs, maintaining local fishery resources and protecting the biological diversity of watersheds.
