Embodiment Construction

[0033] The present invention will be further described below with reference to specific embodiments and accompanying drawings. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of application of the present invention.

[0034] like figure 1 As shown, the artificial fish nest of the present invention includes a floating row 1 as a floating structure, and the adhesive structure and the floating row 1 can be connected by ropes. exist figure 1 In this example, the top of the column frame 2 is provided with a connecting rod 9 , and the floating row 1 is connected with the connecting rod 9 through the top connecting rope 10 , so as to realize the connection with the column frame 2 .

[0035] It is worth noting that the "floating structure" mentioned herein refers to any structure that can float on the water surface, including but not limited to any floating row, float, etc. made of natural materials or synth...

Abstract

The invention provides an artificial fish nest. The artificial fish nest comprises a floating structure and an adhesion structure connected with the floating structure, wherein the adhesion structurecomprises a columnar frame and an adhesion matrix positioned in the columnar frame, and the columnar frame is provided with at least one opening. The artificial fish nest provided by the invention canfully utilize the space of a water body to provide a spawning place for viscous egg-producing fishes, is favorable for hatching floating fish eggs, provides a shelter place and a baiting place for juvenile fishes, and has a long service life, the space of a water surface and an underwater water column can be fully utilized, the spatial heterogeneity of a habitat environment of fishes is improved,the biodiversity is improved effectively, and the ecology of the water body is restored.

Description

technical field [0001] The invention belongs to the application field of aquatic products, and in particular relates to an artificial fish nest and use thereof, and a method for restoring water body ecology through the artificial fish nest. Background technique [0002] Human activities such as the construction of cascade power stations and reservoirs have resulted in fragmentation of river habitats, intensified lake formation, destruction of habitat diversity, loss or reduction of fish habitats, and destruction of fish spawning sites, resulting in the decline of fishery resources. On the one hand, the change of habitat reduces or lacks aquatic plants in natural water bodies, resulting in the loss of the original spawning sites for sticky spawning fish; The eggs do not have enough time to hatch. At the same time, the reduction of habitat diversity makes the larvae and juveniles lack the necessary shelter, which increases the risk of predation, reduces the number of fish pop...
