Description

TECHNICAL FIELD

[0001] The utility model relates to wetland ecological restoration engineering technology and wetland biodiversity recovery technical field, concretely relates to a kind of freshwater artificial fish reef for quickly creating aquatic animal microhabitat. BACKGROUND

[0002] Artificial reefs are man-made structures designed to mimic underwater habitats and improve aquatic environments for fish and other marine life to inhabit, breed and forage. Typically constructed from hardy materials such as concrete, metal and plastic, artificial reefs can create habitats in areas lacking complex hard-bottom structures, thereby increasing species diversity. In addition to promoting the development of aquatic ecosystems, artificial reefs can also attract fish to form fishing grounds, making them commonly used in aquaculture settings to protect, propagate and increase fish catches. Currently, artificial reef construction is widely carried out both domestically and internationally, particularly in the restoration of nearshore marine habitats and fishing grounds, with significant results achieved.

[0003] While artificial reefs have been well-established in marine and nearshore ecosystems, their application in freshwater lakes, reservoirs and riverways remains relatively limited. This is primarily due to the design and materials used in existing artificial reefs, which are more suitable for marine environments. For example, while monolithic reefs made of concrete have certain advantages in terms of material sourcing, cost and environmental impact, their large size, solid structure and high transportation difficulty significantly increase the cost of transportation and deployment in freshwater environments.

[0004] Existing artificial reefs are mostly designed as monolithic structures, lacking flexibility and making it difficult to adapt to specific freshwater environments. Additionally, the combination of these reefs is often complex, making large-scale production and promotion challenging. In the market, most artificial reef products adopt a bottom-sitting design, primarily utilizing the space at the bottom of water bodies, while neglecting the effective use of resources in the middle and upper layers of water. More importantly, the structural design of existing reefs often fails to fully consider the size characteristics and ecological habits of dominant fish species in freshwater environments, particularly those herbivorous and filter-feeding fish that are largely distributed in the middle and upper layers of water. This results in these reefs being ineffective in defending against predators, making it difficult to meet the diverse needs of aquatic organisms in freshwater ecosystems. While floating reefs have been proposed as a potential solution, their application in ecological restoration is still in the early stages of exploration.

[0005] The existing artificial fish reefs have relatively single function, mainly as breeding sites for aquatic organisms, and they lack interaction with other ecological products and fail to form a complete micro-wetland biological habitat system, which limits the potential of artificial fish reefs in attracting aquatic organisms and improving habitat environment, and the role of artificial fish reefs in wetland ecological restoration and biodiversity restoration cannot be fully played, therefore, it is particularly important to develop a new type of artificial fish reef which can adapt to fresh water environment, quickly create micro-habitat for aquatic animals, have flexible combination mode, fully utilize water resources and promote the integrity of wetland ecosystem.
