Background
Artificial reef (Artificial reef) is one or more natural or Artificial structures which are artificially placed on the seabed, improves the ecological environment of the sea area by changing the physical, biological and social economic processes related to marine organism resources, creates a good environment for the inhabitation of marine organisms, provides places for the reproduction, growth, bait-seeking and enemy avoidance of fishes and the like, achieves the purposes of protecting, proliferating and improving the fish harvest yield, and has become a fishery management tool which is generally adopted by countries on the coastal world. The artificial fish reef is an artificial habitat which is formed by one-time interference on an ecological system, and as the material of a reef body is different from the seabed substrate, and factors such as the surrounding flow state, the water depth and the like are greatly different from the natural reef, the artificial reef inevitably causes the process of 'environmental change-competitive relationship change-community structure change' theoretically, and finally forms a unique biological community different from the natural habitat. Since the fourth international artificial fish reef conference in 1988, the change of artificial fish reef biocenosis is receiving increasing attention of marine ecologists, and related research results also provide important references for reasonable development and utilization of artificial fish reefs. Regarding the research on the evolution of the fish community structure in the artificial fish reef area, the analysis of the fish population quantity and community structure change in the reef area before and after reef throwing (or with a natural sea area as a contrast) is a research hotspot.
Hexagrammos otakii (Hexagrammos otakii) belongs to Sebastes (Actinopterygii) Sebastes (Scorpaeniformes) fishes, is offshore cold-temperature benthic species loving reef type fish species, and is widely distributed in the yellow Bohai sea and east sea areas in China. In the artificial fish reef area of the small black mountain island, the hexagrammos otakii are all fish groups with higher abundance of species in the sea area, and play a vital role in material circulation and energy flow in the sea area in a food network. The roe of the hexagrammos otakii is a sticky egg, the ovulation distribution of the hexagrammos otakii before and after the artificial fish reef is thrown into the reef is researched, and the fish collecting effect of the artificial fish reef can be reflected to a certain extent.
