英文摘要	To ascertain potential differences in demersal fishery community structure between an aged artificial and a natural reef, four seasonal investigations based on netting gear and environmental factors were undertaken in the natural reef, the artificial reef, and adjacent sand bottom area in the offshore waters of Yantai, China, from August 2018 to February 2019. A total of 53 species were identified and collected, including 15 orders and 37 families. The species richness on seasonal average at the natural reefs area did not differ from that at the artificial reef, and both presented higher species numbers than the sand bottom area significantly (Kruskal-Wallis test, P<0.05). CPUE (catch per unit effort) were much higher at two reef areas than at the sand bottom area in each season (ANOVA, P<0.05), while the natural reef displayed greater CPUE value than that of the artificial reef in only spring and summer (ANOVA, P<0.05). To some extents, no overlap in dominate species composition among the three areas was shown, but the CPUE of each dominate species varied in the three areas. Reef fish Hexagrammos otakii and Sebastes schlegelii occupied the artificial reef with an apparent advantage over the natural reef and the sand bottom area in terms of CPUE. Biodiversity indices of bio-diversity, Shannon-Wiener diversity index (H′) displayed an order of: the natural reef>the artificial reef>the sand bottom area. No significant difference in Magalef species richness index (D) was detected between the two reef areas; and the sand bottom area exhibited a relatively lower D value. ANOSIM results show notably disparities in the community structures among the three areas due mainly to the differences in abundance and distribution of dominate species among the three areas, reflecting the roles of dominate species in structuring communities. Therefore, the artificial reef could increase the local demersal fishery yields, especially for reef fishes. However, the artificial reef had simpler community structure and less biodiversity than those of the natural reef. It will be a future issue whether artificial reefing can function as good as a natural one, to which long-term observation and investigation will be conducted.
