Fishes and macroinvertebrates(FM) were sampled respectively in ShangSanheng artificial reef area (marked by B) in May,Sept. of 2007 and Mar. ,May,Jul. of 2009 by trawl-net,and XiaSanheng artificial reef area(marked by A) from Jan. to Aug. of 2009 by multi-mesh gill-nets around Sanheng artificial reef waters,in order to assess resource enhancement effects of the deployed artificial reefs(ARs). Several control sites were chosen for better explanation on habitat restoration function by ARs. CPUE,Margalef species richness index,commercial species variation and Whilm species diversity index were used to discuss the change of FM resource. Result shows that:(1) A area: average CPUE’s significant differences were found neither between ARs and soft bottom habitat nor between ARs and rocky reef habitat(P 0. 05). However, the same index value from Feb. to Aug. between ARs and soft bottom habitat,was quite different(P 0. 05). Species richness level of ARs was obviously higher than that of the soft bottom habitat by 60. 2% (P 0. 05),no differences existed between ARs habitat and Rocky reef habitat(P 0. 05). Both ARs habitat and Rocky reef habitat share more commercial species than soft bottom habitat(P 0. 05),and they seemed to be equal by chance to attract commercial species(P 0. 05). As to species diversity,it was exactly the same as commercial species differences explained above,namely,which is equal between ARs habitat and Rocky reef habitat,and better than soft bottom habitat. (2) B area: CPUE in AR area was obviously improved by 2. 05 times after deployment(P 0. 05) and 2 times higher than that of control site(P 0. 05). Species richness level has been improved by 25. 3% after reef deployment,though no significant differences were found between them. However,it did have a better level than control site by 31. 3% higher(P 0. 05). 5 more commercial species were sampled in AR area after reef deployment compared to its original number(P 0. 05),and about 4 more species were sampled in AR area than control site after reefs were set. The diversity index in AR area has improved to a certain level,better than before and control site,though they appeared to be not so quite different(0. 05 P 0. 1). It is concluded that resource level and community structure have been improved a lot in both AR areas by comparison to its original level and control site level. The Sanheng artificial reefs have become a new habitat for more species and more individuals.
