Few studies have been conducted on the attraction effect of artificial reef on fish in China. In this study, five different artificial reef models were put into an experimental trough to observe behavioral responses of fish Plectorhynchus cinctus. The results showed that without artificial reef models in the trough, Plectorhynchus cinctus preferred to stay in the left-edge areas (Areas A1 and A6) of the trough. The average occurring rate of fish in Areas A1 and A6 was about 61.60%, while the average occurring rate of fish inside the no-reef areas (Areas A3 and A8) was less than 5%. After the artificial models were put into the middle of Areas A3 and A8 of trough, average occurring rates of fish inside the reef areas (Areas A3 and A8) increased to 32.53% (Model B), 37.60% (Model C), 20.93% (Model D), 28.13% (Model E) and 29.20% (Model F), while those in the left-edge areas (Areas A1 and A6) of the trough reduced to 29.47% (Model B), 23.47% (Model C), 33.60% (Model D), 25.73% (Model E) and 42.93% (Model F). The results showed that all of five artificial reef models had obvious attraction effects on Plectorhynchus cinctus, and Model C had the best attraction effects due to its large available room and shade space.
