A field experiment was designed to assess the attraction of artificial seagrass on fishes. Artificial seagrass units were tied with 6 square metal mats, 1m x 3m, and were submerged on a plain area that only contain silt and sand nearby jetty of UMS, Sepanggar Bay. The fish identification was made up to genus level and fish abundances were recorded with the aid of photos. The characteristics of every fish were also observed during dives. Two tests were applied by using Shannon Weaver Index and Pielou Evenness Index to know the fish diversity in the area. As the result the diversity of fish in the area was high but had decreased compared to the study in the previous year. The interpretation of these data is that artificial seagrass successfully attracts various fishes, with the most occurrences was Caesio sp .. However the numbers of fishes in the area decreased based the data in previous study in this area, with some of the factors such as the condition of the artificial seagrass units in the area such as all the seagrass blades were lying on the seabed and the environmental problem such as algae bloom.
