Abstract

This study was conducted at five stations at Tanjung Aru reef. Status of the reef was assessed using the Reef Check method which comprise of the fish belt transect, invertebrate belt transect, point sampling and coral impacts. A vertical substrate profile was examined by laying a transect-line vertically and the substratum type was recorded using the Line Intercept Transect (LIT) method. Sediment deposition rate was studied by placing two sediment traps at each depth of 4m and 8m where the transect-line was laid. Traps were replaced every 30 days for three months. Collectedsediments were further examined using the grain size analysis method. A total of 36 targeted fishes were recorded at 4m and 51 targeted fishes at 8m while the total number of invertebrates recorded at 4m were 83 individuals and there were only 9 individuals at 8m. Out of the five stations surveyed, coral coverage at stations 3 and 5 were good while the other stations were categorised as "fair". Station 2 had highest degree of coral impacts with a total degree of 7. Fishing activities were the main impacts because fish nets, craters from blast fishing and illegal fishing method wereobserved in the study area. The mean sediment deposition rate at 4m was 3.98±0.76mg/cm²/day while at 8m it was 7.61±1.72mg/cm²/day. Lowest rate recorded was 2.87mg/cm²/day in station 1 at 4m and highest was 9.50mg/cm²/day in station 5 at 8m. The grain size analysis shows that the sediments in the study area are either categorized as "fine" or "very fine silt" according to the Udden-Wentworh (1922) size class scale. It is suggested that Tanjung Aru reef be gazetted into a marine park to prevent overfishing and further damage from both illegal and destructive fishing methods.
