Diversity of fish and macrobenthos at the coastal area of Tanjung Kidurong Power Plant (TKPP), Sarawak, Malaysia

The regular assessment of faunal diversity near the energy power plant has gained interest many researchers. activity and effluent discharged from have remarkably stressed adjacent assemblage alpha biotic community surrounding plant. Hence, this study aimed to assess fishes benthos in bordering areas Tanjung Kidurong Combined Cycle Power Plant (TKCCP), Bintulu Sarawak. investigation was conducted coastal area 2019 2020. Different ecological indices such as evenness index, Margalef richness, Shannon-Weiner index were implemented, along with cluster analysis other stations. A number 141 fish individuals recorded, containing 40 species 19 families. In addition, 13182 communities six classes 37 identified. percentage 78 comprised fishes, while 22% identified crustaceans. Among addressed, Foraminifera major group (74%), followed by bivalve (10%) Scaphopoda (7%). Compared SEB2, 3 & 4, SEB1, nearest plant, recorded highest species, indexes. Cluster analysis, PCA, nMDS suggested that SEB3, SEB4 had similar biodiversity compositions. indicates SEB1 possesses a distinguished value This would provide future researchers vital documentation evaluate impact thermal discharge on Bintulu, Sarawak, Malaysia.
