Abstract

A systematic study of the ocean and zooplankton was conducted to record availability of zooplankton groups inhabiting coastal ecosystem of Bintulu and the ecological influences. Samplings were carried out on Southwest Monsoon season starting May 2022, July 2022, and August 2022 by vertical hauls of 150 μm mesh size with diameter of 0.3 meter. Data of water parameters (pH, temperature, salinity, dissolved oxygen, total dissolved solids turbidity, conductivity, nitrite, phosphorus, ammonia, total suspended solids, and chlorophyll-a), planktonic groups and abundance has been measured in five stations and resulted in the findings of ten zooplankton groups comprising hexanauplius, maxillopoda, malacostraca, polychaeta, sagittoidae, hydrozoa, appendicularia, tentaculata, bivalves, and scaphopoda. Population density ranging from of 351.15 ind./m³ to 3958.12 ind/m³ among five stations. Hexanauplius was found predominant (F= 100%), followed by malacostraca, and chaetognatha (F= 80%). It was also recorded that hexanauplius dominated the highest relative abundance (3159.93 ind./ m³) in Station 1, and lowest in Station 5 (343.72 ind./ m³). Result of this study revealed greatest range of diversity index was in Station 1 (0.5165), and lowest in Station 5 (0.1605). However, evenness index in Station 4, and Station 5 were both significantly higher than Station 1, Station 2, and Station 3 with accumulated number of 0.3407. Evaluation of correlation has accounted to a significant relationship between zooplankton populations and ecological parameters. The number of abundances correlated significantly with temperature, salinity, total dissolved solids, turbidity, conductivity, ammonia and total suspended solids measurements. Zooplankton richness found indicated fertility and favourable condition for planktonic and planktivorous survival in the coastal ecosystem of Bintulu, Sarawak.
