  Physicochemical parameters influence the vertical spatial distribution of microbial communities in any water bodies. Based on this perspective, a study on physicochemical parameters and bacterial community was carried out from five stations on January-June 2009 at the Kuantan estuary of Pahang, Malaysia. The temperature was ranged from 25.01-27.48°C, salinity fluctuation observed 0.03-25.84 ppt, Dissolved Oxygen (DO) 6.10 to 10.73 mg L-1, specific conductivity ranged from 0.10 to 42.43 mS cm-1, Total Dissolved Solids (TDS) ranged from 0.05 to 26.36 g L-1) and pH varied from 5.69 to 8.11 and chlorophyll a ranged 0.01 to 1.14 μg L-1. The nitrite concentration was higher at St. 5 (0.19 mg L-1) followed by St. 4 (0.16 mg L-1) and it was lowest at St. 1 (0.13 mg L-1). Similarly, high phosphorus content (0.17 mg L-1) was found at St. 4 followed by St. 5 (0.16 mg L-1) while, it was lowest at St. 1 (0.08 mg L-1). Out of 19 isolated bacteria most dominant bacteria were Citrobacter freundii followed by Leuconostoc sp. and Staphylococcus xylosus. High bacterial colony (cfu mL-1) was observed at St. 4 (570 cfu mL-1) in water column followed by St. 5 (490 cfu mL-1). In contrary, it was lowest at St. 2 (213 cfu mL-1). Meanwhile, the highest bacterial colony in sediment was observed at St. 4 (390 cfu mL-1) followed by St. 5 (333 cfu mL-1). It was lowest observed at St. 2 (167 cfu mL-1). Nevertheless, a continuous monitoring of water quality is needed in this estuary especially at St. 4 and 5 which could be alarming in the long run due to deposition of nutrients from the outlets of fishing villages and industry sources.

  A study was conducted on physico-chemical parameters and bacterial pollution in Orbicularia orbiculata (Wood, 1828) and Anadara granosa (L.) at Pahang estuary from January to February 2009. The temperature was ranged from 28.00-29.87°C, pH 7.79-8.10, specific conductivity 51.49-55.89 mS cm-1, salinity 18.74-30.10 ppt., TDS 33.63-39.59 g L-1, DO 6.80-7.50 mg L-1. The nitrate concentration was found to be highest at Station 3 (14.09 μg at N-l) and lowest at Station 2 (7.04 μg at N-l). The nitrite concentration showed highest concentration at Station 4 (7.07 μg at N-l) and lowest concentration at Station 2 (1.67 μg at N-l). Whilst the phosphate content was higher (10.78 μg at N-l) at Station 3 and lowest at Station 2 (2.34 μg at N-l). A total of 60 Orbicularia orbiculata and 40 Anadara granosa samples were subjected to microbiological analysis. The bacteria were isolated using non selective agar such as TSA agar and selective agar before they were identified using conventional methods in combination with API identification kit. A total of nine bacterial species were identified from Orbicularia orbiculata. They were Escherichia coli., Aerococcus viridans 1, Aerococcus viridans 2, Gemella morbillorum, Kocuria varians, Micrococcus sp., Pseudomonas aeruginosa, Staphylococcus sciuri, Streptococcus pneumoniae. Whilst, Nineteen bacterial species were identified in Anadara granosa such as Aeromonas hydrophila group 1, Aerococcus viridians 1, Aerococcus viridans 2, Chromobacterium violaceum., Enterobacter gergoviae, Erwinia sp., Escherichia coli, Enterococcus avium, Gemella morbillorum, Kluyvera sp., Vibrio fluvialis, Vibrio cholerae, Vibrio parahaemolyticus, Lactococcus lactis, Leuconostoc sp., Staphylococcus capitis, Staphylococcus lentus, Staphylococcus epidermidis, Staphylococcus xylosus. The finding indicates that the edible mollusc of Pahang estuary was polluted with pathogenic bacteria which could be harmful for human consumption.

  Artificial seagrass plays an important role for the distribution of benthic organisms and fishes. Based on this perspective a study was conducted in the Sepanggar Bay located in the Northern part of Kota Kinabalu, Malaysia from November 2006 to February 2007 to determine the potentiality of artificial seagrass as an alternative habitat for marine fishes. The artificial seagrass area is located approximately 100 m from the coastline at the depth between 6 and 10 m and made up of Dorken Advance Engineer Rubber which was tightened on a square 1 x 3 m metal mat. The sampling process was done by capturing photos and video recording. The picture of the fishes was taken as many as possible to increase the accuracy and precision of fish identification. A total of 497 fish species belong to 17 families were observed in 5 sampling periods throughout the study. Out of 17 families, Pomacentridae was dominant with 25.55% (127 individuals) followed by caesionidae with 22.13% (110 individuals). It was observed that Caesio sp. from a family Caesionidae was dominant genus in the artificial seagrass area, followed by Chromis sp. and Pomacentrus sp. from a family Pomacentridae. Overall Shannon diversity (H’) value of 2.5315 indicates artificial sea grass could play a vital role as a nutrient rich habitat for marine fishes.
