Distribution And Abundance Of Benthic Molluscs In Coastal Waters Of Northwestern Penang Island

The study was surveyed from October 2010 to September 2011 at four sampling sites—Teluk Bahang, Teluk Aling, Teluk Ketapang, and Pantai Acheh. At each site, benthic molluscs, sediments, and water quality parameters were sampled every 2 months, at intervals of 200 m with 6 sampling points. A total of...

At each site, benthic molluscs, sediments, and water quality parameters were sampled every 2 months, at intervals of 200 m with 6 sampling points. A total of 21 families, 21 genera, and 25 species were recorded with mean abundance of 613.6 molluscs/m2.
