The green mussels, Perna viridis is an edible mollusc with culture potential for seafood restaurants in Malaysia. The aim of this study was to investigate the in situ P. viridis monthly growth in Santubong River, Sarawak by using two different substrates which are the nylon ropes and window glass apparatus being immersed in the river by tying ropes to the wood platform of the fish cage starting from September 2007 and ending in February 2008. Monthly growth data shows that after six months in situ study, the mussels reached shell length ranges from 1.66 cm to 3.20 cm and 1.21 cm to 2.84 cm for the smooth and rough window glass respectively. Green mussels' monthly growth for ropes method was considered failed due to ineffective methods when no mussels attached on the ropes after November 2007. Gut content analysis was done on 25 mussel samples in order to determine the food uptake of more than 20 μm. The dominant food uptake was diatoms with dominant genera of Cydotella sp. and Coscinodiscus sp. whereas the dominant zooplankton taxon was Copepods. Green mussels also assimilate two benthic organisms and eight chlorophyta genera as found in this study. The population class size at the base of Santubong Bridge pillar was dominated by Class 2 (6.68 cm to 9.67 cm). P. viridis shell deformation was found in a few quantities from the mussels collected at the bridge pillar such as continuous, discontinuous and unidentified shell deformation.
