In subtropical and tropical waters, the green-lipped musselPerna viridisis predominant, and it can provide a significant contribution to biological monitoring programmes in the Asia-Pacific region. While many studies have reported various responses (molecular, cytological, histological, physiological, and behavioural) in the green-lipped mussels to reflect contaminant levels in the marine ecosystems, there has been no attempt to relate the changes in the feeding response of the mussels to different environmental conditions except for the study of condition indices. Recent studies show that fatty acids can be used as a tracer for trophic relationships in an ecosystem. As the feeding response of an organism is closely related to the state of the environment, it may thus be possible to use the fatty acid profile of the organism as an indicator for environmental conditions. This research aims to investigate the applicability of the fatty acid profile in green-lipped mussels as an indicator of pertinent environmental conditions in the marine environment. Specifically the objectives are to:examine the spatial and temporal changes of the fatty acid profile in green-lipped mussels collected from contrasting environmental conditions; andelucidate if such changes are environmentally or genetically induced.
