Description: This session will (i) synthesize the current state of knowledge on the effects of pollution and contamination on Indo-Pacific fishes, and (ii) identify future areas of research and monitoring that will inform the effective management of pollutant and contaminant sources. The coastal environment is the ultimate sink for many pollutants and contaminants, and their associated breakdown products. Pollutants and contaminants can enter the coastal environment via aquatic and atmospheric transport from diffuse sources such as agricultural runoff, urban runoff and shipping, and from point sources such as shipping ports, industrial waste, sewage outfalls, and storm water drains. The presence of pollutants and contaminants can affect the quality and uses of the coastal environment including direct uses such as fisheries, tourism, and recreation. In this session, we will examine the effects of sedimentation, eutrophication, and contamination on freshwater, estuarine and marine Indo-Pacific fishes, including fish species important for human consumption. Pollutants and contaminants that will be considered include, but are not limited to suspended sediment, nutrients, pesticides, metals, hydrocarbons, microplastics, and antifouling paints. Field and laboratory approaches of interest include (i) bio-accumulation studies, (ii) studies on biomarkers of exposure and effect, and (iii) studies on bio-indicators of fish health. Methods of interests include chemical, genetic, molecular, physiological, (eco-) toxicological, behavioural and histological ones. Of particular interest are studies that have considered the ultimate effects of exposure to pollutants, such as growth, reproduction and mortality of individual fish, as well as flow-on effects on fish population and community structures.

Expected Audience: The expected audience for this session include fish and fisheries researchers, managers and community members interested in learning about the potential effects of pollution and contamination on Indo-Pacific fish species. We envisage contributions from researchers who are working on a range of pollutants and contaminants in freshwater, estuarine and marine environments across the Indo-Pacific, using different approaches and methods, to synthesize the current state of knowledge. An important component of our session is to build on this synthesis, and identify future areas of research and monitoring that will inform the effective management of pollutant and contaminant sources.
