Effects of pollution and parasites on biomarkers of fish health in spottail shiners (Notropis hudsonius Clinton)

Effects of pollution and parasites on biomarkers of fish health in spottail shiners (Notropis hudsonius Clinton)In this study, seven non‐specific biomarkers were compared in Spottail Shiners (Notropis hudsonius Clinton) from localities receiving urban and industrial effluents and relatively clean localities in the St Lawrence River, Canada. Pigmented macrophages are involved in a variety of functions including the detoxification and recycling of exogenous and endogenous material, responses to foreign material or infectious agents, and antigen recognition. Pigmented macrophage aggregates are focal accumulations of pigmented macrophages found in the spleen, kidney, liver and other organs of fishes. They may respond to toxicants or exposure to infectious agents such as viruses or bacteria either by increasing in number and size or by changing the shape of the aggregation. It was hypothesized that differences would be seen in these biomarkers in fish from polluted localities compared to fish from relatively cleaner ones and these changes would be more pronounced in heavily infected fish.
