Growth and mercury content of roach (Rutilus rutilus, L.) perch (perca fluviatilis, L.) and pike (Esox lucius, L.) living in sewage effluent

Short-term exposure to municipal wastewater influences energy, growth, and swimming performance in juvenile Empire Gudgeons (Hypseleotris compressa)

“…1c). The observed increase in K is generally consistent with results from laboratory exposures of fish to domestic wastewater in another study (Liney et al, 2005b), and is a common trend in wild fish caught downstream of municipal wastewater discharge (Bull et al, 1981;Porter and Janz, 2003;Yeom et al, 2007;Tetreault et al, 2011). The most obvious explanation for increased K in this study and in natural fish populations exposed to domestic wastewater is related to the availability of excess nutrients (Yeom et al, 2007).…”

Bioaccumulation of Mercury in Various Fish Species from Orlík and Kamýk Water Reservoirs in the Czech Republic

“…Clearly proved increasing accumulation of Hg in muscle and liver over the lifetime of examined "sh could be regarded as an indication of contamination (Bull et al, 1981;Rincon et al, 1987). A linear model provided the best "t to the data in nearly all cases, except for the Hg content in muscle of roach where the second-order polynomial dependence on the age of "sh was recognized (Figs.…”

Fishing, Consumption, and Risk Perception in Fisherfolk along an East Coast Estuary

“…The scientific community has shown that mercury levels vary in fish as a function of size and age of the fish (bigger, older fish have higher levels of contaminants) and trophic level (predatory fish accumulate more than nonpredators; Cutsall et al, 1978;Bull et al, 1981;Burger et al, 1992), but this information is not helpful if the general public is unaware of these differences (Tollefson, 1989;Clarkson, 1990).…”
