Eurasian perch

Example of a Prey-Fish Indicator Yellow Perch Analyses of total mercnry in whole bodies or axial muscle tissue of age-1 yellow perch have provided a useful measure of MeHg concentrations in food webs of many North American lakes. This widely distributed species inhabits lakes and reservoirs across mnch of the north-central, northeastern, and eastern United States and across the central and eastern provinces of Canada (Scott and Crossman 1973 Becker 1983). An ecologically similar congeneric species, the Eurasian perch Perea fluvi-atilis), is distribnted across much of Europe and northern Asia (Thorpe 1977). 

Bilberg and collaborators studied the effects of sUver nanoparticies on the breathing of the Eurasian perch. The final results revealed that exposure to silver nanoparticies reduced tolerance to hypoxia (oxygen deficiency) (Bilberg et al., 2010).

The genus Perea has three species Perea fluviatilis, a Eurasian species the yellow perch, Perea flaveseens of North America and Perea shrenki of Asia. All three species are generalized forms that probably represent the ancestral type from which the other species were derived.
