Objectif(s): To provide detailed baseline data on aquatic biota, and limnology of the area, as well as habitat assessment in general; to provide information from fish studies on the species present/absent in the area and population estimates; to evaluate fish habitat and the degree of utilization for each fish species will be assessed; and to document fish bilological parameters, investigate fish diets, and obtain fish tissues for determination of background metal levels.

Description du projet: In project area creeks & streams, fish presence/absence and/ or densities will be obtained by electrofishing representative habitat & the setting of baited minnow traps. Each fish caught will be identified, measured, weighed & sexed, & condition will be noted. Furthermore, in order to assess background tissue metal levels, ten specimens of each species must be sacrificed in order to obtain the required muscle and liver tissues for analyses.
