Objectif(s): To provide detailed and sometimes supplemental baseline data on habitat utilization and fish community structure in the Snare Rapids headpond and the lower and upper sections of the river, as well as habitat assessment in general; to evaluate fish habitat and the degree of utilization for each fish species will be assessed; to document fish biological parameters (length, weight, condition, sexual maturity, age, etc); to investigate fish diets; and to obtain fish tissues for determination of background metal levels.
Description du projet: In this study fish presence/absence and/or densities will be obtained by electrofishing representative habitat and the setting of baited minnow traps. When these two methods are not practical gill nets, trap nets, and/or beach seines will be employed. Each fish caught will be identified, measured, sexed and condition will be noted. Ten specimens of each species from each site (up to 10) will be sacrificed for background tissue metal levels.
