Objective(s): To collect burbot, longnose suckers, northern pike and flathead club in the Peace, Athabasca and Slave Rivers for gross pathology, contaminant, hepatic MED induction, retinol, metallothioasin, sex steroid, and gonad morphology analyses; to collect other species in conjunction with collection of target species for possible contaminant analyses; to record water temperature, surface pH, alkalinity and conductivity of each site; to measure, tag and release alive fish not required for contaminant analyses; and to prepare fish tissue samples in accordance with prescribed protocols and deliver them for analyses.
Project Description: The researcher will collect fish for analyses of contaminant body burdens. The sample size for each species will be 10-15 of each sex at each sampling site. Fish will be collected using set lines set in the evening and fished overnight. Blood samples will be taken from live fish and then tissues will be sampled and sent to labs for analyses. Gut contents will be examined and the fish will be aged.
