Fraser River Action Plan 3rd Research Workshop General Synopsis • several potential sentinel species occur in the upper Fraser; few were found in sufficient abundance and distribution • by virtue of capture success, peamouth chub represented the best species for monitoring • although mature chub were collected from the reference zone, limited numbers were collected from either near-field zone • despite substantial effort, capture success in the near-field zones appeared hampered by a lack of suitable sampling habitat • regardless of the limited field data, there was evidence which suggested that effluent from mills A and B were capable of eliciting physiological responses in laboratory and resident fish species (immature chub) Page 32
Fraser River Action Plan 3rd Research Workshop How Results Affect Future Management • near-field evaluations of fish responses have been difficult in the Fraser River • need to continue to try to develop near-field evaluation techniques for sites where there are dramatic seasonal changes in flow and differences in habitat • the success of using peamouth chub for monitoring the upper Fraser River is uncertain: 1. larger than many cyprinid/cottid species and its capacity for large-scale movement is unknown 2. inability to capture chub in near-field zones restricts use of this species to far-field zones, or mills located further downstream of Prince George where peamouth chub are more abundant • although there are problems associated with peamouth chub for monitoring the near-field zones, use of small fish species for monitoring has been successful in other studies: lake chub - Athabasca River near Whitecourt, Alberta spoonhead sculpin - Athabasca River near Hinton, Alberta trout-perch - Moose River system, Ontario • general approach should be considered a viable alternative to monitoring large, mobile fish species Page 33
