註釋Presents results of a chinook salmon stock assessment study conducted in 1997 on the Klinaklini river system, coastal British Columbia. Objectives of the study included: evaluation of the suitability of using a fishwheel to index the abundance and timing of chinook returns to the Klinaklini system; estimation of total chinook escapement and spawner distributions; collection of biological data for this stock; and recording of environmental information. In the field study, a counting fence was used to enumerate fish on Mussel Creek, a live mark-recapture study was carried out by tagging chinook at the fishwheel and recapturing fish at a Mussel Creek fence, radio telemetry was used to determine distribution of radio-tagged spawners, and a rotary screw trap was used to determine downstream migration of juveniles. Results presented include estimated total return of adult chinook to the Klinaklini, fish age and length distribution, and fishwheel performance.
