As part of the Pacific Salmon Endowment Fund Societys Englishman River recovery plan, a mark-recapture study was conducted in the spring of 2002 to assess coho and steelhead smolt production. The Community Fisheries Development Centre (Nanaimo) contracted the BC Conservation Foundation to complete the study steelhead smolt component. Estimates of the number of steelhead smolts emigrating from the Englishman River between April 16 and June 8 ranged from 2,403 (ML Darroch estimate, 95% confidence limits: 1,365-3,442) to 2,703 (pooled Peterson estimate, 95% confidence interval: 1,784-3,624). A Schaefer estimate of 2,597 was also calculated. The smolt group was composed of 77.6% two year olds, and 22.4% three year olds, and had mean lengths and weights of 167 mm (SD 17) and 43.2 g (SD 14.8), respectively. Recommendations include continued monitoring for at least one generation, preferred trap sites, and budget allocations to deal with high trap maintenance periods and late migrants.
