Building on the Pacific Salmon Endowment Fund Society Englishman River recovery plan, a
second year of mark-recapture was conducted in the spring of 2003 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. The pooled
Peterson estimate of steelhead smolts emigrating from the Englishman River between April 12
and June 3, 2003 was 2,657 fish (95% confidence interval: 1,756 and 3,557). The Schaefer
estimate was 2,585. Slightly older and smaller than fish in 2002, the 2003 smolt group was
composed of 71.4% two year olds and 28.6% three year olds (n=70), and had mean lengths and
weights of 159 mm (SD 16) and 36.9 g (SD 12.1; n=131), respectively. Recommendations
include continued monitoring and improved trap maintenance during high water and/or heavy
wind periods.
