Benefit-cost analysis was used to provide a preliminary economic assessment of the Salisbury Lake fertilization project. The standard conditions B/C ratio for Salisbury Lake was 2.2:1 for a research level investigation. The B/C ratio for a regional production level fertilization project was estimated at 5.2:1 when stocking costs are included and 13.1:1 when stocking costs are excluded. Sensitivity analysis of the research level B/C model indicates the B/C ratio is relatively independent of variations in discount rate, fertilizer, labour and monitoring coasts; moderately sensitive to variations in site visits and stocking costs; and most sensitive to variations in input variables influencing yield estimates, fish size, catch/angler-day, and value of an angler-day. A validity check of the B/C model suggests predicted effort and catch estimates are reasonable compared to creel surveys on two lakes in the same management region.
