Presents an analysis of juvenile salmon population growth and abundance data collected in the Campbell River estuary in 1994 to describe chinook habitat use, residency timing, growth, and potential competitive interactions between wild chinook fry, hatchery chinook, and other salmon species. Results are compared with previous information on habitat use, residence timing, and growth of wild and hatchery chinook. Analyses are presented in five parts: use of a discriminant function to predict the origin of chinook juveniles whose origin could not be field-determined; estimation of density and biomass of juvenile salmon in the estuary and a comparison of habitat use and residence timing; calculation of growth rates for wild and hatchery chinook; prediction of wild chinook fry weight based on total salmon biomass; and estimation of the carrying capacity of the estuary for juvenile chinook, coho, and all salmon species combined, based on mark-recapture and escapement-biostandard methods.
