    Abstract
    The growth rate and population structure of brown trout and juvenile salmon in two oligotrophic nursery streams in County Donegal in the North west of Ireland are compared, as well as data on sex ratios and sexual maturity. Details of the food of brown trout and salmon and the smolt run in 1967 are discussed. Estimates of fish population density and biomass for these rivers have been made and related to estimates made in two other rivers of similar terrain, one oligotrophic and the other eutrophic. Pre-migratory mortality rates in the salmon populations are discussed.
