Title: Production by Brook Trout (<i>Salvelinus fontinalis</i>) in Four Streams in the Matamek Watershed, Quebec

These values represent the range of total fish flesh elaborated annually in these streams because trout was the only species present. Differences between streams in annual production and P: B ratios arose from variations in stream cover (and its effect on carrying capacity), recruitment, and total biomass. Variations in age-specific growth rates were not critical. Production in the two most productive streams was judged to be controlled by food, while in the other two streams lack of suitable cover for adult trout limited production.Read More
