| Abstract | The production rate of juvenile Atlantic salmon (Sa/rna sa/a" and brown trout (Sa/rna trona) was estimated atasite in Mountain Brook, asmailtributaryofRiverPhilip, Nova Scotia. S. salarwereusually more abundant than S. trona, but growth rate of S. lruna was Significantly grealer. For both species, seasonal growth was restricted to a six month period (May to October). For nine sampling dates between June 1966 and June 196810lal salmonid biomass averaged 3.6 g m ' l (range 1.2-5.6 g mol), Production rate was similar for both species; total production was 3.5 g m" y' from June 1986 to June 1987 and 5.9 g m-I y' from June 1987 to June 1988. Although S. truna are not native to eastern Canada, a naturalized population has become established in River Philip, and they are cohabiting successfully with native S. salar. Future studies on population interactions and possible range extensions of introduced S. truffa would be beneficial for the management of salmon ids in eastern Canada. |
