Description :
A number of useful models are available to help predict these global environmental changes acting through alterations in stream discharge and periodicity, ice-free period, water temperature, epilimnial depth and volume, dissolved oxygen level and hypolomnetic depletion rate, all of which are major determinants of sport fish habitat quality and quantity. There is great regional difference in the direction and severity of probable effects of global environmental change within the province, in some areas negative and in others positive. These are reviewed and suggestions made regarding management policies required to meet their challenge.
