Fundamental research problems in the management of Atlantic salmon, Salmo salar L., in Atlantic Canada
There are two fundamental types of research problems facing the management of Atlantic salmon in Atlantic Canada. First, there are problems associated with assessment of individual and mixed stocks: these can be divided into estimating optimal spawning requirements, estimating current spawning escap...
