Production studies as a focus for assessing juvenile Atlantic salmon populations / by R.G. Randall. : Fs70-8/81-76E-PDF

"Proper management of Atlantic salmon during the freshwater phase of its life cycle will depend to a large extent on our knowledge of how salmon production in nursery streams is affected by different environmental and biological features. Production here is used in a defined biological sense, i.e., it is the rate at which biomass is being produced in the natural environment. At present, juvenile salmon populations are monitored by estimating population densities at a large number of sites once annually. I am proposing in this document that this field program should be modified so that long-term studies of production can be made; production estimates could then be used as a more effective focus for the annual assessment of the state of juvenile Atlantic salmon populations. General field procedures required for estimating the production rate of salmon in eastern Canadian streams are discussed"--Abstract.
