Assessing the status of Scottish Atlantic salmon (Salmo salar L.) stocks using reported catch data: a modelling approach to account for catch and release in the rod and line fishery : Scottish Marine and Freshwater Science Vol 5 No 11
This report describes a modelling approach which has been developed to correct the reported catch of Scottish rod fisheries by accounting for recaptures associated with these data. In the absence of direct counting systems, the abundance of Atlantic salmon stocks in Scotland is generally estimated i...
