Analysis and Evaluation of the Recreational Fishing Grounds
The methods used to create the weighted surface of the recreational fishing grounds is identical to that used for the commercial fisheries with one exception. The analysis used to create the commercial fishing grounds were weighted by multiplying stated importance values from the interviews by the proportion of in-study region landings (both by landing port and by fishery), and more specifically, by ex-vessel values for those landings. In contrast, no weighting occurs in the calculation of recreational fishing grounds, but rather, the analysis is done using only stated importance values from the interviews. No weighting occurs for the obvious reason that ex-vessel values do not exist for recreational fishery landings.
