The purpose of the study was to investigate the economies of salmon fishing in Ireland. Essentially, it set out to answer the question "how valuable was the Irish salmon industry to the economy in 1970?" In order to answer this
question, the study tried to evaluate the economic impact of angling and commercial fishing on the various districts, determine the capacity of the industry for future development and provide information to assist in the more effective marketing of salmon and sea-trout angling. Although the survey was confined to 1970, its findings may be updated for subsequent years by means of the regularly published data on catches and numbers of licences, and by appropriate price indices
