In 1973, the Foyle Fisheries Commission invited a team of fisheries experts from North America to examine the Foyle and its tributaries, and the state of health of its fish stocks. The research group spent the whole of July 1973 looking at the area in detail, interviewing "all those with a direct interest", and examining all relevant records. The fishing industries off the western coast of Donegal are included in the report. There followed two years of further work, culminating in this report. The report includes detailed recommendations on practical measures which the Foyle Fisheries Commission could take to guarantee the future of the fish stock and its habitat in the future.
