asked the Secretary of State for Northern Ireland what is the method used by the Foyle Fisheries Commission to estimate the total rod catch in its area for salmon, grilse and sea trout.
pursuant to his reply [Official Report, 13th November 1978] gave the following reply:The estimated total rod catch is obtained by multiplying the average catch as reported by licence holders by the total number of licences issued.
asked the Secretary of State for Northern Ireland how the num- ber of salmon and grilse and sea trout reported by fishing clubs in the Foyle area is being caught by their members compares with the estimate of the Foyle Fisheries Commission for a similar number of anglers on the same water.
pursuant to his reply [Official Report, 13th November 1978] gave the following reply:From the information available it is not possible to estimate the number of anglers using club waters and therefore no comparison with club catches can be made. Full details of reported catches on each river in the Foyle area and also catches by clubs are available in the 26th annual report of the Foyle Fisheries Commission 1977.
