Fishing Days to Monitor Populations

Grayling fishing days are one of the best ways to monitor populations; by allowing anglers to fish for grayling for a specific number of hours on a specific day.

All grayling captured are recorded along with their weight, sex, length and a sample of scales can be taken for analysis (GRT can help with ageing scales). From this, information on growth rates, sex ratios and condition of populations can be calculated.

Because the number of hours fished is standardised or recorded, results from different events can be compared. Grayling fishing days are run by a number of clubs and organisations, a selection are listed below along with details and summary reports.
