Hatches on the River Annan

For the majority of the fly fisherman who visit the Annan they will be reliant on mayflies, stone flies and sedges to prompt the trout into feeding. There will also be a variety of terrestrials about as well although only three - hawthorn, black gnats and daddy long legs - are consistently important. The calendars below represent the times when these flies will be seen by anglers and most available to trout. Anglers should remember that whilst we are on the lookout for insects in the air the trout are just interested in food.
The majority of the food items that the trout eat will be subsurface and nymphs, shrimps and fish will make up the biggest part of the Annan trout's diet. Assume the fish are feeding nearer the bottom on nymphs but the calendars can still be used as the types of nymphs that are available will be the ones that are most active and these are the ones which are closest to hatching. If in doubt you cannot go much wrong with either a GRHE or a PT when fish are seen to be feeding but on something that is sub-surface.
