Freshwater Trout & Hatches
Why do trout get selective during a hatch?
When a hatch produces a high density of one insect species on the water, trout key on that specific size, shape, and behavior. Other foods — including nymphs and other insects — get ignored because the focused feeding pattern is more efficient. Mismatched flies (wrong size or silhouette) get refused even when fish are clearly feeding.
