Each year during the months of September and October, Pennsylvania’s wild brook trout begin spawning. The start of the spawn is different in every stream and is typically touched off by a change in water temperature. During the spawn, the male brook trout begin to change color. The orange on their fins and bellies becomes vibrant as they prepare to join females on redds. There is a lot of controversy around whether or not it is ethical to fish for brook trout while they are spawning. Some folks feel that fishing has little to no impact, as long as careful catch and release is practiced. Others believe that it is the worst thing a fisherman could take part in and avoid fishing entirely.
