Fishing notes

Coho, also called silver salmon, are known for aggressive strikes and spectacular jumps. They often hold in shallower, calmer water than chinook and will hit bright spoons and flashy flies.

In the Great Lakes, stocked coho are popular with trollers during the open-water season and move into tributaries in fall.

As with all salmon, rules are strict and vary by water, season, and whether fish are wild or hatchery-marked. Check the regulations before you fish.
