Threespine stickleback are a small, armored, three-spined fish famous in biology for their elaborate courtship and nest-building and their remarkable adaptability across fresh, brackish, and coastal waters. They aren't an angling target - they're a forage fish, prey for trout and other predators. On a location page, threespine stickleback are context about a water's small-fish forage base rather than a species to fish for.
