The Eel River Pikeminnow Derby started on July 1, and is running through August 31, with $2,500 in cash prizes for anglers helping remove this invasive predator from key stretches of the Eel system. Categories include most fish over 6 inches, most over 12 inches (with tape in photo), and longest single fish. There’s also a kids drawing with eight $50 winners.

Fishing is restricted to artificial, barbless-only gear — no bait. Open zones include the South Fork below the Humboldt County line, the mainstem from Dos Rios to the Van Duzen, and the Van Duzen from Grizzly Creek down. There’s no bag limit on pikeminnow, but wasting fish is a violation and will get you disqualified.
