What's Biting at Korths Harbor
Activity ratings reflect typical feeding seasons — not legal seasons. Regulations, closures, and size/bag limits change; always check current CDFW regulations before keeping any fish.
Striped Bass
Morone saxatilis
Season: May – October
Baits: Anchovies, Topwater plugs, Swimbaits
Work troughs and rip currents on a moving tide. Dawn topwater in flat surf is the classic bite.
California Halibut
Paralichthys californicus
Season: April – September
Baits: Live anchovies, Swimbaits, Hair raisers
Drag baits slowly along sandy bottom near structure edges. Slow retrieve — halibut ambush from below.
Rockfish
Sebastes spp.
Season: April – December (check regs)
Baits: Shrimp flies, Metal jigs, Squid strips
Fish vertically over reef and kelp. Keep the bait just off bottom to dodge snags and hook quality grade.
Leopard Shark
Triakis semifasciata
Season: May – October
Baits: Squid, Mackerel chunks, Midshipman
Soak fresh bait on the flats during an evening incoming tide. Steel or heavy mono leader, circle hooks for a clean release.
Barred Surfperch
Amphistichus argenteus
Season: Year-round, best in winter–spring
Baits: Sand crabs, Gulp! sandworms, Motor oil grubs
Carolina rig in the first trough behind the shorebreak. Follow the tide in — perch feed where sand crabs wash out.
