Tackle & technique
- Surfperch
- Surfperch feed in the troughs and holes within about 30 feet of the waterline, just outside the first set of breakers. Cast a two-hook high-low or Carolina rig with size 4 to 2 hooks and a 1 to 6 ounce pyramid sinker and let the surge work it through the trough. Fish the incoming tide on beaches with a steep drop, and switch to jetties, pilings and bays when the surf is too big.
- Pacific halibut
- Halibut sit on sand and gravel bottoms near drop-offs, bars and pinnacles, most often in 90 to 500 feet in Alaska and on the shelf off Washington, Oregon and far northern California. Anchor up-current of a likely edge and fish herring, squid, octopus or a salmon head on a circle hook with 24 to 32 ounces of weight, or bounce a large jig on the bottom. The best bite usually comes in the hour around slack tide.
- Cabezon
- Cabezon sit in rock crevices, kelp beds and jetty boulders from the intertidal zone to about 100 feet and feed mostly on crabs and small fish. Fish a fish-finder rig with sand shrimp, squid or crab right on the bottom in the rocks, or drag a lead-head grub slowly through the kelp. Expect snags, and do not eat the roe, which is toxic.
