The ocean whitefish isn’t usually the star of the sportfishing world, but it’s a fantastic fish for filling the cooler and the dinner plate. As an aggressive bottom fish that puts up a surprising fight, they are fun to catch and even better to eat.

This guide covers everything you need to know to successfully target Caulolatilus princeps.

Overview and Habitat

The ocean whitefish, also known as the California whitefish or Blanquillo, is a species of tilefish native to the eastern Pacific. Its habitat stretches from British Columbia, Canada, down to Peru, with large populations concentrated along the coast of California and its offshore islands and banks, like Cortez Bank.

They are primarily bottom dwellers, preferring rocky reefs, high-relief structure, and the edges of kelp beds in water from 30 to over 300 feet deep. These rocky reef habitats provide refuge from predators and a steady supply of food.

How to Catch Whitefish: The Complete Guide

Best Time of Day to Fish
Whitefish bite throughout the day, but the action is often best during the morning hours. This is when they are most actively feeding around rocky reefs and kelp lines. Yes, you can catch whitefish at night, especially in deep water around offshore structure, where they will still actively feed.

Advanced Rigging and Gear Setup

  • The Best Rig: The undisputed king for ocean whitefish is the dropper loop rig (also known as a “double dropper loop”). This setup allows you to present two baited hooks suspended above the weight, keeping them directly in the strike zone and minimizing snags.
  • Hooks: Use a small hook to match their small mouth. A size 1, 1/0, or 2/0 heavy-gauge wire hook is perfect. Heavy wire is crucial to prevent the hook from bending or breaking in their tough mouths.
  • Line Choice: A 12 lb to 20 lb test monofilament or fluorocarbon line is ideal for most situations. For deeper water (over 200 feet), braided line (20-30 lb test) with a fluorocarbon leader is superior. Braid’s lack of stretch allows you to feel subtle bites from the deep.
  • Rod and Reel: A 7- to 9-foot medium-action rod provides the right balance of sensitivity and power. Match it with a conventional or spinning reel with a smooth drag system.

Best Baits, Lures, and Scents

Whitefish are not picky eaters. Their diet consists of small invertebrates, crabs, shrimp, and small fish like anchovies.

  • Best Natural Baits:
    1. Squid: Strips or whole small squid are durable and highly effective. This is the top choice for many charter boats.
    2. Shrimp: Both live and dead shrimp work exceptionally well.
    3. Anchovies: Pinhead anchovies or chunks of larger ones are excellent, though they can be softer and come off the hook more easily.
  • Best Lures:
    1. Metal Jigs: Small, flashy metal jigs (1-3 oz) worked vertically off the bottom can trigger aggressive strikes. Let the jig hit the bottom, then lift it a few feet and let it flutter back down.
    2. Plastic Grubs: A small plastic grub or swimbait threaded onto a leadhead jig is another great option that imitates their natural prey.
  • The Scent Advantage: Saltwater fish, including whitefish, rely heavily on scent. Adding a commercial fish attractant (like Pro-Cure in squid or shrimp scent) to your bait or lure can significantly increase your bite rate, especially when the bite is slow.

Fishing Tactics: From Pier to Deep Water

  • Find the Structure: The number one rule is to find hard bottom. Use a fish finder to locate rocky reefs or high-relief areas.
  • Suspend Your Bait: This is the most critical tactic. Whitefish are not true bottom feeders; they feed in the water column above the reef. After your sinker hits the bottom, reel up 5 to 10 feet. This places your baits perfectly in their feeding zone.
  • Catching Whitefish from a Pier: While less common, you can catch whitefish from piers that provide access to deep water and rocky structure. Use a dropper loop rig and cast as far as you can toward any submerged rocks or kelp.
  • How to Get Whitefish to Bite: If the bite is slow, try twitching your rod tip gently. This subtle movement can attract attention. If that doesn’t work, add scent to your bait.

Handling and Preparation

When landed, be careful of the sharp, serrated edge on their gill plate. Firmly grip the fish through the eye sockets to handle it safely.

The flesh of ocean whitefish is firm with a mild taste, making it excellent for baking, frying, or grilling.


Frequently Asked Questions

Are ocean whitefish good to eat?

Yes, they are excellent eating. The meat is white, firm, and mild, with no “fishy” or bitter taste.

What is the best bait for whitefish?

Strips of squid are the most popular and effective bait due to their durability and scent.

Are whitefish bottom feeders?

No, they are more accurately described as “bottom-oriented.” They live near the bottom but feed on prey in the water column just above it.
