Saltwater · Year-round; a mainstay of Southern California party-boat seasons
Ocean Whitefish
Caulolatilus princeps
The party-boat professional of Southern California — ocean whitefish school over island rockpiles by the hundreds, bite squid strips all day, and eat like the tilefish they are.
Seasons · Peak
Identifying features
- A tilefish, not a true whitefish: torpedo body, bluish back, silver-white belly and a long continuous dorsal fin
- Yellow-tipped tail lobes and yellow markings on the dorsal fin; pectoral fins are yellowish
- Mouth is moderate with fleshy lips; no barbel, no spines to fear
- Colour pales to almost white after capture — the source of the name
- Look-alike: freshwater lake whitefish are a salmon-family fish of northern lakes; ocean whitefish are warm-water marine tilefish
Habits
- A bottom-oriented tilefish: hovers and picks over rocky banks and island slopes in 60-300 ft
- Feeds on squid, shrimp, crabs and small fish right on the bottom
- The backbone of Southern California half-day boat catches alongside rockfish
- Schools loosely over hard bottom; where you catch one, you'll catch more
Distribution
Where to find them
- Rocky banks and slopes around Catalina, San Clemente and the Channel Islands
- Hard-bottom spots off San Diego and the Palos Verdes coast
- Sand-rock edges in 100-250 ft from party boats
Where they live
How to catch them
Dropper-loop bottom fishing
Rig: Two dropper loops with #2-1/0 hooks above a 6-10 oz sinker
Bait/lure: Squid strip — a thumbnail-sized pennant
Key tip: Keep baits fresh and small; whitefish peck big squid chunks apart without hooking up.
Jigging the bank
Rig: Shrimp-fly rig or small jig worked with short hops on bottom
Bait/lure: Small metal jig or shrimp fly tipped with squid
Key tip: Fish the up-current edge of the rock — the school feeds facing the flow.

On the table
Excellent — the ocean whitefish is a tilefish, and its sweet, firm flesh rivals the best rockfish; watch for bones in the fillet.
