About Treefish
Treefish are the unmistakable rockfish — bold yellow body with dark vertical bars, pink-tipped spines, and a territorial personality to match. You won't confuse one with anything else in the cooler.
They live in shallow rocky reef habitat — crevices, caves, and boulder piles in 10 to 150 ft. That puts them shallower than most deep-water groundfish boat action, so they're a regular surprise on nearshore trips, private-boat kelp runs, and Channel Islands structure dives at 40 to 80 ft.
Size is modest: a pound to two pounds is typical, with the occasional 3-pounder. They're territorial and hold tightly to structure — you have to bring the bait to them.
How to Catch
Put the bait at the reef, not above it. Treefish won't chase far. A cut squid strip on a dropper loop with a 4- to 8-oz torpedo sinker, dropped to structure and held just off bottom, is the standard. Shrimp fly gangions work the same way — light enough sinker to control depth, tipped with squid.
On private boats over shallow reefs (20 to 80 ft), a small swimbait or grub worked slowly along boulder fields picks off treefish that have set up ambush positions. A 3-inch Gulp mullet on a 1/2-oz jig head, hopped slowly through rocky areas, produces. The oilier your bait, the better — cut sardine outperforms cut squid when fish are holding tight to structure and need extra scent.
Treefish aren't difficult to catch when you're on their habitat. The challenge is getting on the right structure.
Eating Profile
Good table fare. Smaller rockfish, but the flesh is firm, white, and mild — the same profile as other Sebastes. They're not going to fill a cooler by themselves, but a few treefish in a mixed-bag limit eat well. Fillet and skin them like any other rockfish.
Common Mistakes
- Fishing too deep. Treefish aren't at 300 ft. If you're running a full groundfish outfit to 250 ft, you'll be catching vermilion and bocaccio. Treefish are the shallow reef fish — adjust depth accordingly on private trips.
- Moving the bait too fast. Territorial fish in a crevice need the bait presented slowly. Park it near the structure and wait.
- Writing them off as a small fish. On light tackle (20 lb braid, 7 ft spinning), a 2-lb treefish from 40 ft is a proper fight. Match the gear to the fish and they're genuinely fun.
Month-by-Month
- Jan–Mar: Closed in most management areas for boat-based groundfish; some shore/kayak access continues.
- Apr: Opener. Shallow reefs immediately productive.
- May–Aug: Peak season. Kelp reefs active, treefish feeding well.
- Sep–Oct: Excellent — calm seas, fish on structure.
- Nov–Dec: Fishing slows as days shorten; boats still produce on good windows.
