Yellowtail
Seriola dorsalis
A powerful eastern Pacific jack that shifts between nearshore structure and offshore water. Read the yellow tail, the clean dark-over-light body, and the day-feeding pattern before choosing a plan.
Calico Bass
Paralabrax clathratus
Southern California's structure-oriented kelp bass. Learn the white checkerboard blotches, the equal central dorsal spines, and the difference between bass and rockfish before making a keep-or-release decision.
Pacific Bluefin Tuna
Thunnus orientalis
A large, highly migratory open-ocean predator. The short pectoral fin, dark back, silver-spotted belly, and yellow finlets separate it from the other tunas encountered off Southern California.
Honest beta coverage
Verified photography is intentionally held until image rights and attribution are recorded. Original anatomy plates provide the first visual identification layer without borrowing protected artwork.
