Cuisine & Edibility

Saumon royal

The largest Pacific salmon; exceptionally rich, fatty flesh with deep orange-red color and a full, buttery flavor. Superb grilled, smoked, or cured; the benchmark of Pacific salmon quality.

Plecostomus

Not consumed — ornamental algae-eating catfish kept as a natural tank cleaner; widely popular in freshwater aquariums for its armored body and bottom-dwelling habits.

Species Overview

Saumon royal

The chinook salmon, also known as king salmon, is the largest of the Pacific salmon species. It undertakes epic migrations from the ocean to its natal river to spawn once before dying, providing nutrients to the entire watershed ecosystem.

Plecostomus

The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
