Cuisine & Edibility
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.
Sockeye Salmon
Intense, deep-red flesh with a full, robust salmon flavor and high omega-3 content. Excellent grilled, smoked, or canned; its bold flavor stands up to strong seasonings and wood smoke.
Species Overview
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.
Sockeye Salmon
The sockeye salmon is famous for turning bright red during its upstream spawning migration. Its deep-red flesh is the richest in omega-3 fatty acids of all Pacific salmon species, making it the most valuable commercially.
