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.

Lean, dense flesh with a clean, meaty flavor; prized for sashimi and poke. Excellent seared rare, grilled as steaks, or served raw; one of the most commercially valued tunas.

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.

Yellowfin Tuna

The yellowfin tuna is a pelagic predator found in tropical and subtropical oceans worldwide. Capable of speeds exceeding 75 km/h, it is prized both as a sport fish and for its high-quality sashimi-grade flesh.
