Cuisine & Edibility

Nile Tilapia

Mild, slightly sweet white flesh with low fat and a firm texture; absorbs marinades and spices well. One of the world's most farmed fish; excellent grilled, fried, or baked.

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

Nile Tilapia

The Nile tilapia is the most widely farmed fish species in the world, cultivated in over 120 countries. Originally from Africa, it is a hardy, fast-growing mouth-brooder that thrives in a wide range of environmental conditions.

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.
