Cuisine & Edibility
Brook Trout
Delicate, sweet flesh with a nutty, mild flavor; low fat and fine texture. One of the most prized freshwater eating fish in North America — best pan-fried simply in butter with herbs.
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
Brook Trout
The brook trout is actually a char, native to cold, clean streams of eastern North America. Its olive-green body with distinctive worm-like markings (vermiculations) and red spots with blue halos make it one of the most beautiful freshwater fish.
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.
