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.

Firm, white flesh with a mild, sweet flavor and moderate fat; smaller fish (under 27 inches) are the best table size. Famous as 'blackened redfish' — a Louisiana Cajun culinary classic.
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.
美国红鱼
The red drum, or redfish, is an iconic inshore game fish of the Atlantic and Gulf coasts. Identified by the distinctive black spot at the base of its tail, it feeds by tipping head-down in shallow water, exposing its copper-colored tail.
