Soft, delicate white flesh with a mild, sweet flavor; low fat and best eaten fresh. A Gulf Coast favorite — excellent pan-fried, baked with Cajun spices, or used in fish tacos.
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.
雲紋犬牙石首魚
The spotted seatrout, despite its name, is a member of the drum family, not the trout family. It inhabits grass flats and estuaries along the Atlantic and Gulf coasts. Males produce a distinctive drumming sound to attract females.
