Cuisine & Edibility
鲯鳅
Firm, slightly sweet flesh with large, moist flakes and low fat. Excellent grilled, blackened Cajun-style, or in tacos; one of the most popular sport fish for the table.
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
鲯鳅
The mahi-mahi, also known as dorado or dolphinfish, is among the most colorful pelagic fish in the ocean. Its iridescent blue, green, and gold body fades rapidly after death. It is a fast-growing species, rarely living beyond five years.
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.
