Cuisine & Edibility
Brown Trout
Firm, flavorful flesh ranging from cream to pink; moderately fatty with a richer taste than rainbow trout. Excellent pan-fried, baked, or smoked; highly regarded as a European table fish.

Species Overview
Brown Trout
The brown trout is native to European rivers and has been introduced worldwide. Renowned for its wariness and intelligence, it is the ultimate quarry for fly fishers. Larger specimens become nocturnal, feeding primarily on smaller 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.
