Hepatic Steatosis in Cage-Reared Young Cobia, Rachycentron canadum (Linnaeus, 1766), in Brazil

This article discusses the pathophysiology of hepatic steatosis in cage-reared cobias from two fish farms with low growth rate record and predisposition to opportunistic diseases. We performed necropsies of cobias with a history of slow growth, high mortality, lethargy, fin ulceration, skin depigmentation, physical deformities, and certain external parasites. Macroscopically, liver volume was increased with pale, softened and friable consistency.
