Fortunately, most such operations are maintained outside the introduced range of the walking catfish, greatly reducing the possibility of wild walking catfishes infecting the farmed fishes, at least in North America.  Trends in water use, energy production, consumption and associated environmental degradation are projected to continue rising in southeast Asia. Heavy-bodied with a wide head and high spot forward of center near the head called the dorsal hump. An extension of the apparatus that supports the fish’s gill filaments, this structure facilitates the uptake of atmospheric oxygen by providing support for a number of gill filaments that would otherwise collapse in the absence of the buoyancy of water.

Overfishing, damming, destruction of spawning, and breeding grounds and siltation have taken a toll on the species' habitat. Sections of roads such as U.S. 41 (Tamiami Trail) can actually become hazardously slick with the crushed bodies of walking catfish.Parasites Palm Tree Lagoon Largest Fish. Given the source of the South Florida population it is ironic that one of the most clearly demonstrated negative effects of walking catfish in the region is their propensity to invade commercial aquaculture facilities, often consuming vast numbers of the stocks of fishes therein. With so many species in so many places, it is inevitable that many common names are applied to more than one species. In the native range of the walking catfish, spawning is coincident with the onset of the rainy season during which the species may construct nests in the flooded environs. From 2000 to 2003, about 10,000 captive-bred specimens were released by the Thai authorities.
