i know why they are illegal in states and in some other countries.
I wanted to buy one of them and I always do research on fish's that I'm buying!!
Importance to Humans
Within areas of its native range, the walking catfish is valued as a food fish and is the focus of both subsistence fishers and commercial farming operations. Owing to its ability to survive extended periods out of water, walking catfish can be sold and traded live with ease, ensuring a fairly fresh food product. Outside of its native range, the walking catfish is a demonstrated pest, with the potential to do severe ecological and economic harm. In response, numerous countries have "blacklisted" the walking catfish, including the United States, which has classified all members of the family Clariidae as injurious wildlife, illegal to possess without a federal permit.
For a clear demonstration of the walking catfish's ability to invade and alter new habitats one need look no further than Florida, USA. The origins of the well-known population of walking catfish thriving in South Florida today date to the early 1960's and are well documented. The initial introduction is believed to be linked either to the importation of adult brood stock by an aquaculture facility in Palm Beach County or to a truck transporting brood fishes between Miami and the town of Parkland, Broward County, Florida. The spread of the walking catfish from this zone of introduction has been nothing short of remarkable. Finding the many hundreds of miles of interconnected canals in south Florida to be a veritable highway for dispersal, this species spread to 20 counties in 10 years, no doubt aided by its ability to traverse short distances over land and potentially enhanced survivorship imparted by parental care of their young.
Besides colonizing a vast area, walking catfish have achieved extraordinary levels of abundance in certain areas of South Florida as well. Analysis by one researcher noted levels of abundance as great as 3,000 pounds of walking catfish per acre.
Since the explosive initial spread of this species in Florida, its dispersal northward has slowed. Studies have shown that the lower lethal temperature for walking catfish is 9.4 - 12.8° C, depending upon the "thermal history" of individual fish. Although such a lower limit would seem to eliminate further northward colonization, concern remains that the species could find refugia in the form of the many warm springs of north central Florida and survive short cold spells through its habit of burrowing into the mud during periods of low temperature.
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.
PredatorsWalking catfish of all ages and size classes fall victim to a wide variety of predators including other fishes, reptiles, birds, and mammals. Wading birds are particularly adept at exploiting walking catfishes "stranded" in shallow drying pools and other evaporating water bodies. Introduced walking catfish in South Florida face at least one other source of mortality. From time to time, walking catfish may be seen migrating en masse from water body to water body, often traversing busy South Florida roads in the process. Such migrations take place most often on rainy nights, as the cool moist conditions reduce the risk of desiccation and abrasion. Nonetheless, scores of individual walking catfish are often killed during these movements by automobile traffic. Sections of roads such as U.S. 41 (Tamiami Trail) can actually become hazardously slick with the crushed bodies of walking catfish.
· ParasitesEnteric septicemia of catfish or "ESC" has been reported for walking catfish. Caused by the bacterium Edwardsiella ictaluri, this disease is of considerable concern to North American commercial catfish operations. 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.
Food Habits Walking catfish are benthic omnivores, industrious in their search for food. A nocturnal species, walking catfish search the bottom with their barbels vigorously sifting through detritus and soft substrates. A true generalist, walking catfish consume a wide variety of prey, including eggs or larvae of other fishes, small fishes, and a number of invertebrate taxa such as annelids, crustaceans, and insects. Given these somewhat indiscriminate feeding habits, it is not unusual to find a fair amount of detritus or plant matter in the gut this species. In densely populated drying pools, walking catfish are particularly indiscriminate in their choice of prey items, often seizing and consuming a wider variety of prey than what may normally be available.
· Reproduction Walking catfish construct nests made of detritus or submerged vegetation. The male guards the adhesive eggs and free-swimming young. 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. A strong correlation between spawning and the wet season appears to be true for the non-native populations of walking catfishes in South Florida as well.
AND THAT IS WHY THEY ARE BANNED/ILLEGAL IN USA!!

Oh, you'd be surprised how many people got their stocks confiscated. It is still illegal no matter how big it is, etc, period.BigJ;2506369; said:
If I were you, I wouldn't suggest such a thing. There could be authorities online who could question your actions even if you think they are kidding or not. Whether the laws were created for little reason or not, we are to follow it. They are still illegal in US however you got them, period. With the legality issue floating around this subject, I think this thread is done.Johny;2508064; said:keep it and dont tell anyone
