Numerous small pointed teeth occur in large bands on both the upper and lower jaw of the walking catfish.

(2014). [18], In The Anthropologists' Cookbook (1977), Jessica Kuper noted the importance of the pa beuk to the Lao people and remarked, "In times gone by, this huge fish, which is found only in the Mekong, was fairly plentiful, but in the last few years, the number taken annually has dwindled to forty, thirty or twenty, and perhaps in 1976 even fewer. Dentition Walking catfishes are found in a wide variety of habitats including lakes and rivers but are best known for their ability to thrive where many fishes cannot. Thai fisheries officials stripped the fish of its eggs as part of a breeding programme, intending then to release it, but the fish died in captivity and was sold as food to local villagers. Grey to white in colour and lacking stripes, the Mekong giant catfish is distinguished from other large catfish species in the river by the near-total lack of barbels and the absence of teeth. 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. Geographic Location.

There are well over 20,000 species of fish, each with a unique scientific name. The Florida Museum is open! 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. The striped catfish is native to the Mekong River basin & Chao Phraya River basin in Thailand. [1], The Mekong giant catfish is described as a contemporary example of overharvest. Local Name.

In the United States, the history of the non-native population established in southern Florida during the early 1960’s is well documented. [12] A 2018 study suggests that the Mekong stocks could fall up to 40% as the result of dam projects. 51kg. Upper jaw projects well beyond the lower. Scientific names are used to universally identify and name an organism. Food Habits Such migrations take place most often on rainy nights, as the cool moist conditions reduce the risk of desiccation and abrasion. Family. Keeping the sun catfish in an aquarium is easy. The giant of the Mekong . Because of their mobility and tolerance, and their indiscriminate feeding habits, they have been labeled an aggressively invasive species and blacklisted in several countries, including the US. Redtail. The spread of the walking catfish from this zone of introduction has been nothing short of remarkable. Coloration Larval fish are threatened by habitat fragmentation due to construction of dams which are becoming increasingly common.[8]. Grey to white in colour and lacking stripes, the Mekong giant catfish is distinguished from other large catfish species in the river by the near-total lack of barbels and the absence of teeth.

Besides colonizing a vast area, walking catfish have achieved extraordinary levels of abundance in certain areas of South Florida as well. [10] Due to threats, this species no longer inhabits the majority of its original habitat. The walking catfish may be easily distinguished from many of the North American Ictalurid catfishes in that the walking catfish lacks an adipose fin. When people hear the word catfish they tend to think larger freshwater fish which spend the majority of their time sucked onto rocks or feeding on the bottom. Analysis by one researcher noted levels of abundance as great as 3,000 pounds of walking catfish per acre.

Warm, stagnant, often hypoxic waters such as muddy ponds, canals, ditches, swamps and flooded prairies are common habitat for this fish. The fish was described by Gunther in 1864. Learn what else we are doing to keep you safe. 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. 55kg. Due to a lack of agreement among systematic zoologists, questions have arisen concerning the correct scientific name of some of our fish and shellfish. Nonetheless, scores of individual walking catfish are often killed during these movements by automobile traffic. [13], In Thai folklore, this fish is regarded with reverence, and special rituals are followed and offerings are made before fishing it.

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. Enteric septicemia of catfish or “ESC” has been reported for walking catfish. Predators The branching appearance of this organ, reminiscent of a small tree, is the basis for the name “arborescent” organ. In addition to their scientific name, many species have one or more common names. US Toll Free 1-800-262-0370.

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. The spread of the walking catfish from one or perhaps two points of introduction encompassed 20 counties in approximately 10 years; effectively the entire southern peninsula of Florida. [1][17] It is also listed in Appendix I of CITES, banning international trade involving wild-caught specimens.
