All About Air Breathing Catfish
Description: Air Breathing Catfish –
These are elongated fishes with long dorsal and anal fins and four pairs of barbels. An accessory organ (the suprabranchial arborescent organ) associated with the gill cavity allows the fish to “breathe” air. Typical species have stout pectoral spines but lack a dorsal spine. Color is typically gray to brown, but albinos are common in the aquarium industry.
Species: There are 13 recognized genera in the family Clariidae with approximately 100 species. All are prohibited in Florida, except the walking catfish (Clarias batrachus), which is restricted. Range: Generally, Southeast Asia, including Pakistan, eastern India, Sri Lanka (Ceylon), Bangladesh, Myanmar (Burma), Thailand, Malaysia, Singapore, Indonesia, and the Philippines, has been affected, and their native range is no longer distinct. The walking catfish (C. batrachus) is established in South Florida.
Habitat: Typically found in transient waters where other fish do not thrive. Spawning Habitats: They build nests of detritus and vegetative matter, and the male protects both the eggs and young fry. Feeding Habits: Benthic nocturnal omnivores feed on almost any type of protein they can locate on the bottom at night.
Age and Growth: May reach 2 feet in length. Potential Concerns: The entire family Clariidae is prohibited in Florida (except the walking catfish Clarias batrachus, which is already established and hence is restricted). Initial concerns were addressed by their somewhat unique ability to move across moist ground between water bodies and occupy a niche to which native species are not well adapted. They are food fish in their native range, where their robust ability to survive out of water allows them to be kept fresh for the market.
