Climbing Perch
Anabas testudineus
Climbing Perch (Anabas testudineus) is a hardy air-breathing fish of ponds, ditches, floodplains, and rice fields across South and Southeast Asia. It can survive low oxygen and short overland movements in damp conditions, making it a resilient invasive in some regions.
Giant Snakehead
Channa micropeltes
Giant snakehead (Channa micropeltes) is a large predatory freshwater snakehead from Southeast Asia, notorious for rapid growth and aggressive strikes. Juveniles often travel in schools, while adults become solitary ambush hunters in warm, sluggish waters.
African Tigerfish
Hydrocynus vittatus
African tigerfish (Hydrocynus vittatus) is a fast, predatory African characin known for explosive strikes and powerful runs. It inhabits large rivers and floodplain lakes across much of southern and central Africa.
Alabama Bass
Micropterus henshalli
Alabama Bass (Micropterus henshalli) is a black bass native to the Mobile River basin and closely related to spotted bass. It favors clear to moderately turbid streams, reservoirs, and tailwaters with rock, wood, and shoreline cover.
Alligator Gar
Atractosteus spatula
Alligator gar is a large, ancient ray-finned fish of slow rivers, backwaters, oxbows, and floodplain lakes in the Mississippi basin and nearby coastal drainages. It ambushes fish at the surface and can breathe air, allowing it to survive low-oxygen water.
American Gizzard Shad
Dorosoma cepedianum
American Gizzard Shad is a silvery clupeid forage fish common in warm, slow waters across much of eastern and central North America. It feeds by filtering plankton and detritus, and is important prey for bass, catfish, crappie, and other predators.
American Pickerel
Esox americanus
American Pickerel (Esox americanus) is a slender, ambush-predatory esocid found in vegetated fresh waters across eastern North America. It is smaller and more delicately built than northern pike or muskellunge, with a duck-bill snout and chainlike markings.
Amur Carp
Cyprinus rubrofuscus
Amur carp (Cyprinus rubrofuscus) is a cyprinid carp native to East Asia and widely introduced beyond its original range. It inhabits warm, slow waters and is an adaptable bottom-feeder that can grow large in ponds, lakes, and lowland rivers.
Amur Goby
Rhinogobius similis
Amur goby (Rhinogobius similis) is a small benthic goby associated with cool, clear running water. It is reported from freshwater streams and rivers in East Asia, but available public records can be scattered and some identifications in occurrence data may be uncertain.
Arapaima
Arapaima gigas
Arapaima gigas is one of the world’s largest freshwater fish, native to the Amazon Basin. It breathes air and often rolls or gulps at the surface, making it easy to notice but very challenging to land.
Arctic Char
Salvelinus alpinus
Arctic Char is a cold-water salmonid of Arctic and subarctic lakes, rivers, and coastal waters. It often shows striking seasonal color shifts and can be an important local food and sport fish where it occurs.
Asp
Leuciscus aspius
The asp is a fast, predatory cyprinid of large European rivers and connected lakes. It hunts small fish in open water and is prized by lure anglers, though it can be selective and wary.
