Native range: Arctic and sub-arctic rivers of Alaska
The Alaska blackfish is an anomaly in chat it is the only freshwater species occurring in Alaska that does not also occur in Canada. In Alaska this arctic species served as a traditional source of food for local populations and their dogs. One attempt to introduce the species into Ontario was unsuccessful which was surprising due to its hardiness in its native range.

The threadfin shad is a small clupeid with wide habitat tolerances within the warm temperate waters of Eastern North America. The species undergoes population explosions in reservoirs which have caused it to be branded a pest. However its small size makes it an ideal forage species and it has been introduced into reservoirs outside its native range in North America, as well as elsewhere, to serve that function.

The Chinese or mitten crab was probably introduced into European inland waters in the ballast water of ships docking at Bremen. It first appeared in the Aller River, West Germany, diffused rapidly through the Rhine and Elbe watersheds and penetrated to other North European countries through canals and river connections. The species is considered a delicacy in its native range but is a pest in Europe where its habit of burrowing into river banks and attacking fish caught in fishing gear causes a nuisance.

The common pike is a popular sporting fish in much of temperate Europe and North America where it is appreciated for its fighting qualities. The pike is stocked into waters within its native range to maintain sport fisheries, although the usefulness of this practice has been questioned (Grimm, 1982). The species has been introduced to a number of countries but with indifferent success.

The aptly named mosquito fish is one of the species with the widest range of introductions. The species has been transported to every continent to. control mosquitos and has thus acquired a near pan-global distribution. Its extreme tolerance of low as well as high temperatures and of low dissolved oxygen conditions has favoured its establishment over. wide range of climatic conditions. The success of this species in controlling mosquitos has been the subject of mud debate (see for example Gerberich and Laird, 1968). The use of biological vector controls waned with the introduction of pesticides, but recent ecological concern as to the effect! of such bio-toxins has led to a renewed interest in biological control.

The kissing gourami is a popular fish for aquaculture in the Southeast Asian region, where its resistance to low dissolved oxygen makes it ideal for rearing in waters of marginal value to most other species. The species has been introduced into islands of the Indo-Pacific outside its original range for this purpose. The kissing gourami is also a popular fish with aquarists and has been widely transported throughout the world as part of the trade in tropical ornamental species. As a result of escapes from aquaria the species has been reported from U.S.A. and Colombia but its successful establishment in other tropical waters is likely.

Heterotis is a tropical species inhabiting lower reaches of rivers and their floodplains. Its auxiliary branchial air breathing organs enable it to survive in deoxygenated waters. The hardiness of this fish together with its great growth rate make it a candidate for aquaculture in Africa and it has been transported to a number of countries for this purpose. On the whole the species has given satisfactory results under culture. Escapees from ponds into the wild have also established populations which form the basis for fisheries.

The silver carp is one of the Chinese group of carps which has been distributed throughout the world for aquaculture. The species is primarily planktonophage and is used widely in polyculture and also alone for the control of algal blooms. Like other Chinese carps silver carp do not normally breed outside their native rivers and stocks are maintained by artificial reproduction or by continual import of fry. Naturally breeding stocks have appeared in the Danube and, although breeding is not confirmed, wild fish have been collected from the Mississippi indicating that self-breeding communities become established outside the native range if conditions are right.
