The common carp Cyprinus carpio introduced in two drainages in eastern Australia are largely descended from European common carp, and in a third drainage they descend largely from East Asian common carp. The partial genetic differentiation among the species in those drainages is consistent with their origins.

Common carp Cyprinus carpio were introduced into Australia on several occasions and are now the dominant fish in the Murray‐Darling Basin (MDB), the continent's largest river system. In this study, variability at 14 microsatellite loci was examined in C. carpio ( n = 1037) from 34 sites throughout the major rivers in the MDB, from 3 cultured populations, from Prospect Reservoir in the Sydney Basin and from Lake Sorrell in Tasm...

The social and economic assessments conducted for the Interior Columbia Basin Ecosystem Management Project characterized social and economic conditions and trends. The basin has a robust economy that is growing, diversifying, and reducing the importance of traditional resource industries. Even so, there remain many places that are not sharing in this prosperity or easily adapting to the changes to traditional rural lifestyles...
