Abstract
SUMMARY Attitudes towards the conservation of South African indigenous freshwater fishes have changed radically. Initially alien sport angling species were the focus of fisheries interest and local fishes were considered worthless. Gradually, in response to the work of collectors, taxonomists and ecologists, including prominent Limnological Society members, our conservation conscience has been aroused. Species diversity, distribution patterns and rarity have been highlighted. The restricted distribution of Barbus redfin minnows in particular has led to controversy over the impact of alien species on indigenous fishes, putting fish conservation action and attitudes under both public and scientific scrutiny.
