Kottelat reported that the adrianichthyids he observed were heavily parasitized by copepods; native fisherman say these parasites became a problem when Clarias was introduced into Lake Poso in the early 1980s. Voracious snakeheads have also been introduced into the lake, and may have led to the decline of the endemic fishes. He argues that the duckbilled buntingi may not be extinct, but just no longer abundant enough for fisherman to expend effort and so never observed. Whatever its status, Adrianichthys kruyti is an example of an endemic species important as a fishery declining dramatically following exotic species introductions by humans. ♦
