Kōura or freshwater crayfish (Paranephrops planifrons) are an important traditional food source for Ngāti Tuwharetoa. There is anecdotal evidence that environmental changes  (e.g., introduction of exotic macrophytes i.e. aquatic weeds and fish e.g. catfish) over the last 30 years or so have reduced koura abundance in Lake Taupo. However, the lack of quantitative information on trends in koura abundance makes it difficult for Ngāti Tuwharetoa and government agencies to formulate plans for managing this taonga species.
