This project addresses human pressures on large river, their effects on
ecology and indicators that can be used to assess impacts
The invasive fish research programme focuses on investigations into the distribution and abundance of pest fish such as koi carp (Cyprinus carpio), goldfish (Carassius auratus), and brown bullhead catfish (Ameiurus nebulosus). It also includes studies on the ecological effects of pest fish and on methods to improve capture efficiency and biosurveillance. Key equipment in this programme is a highly successful electrofishing boat.
