Abstract

The article presents a study on the use of a modified Environmental Monitoring and Assessment Programme (EMAP) aquatic vertebrates sampling protocol to assess diversity of reach-scale fishes in wadeable stream in New Zealand. The study uses single pass electrofishing method to sample fish abundance in 73 stream reaches with 345 meter length. Result shows that 150 meter stream reaches are feasible to describe fish richness using the method, however detection of fishes beyond 150 meter was rare.
