摘要

Nam Theun 2 is the largest neo-reservoir in Lao PDR that was impounded to produce electricity. The objective of this study was to assess the input of the offshore zone to the total fish production. Hydroacoustics in areas > 5?m deep were sampled during the cold-dry season for 2 consecutive years. Results showed low fish densities (200–300 ind. ha?1), low biomass (?
