Bolivian Amazon lowland fish metacommunity data

specification of method(s) used for sampling and sorting: At each site, gill nets were deployed for 2 h each in the evening (17:30-19:30) and the morning (5:30-7:30). Gill nets (25 m long by 2.5 m high) extended from the lakeshore to a calm area in the river channel. Fish were sampled using 13 nets of varying mesh sizes: 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90 and 110 mm. CPUE was calculated for each species and site as the total number of individuals captured in all gill nets during 4 h (2 h each in morning and evening).
