Bolivian Amazon lowland fish metacommunity data

Latest version published by BioFresh on Sep 8, 2017 BioFresh

This dataset represents data from the paper Yukoni, T. and Torres L. V. (2016) Fish metacommunity dynamics in the patchy heterogeneous habitats of varzea lakes, turbid river channels and transparent clear and black water bodies in the Amazonian Lowlands of Bolivia. Environmental Biology of Fishes.

This study documents the spatial dynamic of fish metacommunity based on the date sets of 65 sites, covering two geographic patches of transparent water valleys; Manuripi and Itenez Rivers, separated by turbid water valleys originate in the Andes and the Savanna.

Sampling Methods

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 or were placed in calm areas of 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).

Study Extent sample specification: quantitative (abundance data) replicate samples: no

Method step description:

  1. commonly used series of methods steps regarding fish (e.g. sampling, identification, data management)
