Prototype Indicators of Condition for Deep River Fish Assemblages Developed. Electrofishing in Boatable Rivers: Does Sampling Design Affect Bioassessment Metrics

摘要

Data were collected from 60 boatable sites using an electrofishing design that permitted comparisons of the effects of designs and distances on fish assemblage metrics. Sites were classified a priori as Run-of-the-River (ROR) or Restricted Flow (RF). Data representing four different design options (i.e., 1000 and 2000 m for both single and paired banks) were extracted from the dataset and analyzed.
