Abstract

Four sites in three small tropical streams each weresampled with three successive electrofishings perconstant unit effort, starting at the site with lowestnatural water conductivity. Each second-fourth sitewas sampled at double water conductivity (up to 300µS cm−1 only) by dissolving salt in thewater. Electric fishing efficiency estimated by threeefficiency indexes was not significantly correlatedwith increasing conductivity. The reasons for this result arediscussed.
