Title: Individual variation in the swimming performance of fishes: An overlooked source of variation in toxicity studies

Abstract

A commonly used indicator of sublethal stress in fish is impaired swimming performance. Analysis of performance data usually employs a simple comparison, in which the mean of a stressed group of fish is compared to that of a control group. Although such a comparison is satisfactory in many cases, a comparison emphasizing individual variation in performance can yield valuable information unattainable by a means comparison. In this experiment, the authors determined critical swimming speeds of subadult male fathead minnows before and after exposure to contaminated sediments from Devil`s Swamp, Louisiana, USA. The data were then analyzed using a means comparison and an individual approach to illustrate the differences in explanatory power between the two approaches.
