Frequency, composition and stability of associations among individual largemouth bass (Micropterus salmoides) at diel, daily and seasonal scales

A whole-lake acoustic telemetry observatory situated in eastern Ontario was used to continuously monitor the three-dimensional position of 20 largemouth bass (Micropterus salmoides) over a 120-h period during the winter and a separate 120-h period during the early spring. These data were used to eva...

Description
Summary:A whole-lake acoustic telemetry observatory situated in eastern Ontario was used to continuously monitor the three-dimensional position of 20 largemouth bass (Micropterus salmoides) over a 120-h period during the winter and a separate 120-h period during the early spring. These data were used to evaluate the frequency and stability of associations among fish to provide an understanding of seasonal aggregations and the sociobiology of largemouth bass. The temporal and spatial proximity of each fish relative to the other 19 individuals was assessed and, based on our definition of spatial/temporal proximity (i.e., two fish having an average hourly position
