title: [Laterality of the initial stage of escape response in roach (Rutilus rutilus) upon impact of alternating electric current].
abstract: The initial stage of the escape response (C-bend of the body) upon sudden impact of electric current on free-swimming fish was studied in young roach (Rutilus rutilus). More than half of the fish showed distinct behavioral laterality. i.e., a stabile tendency to bend either to the left or to the right, and retained it until the next test conducted 10 days later. The majority of fish bent to the left, but the difference between the proportions of individuals that showed opposite lateralities lacked statistical significance. This response and the type of laterality are stable and simple to record, which makes the C-bend a convenient experimental model for studying behavioral asymmetry in fishes.
