“…An advantage of this custom system is that it can record and analyze up to 1 h of video at 30 fps. This represents notable increases in recording periods and frame rates over previous systems (Partridge 1980;Fuiman and Webb 1988;Rehnberg and Smith 1988;Hartwell et al 1991;Hassan et al 1992;Bumann and Krause 1993;Gallego and Heath 1994;Higgs and Fuiman 1996;Masuda and Tsukamoto 1998;Suzuki et al 2003). The ability to study longer periods of time becomes more relevant when comparing interactions between fish and changes in social structure over time.…”

Group living among fishes has notable biological significance for individual well being and survival. However, group swimming dynamics have been historically difficult to quantify due to the complexity of the different movement patterns. This study describes and evaluates software developed for the analysis of schooling, shoaling, and solitary behaviors in the mummichog, Fundulus heteroclitus. Analysis of simulated data sets indicated accuracy of the software to within 0.06% of known values (i.e., no functional difference in observed versus expected; P = 0.58-0.93 for all parameters tested). Results from an acclimation experiment with groups of mummichog included decreased schooling, shoaling, individual velocity, and number of interactions after 24 h (P £ 0.05). In addition, there was an increase in shoaling nearest-neighbor angle (NNA) and distance (NND) over time (P £ 0.05). No changes in group behaviors were observed during different periods within 1 day (09:00, 12:00, 15:00, and 18:00 h) after 72 h in the arenas (P > 0.05). These results describe decreased social interactions and polarization (degree of unity in movement) over time. This software is applicable to the study of behavioral ecology of fish to discern changes in group dynamic behaviors.Keywords Schooling and shoaling behavior Á Video-based movement analysis Á Fundulus heteroclitus Á Mummichog Á Killifish

“…Conditioning is the most accurate tool available to investigate sensory potentials and thresholds (see, for example, Neumeier [1988] on wavelength discrimination in goldfish). Untrained fish may change their swim paths upon stimulation (Chivers and Smith, 1993;Essler and Kotrschal, in press;Hartwell et al, 1991). In the case of a negative result (no response to stimulation), this approach is, however, inconclusive as the possibility remains that sensing a stimulus does not translate into significant changes of the locomotory output.…”

There are many reasons to investigate fish locomotion. Topics include activity rhythms, energetics, orientation in time and space, responses to a variety of stimuli, including those originating from food, conspecifics or predators, and ontogenetic changes. Habitat selection and orientation along physical gradients are of considerable interest in ecology. Besides movements of individual fish, group behavior (schooling/shoaling) is relevant in a variety of biological and fishery contexts.According to this diversity of goals, the approaches and the complexity of analysis vary. In the simplest case, activity provides a unidimensional measurement of how much an individual moves. More complex, swim path analysis aims at describing the shapes of the trails by considering parameters such as speed, steadiness of swimming, length of the straight trajectories vs. turns (directions and angles), use of area, distance to conspecifics, etc. By including the vertical axis, a two-dimensional (2D) path may be extended to a threedimensional path GD). A variety of methodological approaches have been used to record fish movements, including visual monitoring, arrays of photocells, time-lapse photography, movie-filming, video-taping, and ultrasonic systems. Due to its superior analytical potentials and ease of application, computer-aided video-systems presently prevail in laboratory applications, whereas ultrasonic telemetry and sonar systems dominate field research.An example is presented of a computerized, video-based, 2D-path analysis of minnows (Phoxinus phoxinus) that were chemically stimulated. Nine parameters were considered and the benefits of multivariate as compared to univariate statistics are shown. With a sufficient number of parameters, the former is superior in distinction and allows judgments on behavior of individuals.
