WebWe predicted that shoal cohesion would be greater in single- than in mixed-species shoals. We also hypothesized that mixed-species shoals consisting of fish with a shared history … WebThe influence of shoal activity on shoal size preference in the zebrafish is investigated and it is found that test fish generally preferred the larger shoal, however, this preference could …
Activity, boldness and schooling in freshwater fish are affected by ...
Web20 Jun 2014 · Behavioural variations of the shoal were estimated before and after food distribution in one test, and before and after a four hours confinement stress in a second test. Data resulting from simulations indicate that the two indexes are sensitive to the simulated changes in the cohesion or the swimming speed of the group. WebBy combining high-resolution tracking of fish behavior with computational agent-based modeling, we show that shoal cohesion changed in the direction expected by a trade-off between individual vigilance and the use of social cues. In particular, we document a decrease of individual vigilance in the small-harvested line, which was linked to an ... davis county school calendar 21-22
