Computing in fish schools
A model based on shoaling fish suggests how a group can show decision-making properties beyond those of any one individual.
متن کاملSteering mechanism of fish schools
The steering mechanism of fish schools was analysed by using an analytical model and computer simulation. The analytical model is based on fundamental behavioural rules such as attraction, parallel-orientation, and repulsion. Multiple individuals following the same rules interact with each other and thus realize school movements. The results show that when the school advances, unstable movement...
متن کاملDiel behavior of sardine and anchovy schools in the California Current System
Fish schools containing Pacific sardine Sardinops sagax and northern anchovy Engraulis mordax were observed in 2 regions within the California Current System in 2 years using a combination of moored and shipboard acoustics and net sampling. Schools of sardines and anchovies off the Oregon coast followed typical diel patterns consistent with antipredator behavior, dispersing at nighttime, rapidl...
متن کاملFish schools: an asset to corals.
Schools of juvenile haemulid fish feed in sea grass beds at night. By day they rest over coral heads, where they excrete substantial quantities of ammonium and particulate nitrogen and phosphorus into the nutrient-poor waters. The percentages of these nutrients contributed by the fish were comparable to those from other sources. Coral heads with resident fish schools grew faster than those with...
متن کاملCollective gradient sensing in fish schools
Throughout the animal kingdom, animals frequently benefit from living in groups. Models of collective behaviour show that simple local interactions are sufficient to generate group morphologies found in nature (swarms, flocks and mills). However, individuals also interact with the complex noisy environment in which they live. In this work, we experimentally investigate the group performance in ...
