loosen Explanation: loosen their close formation? An aggregation of fish is the general term for any collection of fish that have gathered together in some locality. Fish aggregations can be structured or unstructured. An unstructured aggregation might be a group of mixed species and sizes that have gathered randomly near some local resource, such as food or nesting sites. If, in addition, the aggregation comes together in an interactive, social way, they are said to be shoaling.[1] Although shoaling fish can relate to each other in a loose way, with each fish swimming and foraging somewhat independently, they are nonetheless aware of the other members of the group as shown by the way they adjust behaviour such as swimming, so as to remains close to the other fish in the group. Shoaling groups can include fish of disparate sizes and can including mixed-species subgroups. If, as a further addition, the shoal becomes more tightly organised, with the fish synchronising their swimming so they all move at the same speed and in the same direction, then the fish are said to be schooling.[1][3] Schooling fish are usually of the same species and the same age/size. Fish schools move with the individual members precisely spaced from each other. The schools undertake complicated manoeuvres, as though the schools have minds of their own.[4] Reference: http://en.wikipedia.org/wiki/Shoaling_and_schooling |

to distance/less density Explanation: Zwei recht freie Übersetzungen ... animal will seek *to distance* itself from its neighbors in order to avoid a collision. http://en.wikipedia.org/wiki/Swarm oder http://icesjms.oxfordjournals.org/cgi/content/full/61/7/1214 In the model, the orientation and velocity of individuals were defined by the probability density function of a normal distribution and Gamma distributions, respectively. Simulations using the model showed that attraction to neighbours and parallel orientation behaviour are important factors in the organization of a fish school. -------------------------------------------------- Note added at 1 day7 hrs (2010-05-29 14:23:07 GMT) -------------------------------------------------- Zweiters passt besser zum mathematischen Modell.... |
