Fish Shoal 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 may be said to be shoaling. 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 behavior such as swimming, so as to remain close to the other fish in the group. Shoaling groups can include fish of disparate sizes and can including mixed-species subgroups.
