Group foraging by a stream minnow: shoals or aggregations?
Article Abstract:
The group foraging behavior of a North American stream minnow, the rosyside dace, was observed. Results show that dace forage independently of each other and only form groups as a result of attraction to profitable foraging locations. Aggression towards individual dace results in departure of the target from the foraging group. Group size does not affect departure probability when there is low aggression within the group. Group foraging behavior is more evident in autumn and may be a response to perceived predation risk.

Cluster analysis and the identification of aggregations
Article Abstract:
Research is presented concerning the restraints of operationally objective characterization which constrain behavioral studies of wild animals in captive situations. A study of schooling in catfish is discussed.
