Prey detection by the blue-eye, Pseudomugil signifer Kner ( Atherinidae): analysis of field behaviour by controlled laboratory experiments.

Observations in a brackish creek in E Australia indicate that blue-eye includes various kinds of insects in its diet in the proportions encountered, provided that they are below a maximum size dictated by the mouth-gape of the fish. Encounter rates are affected by prey body size and water turbidity, but not by hunger level of the fish. Fish fed on insects at 0.04-0.08 mg s^-1.-from Authors.
