Homing and home-site fidelity in rock-dwelling cichlids (Pisces: Teleostei) of Lake Malawi,Africa

Synopsis Existence of home site fidelity and homing ability was established for Pseudotropheus aurora. Territorial males stayed up to 1 1/2 years within the same territories. Females showed long-term fidelity to certain places. Transplantation experiments revealed that P. aurora males home over distances of up to at least 2500 m but would not cross deep water. The territorial males of five other sympartic species returned from 1000 m to their territories. The mechanisms and functions of homing in cichlids are discussed.
