Fish may learn to associate food with human presence through recreational hand-feeding, a popular tourist activity. The conditional learning-e. g. when an organism learns by continuous exposure to one stimulus-of different coastal fish species exposed to novel feeding situations was evaluated. The latencies of learning response to the initiation of supplementary feeding were rapid and species-specific. However differences in the learning response between different fishes decreased over time, demonstrating that associating with others might incur costs especially for small-sized species, likely due to increased competition for food. Nevertheless some other fish species did not acquire any specific human oriented behavior, being naturally timid or avoiding humans.
