| Research Abstract |
To evaluate the functions and importance of mangroves as a fish habitat, effects of structural complexity of mangrove roots on the distribution patterns and predation mortality of fishes, and the relationship between prey abundance and fish growth were examined through field experiments at Iriomote Island, Ryukyu Islands, Japan. The results of the experiments suggest that complex root structures are of importance in determining fish distribution patterns due to their functions as shelter and/or feeding areas.
