These fish reefs were characterized by their simple structure, consisting only of ropes attached to plastic frames. We tested the hypothesis that “the attachment of bivalves to the ropes creates habitats for gobies” in on-side aquarium experiments. We found that (1) the attachment and growth of bivalves on the ropes created rough surfaces and shadows within the fish reef, attracting juvenile Dusky Triple-tooth Gobies Tridentiger obscrus, and (2) the juvenile gobies entered and settled in the internal spaces of the fish reefs. The gobies utilized the rough outer surfaves of the fish reefs, even when the sessile bivalves entirely covered the fish reefs. Furthermore, as the bivalves were detached, the spaces within the fish reef for the gobies to enter were restored.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会","subitem_publisher_language":"ja"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"©
