英虞湾の５定点の真珠養殖垂下層（２m）の付着生物を調査してつぎのことが判明した。\n2) 出現した付着生物は種類と個体数のいづれも湾中央部の St.３と湾口部寄りの St.４に最も多く，湾口部の St.５と湾奥部の St.１ではそれらのいづれも少なく，特に湾奥部寄りの St.２が最も少なかった。\n3) 湾内の付着生物の盛期は夏季から秋季に至る７, ８, ９, 10 の４か月で，湾内の付着生物相は主として座着性多毛類のカサネカンザシ，ウズマキゴカイを中心に春季の海鞘類と苔虫類，夏季のフジツボ類と秋季のフジツボ類，苔虫類，斧足類の増減によってもたらされる。\n4) 湾内での主要付着生物としてカサネカンザシ，ウズマキゴカイ，フサコケムシ，ホソフサコケムシ，チゴケムシ，コブコケムシ，サラサフジツボ，ヨーロッパフジツボ，タテジマフジツボがあげられる。\n5) 重量変化では夏季７, ８, ９月に St.５で著しい増加がみられ，湾口部におけるフジツボ（特にサラサフジツボ）の速やかな成長が指摘される。\n6) 以前の調査と比較して座着性多毛類の優勢種ウズマキゴカイに代わるカサネカンザシの優勢が認められる。また以前の調査にみられなかった種としてヨーロッパフジツボがあげられる。\n7) 各定点の出現種類数および総個体数とアコヤガイの積算増重量との間には正の相関関係が認められる。しかし総個体数と積算増重量の間では特に St.５を除いた場合にのみ相関関係が成立する。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立真珠研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National
