The reproductive states of the pen shells were determined based on histological techniques and the index calculated from measuring shell length and visceral weight.  When the gonads were fully developed, pen shells were transferred into an indoor tank.  Seawater temperature in the tank was maintained at 20°C.  From 2014 to 2015, the pen shells were fed, and induced to spawn in July.  In 2016 and 2017, they were fed for 1 month and 2 weeks, respectively, to stimulate early hatching, and were induced to spawn in June.  In 2017, histological observation of gonads in scaly and non-scaly pen shell indicated that the peak spawning period began earlier in non-scaly than in scaly pen shells, when both were reared in the same area.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"採卵に最適な親貝養成法を検討するため，タイラギを垂下飼育し生殖巣の発達過程を組織学的に観察して産卵期を把握した。生殖巣が発達し成熟期を示すようになった個体を給餌飼育して採卵に用いた。2014，2015年は垂下飼育後自然産卵を防ぐため水温を20°Cに設定して給餌飼育して7月に採卵した。2016，2017年は早期採卵を目指し，垂下飼育後それぞれ1ヶ月，2週間の給餌飼育を行い6月に採卵した。2017年に行った有鱗型と無鱗型タイラギの生殖巣の組織観察から，同じ海域で垂下飼育した場合，無鱗型の方が有鱗型より早めに産卵盛期になると考えられた。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57348/0000000173","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan
