This study focuses on (sub-)adult razor clams (Solen gordonis), with shell lengths ≥25 mm, in Sasebo Bay and Omura Bay, northwestern Kyushu, Japan. They are commercially harvested, but little is known about their spatial distribution pattern. The objective was to estimate the spatial distribution and configuration of clam beds existing within an area of ca. 12 km2. For this, clam and sediment sampling by scuba-equipped divers, acoustic bathymetric surveys using a recreational-grade fish finder (single-beam acoustic) system, and presence–absence modelling using generalized linear models were performed. For the collected clams, catch per unit effort (CPUE; number of clams collected/h) was calculated and used as a proxy for clam individual density. The results showed that the presence–absence variation in the spatial distribution of (sub-)adult clams was associated with the bottom sediment type. (Sub-)adult clams occurred frequently in the sediments with higher gravel (particles with diameters ≥2 mm, mainly shell fragments) and lower mud (diameters"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420001326233231104","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"50758844"},{"@type":"NRID","@value":"1000050758844"},{"@type":"NRID","@value":"9000412112036"},{"@type":"NRID","@value":"9000411818407"},{"@type":"NRID","@value":"9000411803536"},{"@type":"NRID","@value":"9000403552397"},{"@type":"NRID","@value":"9000411807041"},{"@type":"NRID","@value":"9000411821525"},{"@type":"NRID","@value":"9000411795158"},{"@type":"NRID","@value":"9000411818603"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/stakeuchi"}],"foaf:name":[{"@value":"Seiji Takeuchi"}]},{"@id":"https://cir.nii.ac.jp/crid/1380849942213951874","@type":"Researcher","foaf:name":[{"@value":"Takeshi Takamasu"}]},{"@id":"https://cir.nii.ac.jp/crid/1380849942213951875","@type":"Researcher","foaf:name":[{"@value":"Saki Nagae"}]},{"@id":"https://cir.nii.ac.jp/crid/1380849942213951872","@type":"Researcher","foaf:name":[{"@value":"Akio Tamaki"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"13851101"}],"prism:publicationName":[{"@value":"Journal of Sea Research"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2019-11","prism:volume":"153","prism:startingPage":"101794"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S1385110118301977?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S1385110118301977?httpAccept=text/plain"}],"createdAt":"2019-09-07","modifiedAt":"2025-10-24","project":[{"@id":"https://cir.nii.ac.jp/crid/1040000781972565760","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"17K15303"},{"@type":"JGN","@value":"JP17K15303"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17K15303/"}],"notation":[{"@language":"ja","@value":"アサリ稚貝生残に与える投石・覆砂の潜在効果の解明：漁場管理技術の躍進に向けて"},{"@language":"en","@value":"Evaluation of the effect of substrate addition on the survival of Ruditapes philippinarum juveniles from novel perspectives"}]}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004239149438464","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Reproductive Cycle of the Razor Clam <i>Solen gordonis</i> in Sasebo Bay, Kyushu, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011143684952448","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"The effect of scallop dredging on Irish Sea benthos: experiments using a closed area"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011143705026176","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Benefits of closed area protection for a population of scallops"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011144961250816","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"pROC: an open-source package for R and S+ to analyze and compare ROC curves"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011145415107200","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Predictive mapping of abalone fishing grounds using remotely-sensed LiDAR and commercial catch data"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011145579590528","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Fine-scale spatial structure of the exploited infaunal bivalve Cerastoderma edule on the French Atlantic coast"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011145602127616","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"The effects of marine protected areas on the population dynamics of a South African limpet, Cymbula oculus, relative to the influence of wave action"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011145716435968","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Mapping seabed biotopes at Hastings Shingle Bank, eastern English Channel.
