In\nthis experiment, effects of salinity on food conversion rate are observed in order to reduce the\npollution through excess food materials. At the same time, an optimal salinity level within the\nrotifer cultures was estimated based on their food conversion rates and tolerance to higher\nsalinities.\nIn Exp. I, population growth rate and food consumption rate were observed at nine salinity\nlevels within the salinity range of 2 to 40%. The density of marine Chlorella saccharophila used as\nfood for rotifers was maintained within the range of 2×10^<6> to 8×10^<6> cells・ml^<-1>. Culture was\ncontinued for 14 days after rotifers were acclimated to each salinity level. In Exp. II, food\nconsumption rate and percentage of swimming individuals was measured at 0.5, 6, and 25 hours after rotifers were transferred to a higher salinity of 35%. The rotifers used were previously\nacclimated to : 10, 12.5, 15, 20 and 30%. Chlorella density was maintained at about 4×10^<6>\ncells・ml^<-1>.\nIn Exp. I, the highest food conversion rate was obtained at 10%. The conversion rates\nbecame gradually lower as salinity increased and decreased. Sharp decrease in conversion rate\nfrom 56 to 35% was observed between 20 and 25%. In Exp. II, food consumption rates of\nrotifers acclimated to 20 and 30% were higher than 90% of the rotifers acclimated to 35%.\nHowever, those of rotifers at : 10, 12.5, and 15% were less than 50%. As for the percentage of\nswimming individuals, rates higher than 95% were observed at : 15, 20, and 30%. The salinity\nrange between 15 and 20% was estimated as an optimal salinity level. The results of this study\nwere aimed at direct application for the seed production of marine fishes.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"666","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山崎, 繁久","creatorNameLang":"ja"},{"creatorName":"YAMASAKI, Shigehisa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4830","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000050117553","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"平田, 八郎","creatorNameLang":"ja"},{"creatorName":"HIRATA, Hachiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"100768","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"AN00040498_v34-1_p37-43.pdf","filesize":[{"value":"521.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040498_v34-1_p37-43.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/751/files/AN00040498_v34-1_p37-43.pdf"},"version_id":"9f83647e-040c-4375-9010-bd3ce825fc0b"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"シオミズツボワムシの飼育における餌料効率と塩分濃度の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シオミズツボワムシの飼育における餌料効率と塩分濃度の関係","subitem_title_language":"ja"},{"subitem_title":"Effects of Salinity on Food Conversion Rate of Rotifer (Brachionus plicatilis)","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["40","4823"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-08"},"publish_date":"2015-06-08","publish_status":"0","recid":"751","relation_version_is_last":true,"title":["シオミズツボワムシの飼育における餌料効率と塩分濃度の関係"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-30T01:16:05.744091+00:00"}
