And, as GROTK said, no substancial effect may be seen on the total production as Biomass since all of many species there are to coact to cancel any partial elevation as well as depression of it, which may be resulted by any slight change in the biotic and/or abiotic enviroments. However, what composition of organisms the Biomass will have is a different problem, and this might be essensial for fisheries. Then, we can find little significance in monospecific analysis of the fisheries resources and it is needed for us to take into acount the structure of production and possible effects of fishing on it as well as the resultant composition of the community. Some authors, who studied fish culture in ponds and lakes, have reported that a comparatively stable and satisfactory fishery landing can be expected when the community contains 14 -- 25% carnivorous fish while it seems to be a little different in the sea as the present author reported previously. In Fig. I, trophic composition of catches from different regions of Inland-sea and its adjacent area are given, which shows that the pisci-predator composition decreases in the inner regions. This tendency might show that a larger area must be taken for unity to cover the migration range of some species of the inner community, but at the same time, it might be a problem how fisheries in Inland-sea, possibly intensive, has contributed to the present situation. In Inland-sea, in spite of an expectable total catch in weight to the productivity of this sea area, the value per unit weight has been gradually decreased these thirty years (Table 2), showing the composition of organisms is becoming more undesirable for fishery (Table 3). Perhaps it may be natural to suppose that this change has been effected by fishery, but whatever cause it may be, it tells- us without ambiguity that the composition of community is of vital importance to the fisheries management.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"内海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Naikai Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nai_k_0601","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010841436","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00176718","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0497-5022","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hanaoka, Tasuku","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"花岡, 資","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ハナオカ, タスク","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Hanaoka","familyNameLang":"en"},{"familyName":"花岡","familyNameLang":"ja"},{"familyName":"ハナオカ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tasuku","givenNameLang":"en"},{"givenName":"資","givenNameLang":"ja"},{"givenName":"タスク","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3381","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Communityとして見た水産資源に関する一考察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Communityとして見た水産資源に関する一考察","subitem_title_language":"ja"},{"subitem_title":"A consideration on fisheries resources as a community of organisms in the sea","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-17"},"publish_date":"2024-05-17","publish_status":"0","recid":"2005058","relation_version_is_last":true,"title":["Communityとして見た水産資源に関する一考察"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-05-26T07:41:38.975736+00:00"}
