This paper is a report of Hokke spawning grounds, newly found along the coast of Hidaka, and the biological characteristics of the spawners. Mature fish were collected near the coast of Ogifushi, Hidaka. Body lengths were 31.1 - 38.6cm for males and 31.7- 48.8cm for females. Age, determined from the scales, was 3-6 years and older specimens were observed. They partly mature at age 3 and are almost mature at age 4. The spawning season is thought to be from mid-October to late October. Two factors are thought to be important for Hokke Spawning grounds. One is topographical, a place with a strong current and stony bottom, adjacent to the 200 m contour line; another factor is oceanographical, that the area is affected by the Tsushima Warm Waters from fall to winter. The Hidaka spawners have not seemed important for commercial fishery. The large numbers of juveniles that occurred off the coast of Hidaka in the past, were thought to have been related to the stock caught in Oshima and Hiyama in the next year.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1.日高から道東にかけての海域でホッケの産卵場について調査を行なった結果,日高沿岸に小規模な産卵場が存在することが明らかになった。2.日高沿岸の荻伏で採集されたホッケ成魚の体長は,雄は31.1~38.6cm,雌は31.7~48.8cmであり,年齢は3~6才以上と推定された。3.日高沿岸のホッケは3才で一部が成熟し,4才で大部分が成熟すると推定された。4.日高沿岸のホッケの産卵期は10月中旬~10月下旬と推定された。5.ホッケの産卵場の立地条件としては,岩礁地帯で流れが強く,200m等深線が陸に接近しているという地形的条件とともに,秋から冬にかけて対馬暖流系の水塊(変質水)が分布するという海洋条件が重要であると考えられた。6.かつて,1950年前後に日高沿岸で夏期に大量に漁獲されたホッケ幼魚は、翌年の春に渡島および桧山の沿岸で漁獲された群との関連が強かったことが推察された。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北海道区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Hokkaido Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"作成者","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":"hnf_k_48_1","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/2010282412","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00124758","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0513-2541","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":"入江, 隆彦","creatorNameLang":"ja"},{"creatorName":"イリエ, タカヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Irie, Takahiko","creatorNameLang":"en"}],"familyNames":[{"familyName":"入江","familyNameLang":"ja"},{"familyName":"イリエ","familyNameLang":"ja-Kana"},{"familyName":"Irie","familyNameLang":"en"}],"givenNames":[{"givenName":"隆彦","givenNameLang":"ja"},{"givenName":"タカヒコ","givenNameLang":"ja-Kana"},{"givenName":"Takahiko","givenNameLang":"en"}]}]},"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":"日高沿岸のホッケ Pleurogrammus azonus の産卵場について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日高沿岸のホッケ Pleurogrammus azonus の産卵場について","subitem_title_language":"ja"},{"subitem_title":"Spawning Grounds for Greenling Pleurogrammus azonus in Hidaka, off the Pacific Coast of Hokkaido","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716950587014"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-08"},"publish_date":"2024-04-08","publish_status":"0","recid":"2001750","relation_version_is_last":true,"title":["日高沿岸のホッケ Pleurogrammus azonus の産卵場について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-21T00:55:35.987148+00:00"}
