In the present paper are dealt with the morphology and ecology of the three species, Trachypenaeus curvirostris (STIMPSON), T. longipes (PAULSON), and T. albicomus, based on the specimens sampled from the Kochi and the Mimase Fish Markets during the period from November of 1976 to April of 1979. Of these three species, Trachypenaeus curvirostris is common in Tosa Bay, but T. longipes is a new record to Japanese waters and T. albicomus is a new species. The latter two species are identified as follows: Trachypenaeus albicomus HAYASHI et TORIYAMA: This prawn is known as \"shiragasaru-ebi\" in Japanese by fishermen in having white antennal flagella (\"shiraga\" means white mustache; \"saru\", red; and \"ebi\", prawn). The rostral spines of this prawn (excluding epigastric) is ranging from 6 to 9 in number, and shows mode at 8. Postrostral carina is faded out at the posterior part of mid-carapace. Trachypenaeus longipes (PAULSON): This prawn is newly named herein \"okisaru-ebi\" in Japanese. (\"Oki\" means offshore waters). Postrostral carina is strong, and reaching to the posterior margin of carapace. The rostrum is almost straight, and non-curved in shape. The number of spines (excepting epigastric) is ranging from 8 to 11, and shows mode at 9, irrespective of sex (Table 1). The fifth pereiopod is longer than those in the other two species. The spawning season seems to extend from May to September in Trachypenaeus curvirostris, from June to October in T. albicomus, and from August to November in T. longipes, on the basis of seasonal changes of maturity factor and color of ovary. Trachypenaeus curvirostris and T. albicomus are inhabiting the waters shallower than about 50m in depth, and T. longipes from 40m to 88m in depth in the offshore waters in Tosa Bay. The annual catch of small-sized prawns landed at the Mimase and the Urado Fish Markets was totalled about 141 metric tons in 1975: Trachypenaeus curvirostris shows about 1.7%, T. albicomus about 21.3%, and T. longipes about 5.4% of the total, and the rest is occupied by various species of shrimps and prawns. Judging from monthly change in frequency distributions of body length, it is estimated that Trachypenaeus longipes reaches to 59.3 mm in average in a year and 97.6 mm in two years in female, and on the other hand, 50.1 mm in a year and 72.5 mm in two years in male. The life-spans of the other two species, Trachypenaeus curvirostris and T. albicomus, are presumably one year in rapidly growing group and two years in slowly growing one.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"土佐湾で1976年11月から1979年4月にかけて実施した調査船こたか丸による小型底びき網試験操業による漁獲物並びに御畳瀬魚市場に水揚されたものの中から標本を採集し,サルェビ属3種の外部形態と生態について検討した。得られた結果は次のとおりである。1. サルェビについては今まで各地で採集されているが,今回報告されたシラガサルエビとオキサルエビは,日本周辺での採集記録として,はじめて土佐湾から採集されたものである。2. シラガサルエビ(Trachypenaeus albiconus):第2触角鞭の色が白いことから,通称“シラガェビ”と云われている。額角上縁棘数は6から9で,8棘を有するものが最も多い。額角から後方に続く頭胸甲背面正中線上の隆起は,頭胸甲のほぼ中央より後方で消失している(図1,図版1,B). 3. オキサルエビ Trachypenaeus longipes(PAULSON):額角は 雌雄ともほとんど水平で上方に湾曲していない。額角の上縁には8~11棘があり,9棘の場合が最も多い。第5胸脚長はサルエビやシラガサルエビよりも長い(図3)。4. 分布水深はサルエビが50m以浅,シラガサルエビが40m以浅であるのに対し,オキサルエビでは40mから88mmまでのやや深みに分布している。5. 土佐湾におけるこれら3種の漁獲状況をみると,サルエビは少なく,シラガサルエビが最も多く,次に,オキサルエビが多い。6. 産卵期は,サルェビが5~9月,シラガサルエビが6~10月,オキサルエビが8~11月と推定される。7. サルエビ属3種の成長についてみると,サルエビとシラガサルェビの雌雄別月別体長組成から同一年級の成長過程を追跡することはできなかったが,成長の速いものでは発生後満1年で親エビに成長し,産卵後死滅するが,成長の遅いものは越冬して2歳群として存在するものとがあるようである。オキサルエビの場合,雄は発生後満1歳で体長50.1mm,満2歳で体長72.5mm,雌では発生後満1歳で体長59.3mm,満2歳で97.6mmに達するものと推定される。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei 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":"nnf_k_12_75","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/2010212457","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":"Toriyama, Masahiro","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"通山, 正弘","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"トオリヤマ, マサヒロ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Toriyama","familyNameLang":"en"},{"familyName":"通山","familyNameLang":"ja"},{"familyName":"トオリヤマ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Masahiro","givenNameLang":"en"},{"givenName":"正弘","givenNameLang":"ja"},{"givenName":"マサヒロ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3331","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":"土佐湾におけるサルエビ属３種の形態的特徴とそれらの生態について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"土佐湾におけるサルエビ属３種の形態的特徴とそれらの生態について","subitem_title_language":"ja"},{"subitem_title":"On Some Morphological and Ecological Notes of the Three Species of the Genus Trachypenaeus (Penaeid Prawn) in Tosa Bay","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003318","relation_version_is_last":true,"title":["土佐湾におけるサルエビ属３種の形態的特徴とそれらの生態について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-22T00:53:45.191048+00:00"}
