Developed by experts including Timothy Park and Lindsay Marshall, this manual provides essential information for the identification and handling of shark and ray species encountered as incidental bycatch in pelagic tuna fisheries. It features detailed external anatomical measurements, systematic identification keys, illustrated species profiles, and regulatory handling guidelines for purse-seine and longline vessels. This resource is designed to enhance data collection accuracy and support sustainable fishing practices by ensuring that bycatch species are correctly identified and safely managed in accordance with regional fishery management requirements. The document emphasizes educational and research utility, providing clear instructions for the professional monitoring of marine biodiversity within commercial fishing environments.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/shark-and-ray-identification-manual-for-observers-and-crew-of-the-western-and-central-pacific-tuna-fisheries/641488/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/shark-and-ray-identification-manual-for-observers-and-crew-of-the-western-and-central-pacific-tuna-fisheries/641488.png","ImageObject",300,407,{"name":92,"@type":93},"noah","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-01","2026-10-23",true,{"@type":102,"interactionType":103,"userInteractionCount":19},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"Who is the target audience for this manual?","Question",{"text":112,"@type":113},"The manual is primarily designed for observers and crew members working in the western and central Pacific tuna fisheries.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What information is provided for shark and ray identification?",{"text":117,"@type":113},"The manual includes detailed external features, physical measurements, identification keys, and comprehensive species illustrations.",{"name":119,"@type":110,"acceptedAnswer":120},"Does the manual include guidance on how to treat sharks and rays caught by mistake?",{"text":121,"@type":113},"Yes, it provides handling guidelines for purse-seiner and longliner crew members to ensure proper management of incidental bycatch.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},641488,1792714293,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":19,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":81,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":39},1099529839121,"https://ap-avatar.wpscdn.com/davatar_994ba38a5ba835b3df7d355c54d3ed8d","Shark and ray identification manual  \nfor observers and crew of the western and central Pacific tuna fisheries  \nby Timothy Park, Lindsay Marshall, Aymeric Desurmont, Boris Colas and Neville Smith  \nThe SPC Shark and ray identification manual for observers and crew of the western and central Pacific  \nAlthough sharks and rays are an incidental bycatch of pelagic tuna fisheries, these fisheries are accredit  \nDownload the complete version:  \n pdf: {pdfsize Manuals/Park 19 Shark and Ray ID Manual.pdf}  \nTable of contents  \nIntroduction  \npdf: {pdfsize Manuals/Parts/Park 19 Shark and Ray ID Manual Chap1 .pdf}   \nMain shark and ray external features and measurements  \npdf: {pdfsize Manuals/Parts/Park 19 Shark and Ray ID Manual Chap2 .pdf}   \nKeys for shark and ray identification  \npdf: {pdfsize Manuals/Parts/Park 19 Shark and Ray ID Manual Chap3 .pdf}   \nSpecies illustrations and details  \npdf: {pdfsize Manuals/Parts/Park 19 Shark and Ray ID Manual Chap4 .pdf}   \nWCPFC shark and ray handling guidelines for purse-seiner and longliner crew  \npdf: {pdfsize Manuals/Parts/Park 19 Shark and Ray ID Manual Chap5 .pdf}   \nIndexes and glossary  \npdf: {pdfsize Manuals/Parts/Park 19 Shark and Ray ID Manual Chap6 .pdf}   \n©All rights for commercial / for profit reproduction or translation, in any form, reserved.
