{"abstract":"We, the U.S. Fish and Wildlife Service (Service), are amending the definition of \"shellfish\" in the Code of Federal Regulations (CFR) by removing the phrase \"having a shell\" and adding specific taxa. This amendment will clarify that squid, cuttlefish, octopus, and other cephalopods are included within the regulatory definition of shellfish. This action is deregulatory in nature, as it reduces regulatory ambiguity, aligns the Service's regulations with current biological understanding and commercial practice, reduces regulatory burden and is within the Service's purview to amend definitions as needed.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF THE INTERIOR","name":"Interior Department","id":253,"url":"https://www.federalregister.gov/agencies/interior-department","json_url":"https://www.federalregister.gov/api/v1/agencies/253","parent_id":null,"slug":"interior-department"},{"raw_name":"Fish and Wildlife Service","name":"Fish and Wildlife Service","id":197,"url":"https://www.federalregister.gov/agencies/fish-and-wildlife-service","json_url":"https://www.federalregister.gov/api/v1/agencies/197","parent_id":253,"slug":"fish-and-wildlife-service"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/06/23/2026-12578.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"10","title":50}],"citation":"91 FR 37332","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective July 23, 2026.","disposition_notes":null,"docket_ids":["Docket No. FWS-HQ-LE-2026-0628","FXLE12200900000-267-FF09L00000"],"dockets":[{"supporting_documents":[{"title":"Proposed Rule 100 Word Summary","document_id":"FWS-HQ-LE-2026-0628-0002"}],"agency_name":"FWS","documents":[{"comment_count":null,"comment_start_date":null,"updated_at":"2026-06-23T10:57:12.210-04:00","comment_url":"https://www.regulations.gov/commenton/FWS-HQ-LE-2026-0628-0072","allow_late_comments":false,"id":"FWS-HQ-LE-2026-0628-0072","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FWS-HQ-LE-2026-0628","title":"Definition of Shellfish; Inclusion of Cephalopods"}],"document_number":"2026-12578","effective_on":"2026-07-23","end_page":37336,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/06/23/2026-12578.xml","html_url":"https://www.federalregister.gov/documents/2026/06/23/2026-12578/definition-of-shellfish-inclusion-of-cephalopods","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-12578?publication_date=2026-06-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-06-23/2026-12578/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":735,"last_updated":"2026-07-28 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-06-23/pdf/2026-12578.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-12578.pdf?1782132317","publication_date":"2026-06-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/06/23/2026-12578.txt","regulation_id_number_info":{"1018-BJ16":null},"regulation_id_numbers":["1018-BJ16"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Proposed Rule 100 Word Summary","document_id":"FWS-HQ-LE-2026-0628-0002"}],"comments_count":0,"agency_id":"FWS","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FWS-HQ-LE-2026-0628","supporting_documents_count":1,"docket_id":"FWS-HQ-LE-2026-0628","document_id":"FWS-HQ-LE-2026-0628-0072","regulation_id_number":"1018-BJ16","title":"Definition of Shellfish; Inclusion of Cephalopods","checked_regulationsdotgov_at":"2026-06-24T17:55:05Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":37332,"subtype":null,"title":"Definition of Shellfish; Inclusion of Cephalopods","toc_doc":"Definition of Shellfish; Inclusion of Cephalopods","toc_subject":null,"topics":["Exports","Fish","Imports","Law enforcement","Plants","Transportation","Wildlife"],"type":"Rule","volume":91}
