From 16 August to 19 September 1971, 177 ringed seals (Phoca hispida), 121 of which were alive, were taken from nets set in Pauline Cove (69°30′N, 139°W), Herschel Island, Yukon Territory. Some live seals were kept in an enclosure for as long as 48 hours. Nets were found to be age selective, animals between 2+ to 5+ years old being underrepresented in the total catch. A large part of the netting mortality is attributable to attaching the lead lines in the corners of net traps and not being able to tend the nets during the night. All captured seals were aged, measured, tagged, and marked with an electric branding iron or hot iron brand. Blood samples were taken. No mortality occurred during captivity and all seals were eventually released.
