Population Monitoring of the Hawaiian Monk Seal, Monachus schauinslandi, and Captive Maintenance Project at Kure Atoll, 1988

Abstract: Data on the Hawaiian monk seal, Monachus schauinslandi, were collected at Kure Atoll from 23 February to 20 October 1988. Beach counts made on 54 atoll-wide censuses averaged 30.0 seals, including pups of the year. Eight pups (five females and three males) were born; seven survived to weaning. Thirteen injuries to 12 seals were documented, and 5 seals became entangled in marine debris. An estimated 1,195 kg of debris were removed from beaches. Thirty-two of 40 seals tagged at Kure Atoll since 1981 were resighted. Five weaned female pups were maintained in a protective enclosure until 20-21 September, and a yearling Kure Atoll seal, which had been rehabilitated in Honolulu, was maintained in the enclosure from 22 March to 12 May.
