Hawaiian Monk Seal and Green Turtle at Pearl and Hermes Reef, 1990 and 1991

摘要

The primary objectives at Pearl and Hermes Reef in 1990 were limited toconducting atoll-wide seal censuses, resighting tagged seals, tagging weaned pups, and surveying and destroying debris capable of entangling seals or turtles. In addition to these objectives, efforts in 1991 included retagging seals with broken or missing tags, tagging unknown-age seals, weighing and measuring immature seals, and bleach-marking seals for identification purposes. Also, interatoll movement, survival, injuries, and entanglements of seals were monitored, seals scats and spews were collected, basking turtles were tagged, and previously tagged turtles were resighted. The report summarizes the data collected during 1990 and 1991.
