Possible Effects of Sampling Biases on Reproduction Rate Estimates for Dolphins in the Eastern Tropical Pacific (open access)

Possible Effects of Sampling Biases on Reproduction Rate Estimates for Dolphins in the Eastern Tropical Pacific

From introduction: The purpose of this report is to present a sensitivity analysis on the effects that biased sampling of young calves and lactating females would have on the various estimated life history parameters. This sensitivity analysis provides one measure of reliability of the various estimates. Also, where inconsistencies in the estimates can be identified, this analysis provides one means for evaluating which estimates are likely in error.

Censuses and Interatoll Movements of the Hawaiian Monk Seal on Laysan Island, 1985 (open access)

Censuses and Interatoll Movements of the Hawaiian Monk Seal on Laysan Island, 1985

Abstract: Research on the Laysan Island population of the endangered Hawaiian monk seal, Monachus schauinslandi, was conducted from 2 march to 30 November 1985. census totals excluding pups ranged from 76 to 147, an average increase of nearly 20 animals from the 1984 census results. Overall monthly haul-out distribution for all seals showed highest use in the north ecological unit followed by the west unit. Relatively few animals hauled out in the eastern and southern portions of the island. Interatoll movement of nine seals was documented, resulting in a net increase of three animals to the Laysan Island population.

Forces of Change in Hawaii's Aku (Skipjack Tuna) Industry, 1986 : Workshop Summary

From preface: This is a report of a workshop on the Forces of change in Hawaii's aku (skipjack tuna, Katsuwonus pelamis) industry. The workshop was held on April 30 and May 1, 1986 in Honolulu, Hawaii and was coordianted by the Southwest Fisheries Center (SWFC) Honolulu Laboratory, National Marine Fisheries Service, NOAA. The objectives of the workshop were: 1. To review the status and current research on Hawaii's aku fishery, and 2. To introduce and prepare background material for discussion at a joint industry-government planning session to be held at a later date.

Hawaiian Monk Seal Reproduction and Injuries on Lianski Island, 1982 (open access)

Hawaiian Monk Seal Reproduction and Injuries on Lianski Island, 1982

Abstract: data on the Hawaiian monk seal, Monachus schnauinslandi, including pup production, pupping locations, and injuries at Lisianski Island in 1982 are presented. Twenty-eight pups were born, of which 26 survived to weaning. Of the observed births, 75% occurred on the east side of the island. Average nursing period for 14 mother-pup pairs was 37.4 days. One exchange of pups was observed. Ten seals were injured while personnel were present on the island. Four of these injuries were attributable to attacks by adult male seals.

Field Manual for Phocid Necropsies (Specifically Monachus schauinslandi)

From introduction: This necropsy manual is a guide for students and technicians in the examination of dead phocids, specifically the Hawaiian monk seal. With this manual, the person performing the necropsy should be able to conduct a gross examination of a monk seal and collect the necessary tissues for microscopic pathology and toxicological studies. The necropsy instructions are based on the assumption that the seal's carcass is very fresh and time is not a limiting factor.
