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.

Stock Assessment of the Main Hawaiian Islands Deep7 Bottomfish Complex Through 2010
From abstract: A stock assessment of the main Hawaiian Islands "Deep7" bottomfish complex was conducted through fishing year 2010, including projections to determine total allowable commercial catches (TACs) and their probabilities of overfishing. This assessment was conducted using re-audited bottomfish catch and effort data from commercial catch reports for the years 1948-2010.

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.

Estimation of Hawaiian Monk Seal Corruption in Relation to Ecosystem Biomass and Overlap with Fisheries in the Main Hawaiian Islands
This report analyzes the possible effects of the rehabilitation of Hawaiian monk seals and how their increase in numbers will affect the ecosystem and our fisheries. The document takes into account conclusions that overestimate potential monk seal impacts, and underestimate potential impacts of human extraction on monk seals.
