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.

Fishery Interaction Between the Tuna Lonline and Other Pelagic Fisheries in Hawaii
Abstract: The Hawaii pelagic surface fisheries and more recently the longline fisheries have grown dramatically. As a result, competition between fisheries on the fishing grounds and in the marketplace has also increased. Physical conflicts between vessels and claims of decreased fishing success by surface (troll and handline) fishermen led to the enactment of Federal regulations limiting the number of domestic longline vessels and the areas in which they can operate. The scientific evidence of biological or economic fishery interaction between longline and small-vessel fishermen is limited but suggests that intense longline fishing near the Hawaiian Islands has the potential to affect catch rates in other Hawaii fisheries. Better data collection and more research are needed to document fishery interaction and to improve fishery management.

Additionally, efforts in 1991 included retagging seals, tagging unknown-age seals, weighing and measuring immature seals, and bleach-marking seals for ID purposes. Also, interatoll movement, survival, injuries, and entanglement of seals were monitored, seal scats and spews were collected, turtles were tagged, and previously tagged turtles were resighted.
