Research Plan for Marine Turtle Fibropapilloma (open access)

Research Plan for Marine Turtle Fibropapilloma

The following report is the results of a workshop held to determine the cause of fibropapilloma (lobulated tumors), thereby ultimately leading to solutions and effective strategies for containment. The urgent need to solve this problem arises from the unanimous belief among the workshop participants that this disease will continue to affect populations of turtles locally and worldwide, adding further to their survival difficulties. The workshop was held in December of 1990 and the research behind the workshop results from about 10 years of observing the species.

Fishery Interaction Between the Tuna Lonline and Other Pelagic Fisheries in Hawaii (open access)

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.
