Description:This proceedings was produced and published with funding received by the University of Hawaii Sea Grant College Program from NOAA Office of Sea Grant, Department of Commerce. Additional funding was provided by the National Marine Fisheries Service Honolulu Laboratory, the Division of Aquatic Resources of the Hawaii Department of Land and Natural Resources, and the U.S. Fish and Wildlife Service Pacific Islands Area Office. We now know so much more of substance about the Northwestern Hawaiian Islands and the main Hawaiian Islands that we will no longer let anyone engage in discussion about this area with vague and unspecific generalizations. There is now no area of concern for which there is not significant scientifically based information from which we can start. What do we know? We know the geological development, the interaction of the geological-biological processes of the formation of our islands and how they have grown and are growing and how they are sinking in the ocean. We know there are 14 million seabirds, we know that we have a leeward chain of Hawaiian Islands which have a unique and fragile terrestrial community. We know that monk seals are their own worst enemies when it comes to survival. We know that whole green turtles can be consume by an individual shark. We know a lot about stock assessment. We have a somewhat modified understanding now of the energetics, the predator-prey and toxin relationships. We know that the reef community can produce, under appropriate management, a meaningful, sustainable yield. We know we can have a significant but not major yield of alfonsin, armorhead, and other bottomfish. We know we can have a significant yield of shrimp and pelagic fish and we can have a major yield of squid. We can have a culturally and perhaps economically sustainable yield of precious coral. We know the bounds and the nature of primary and secondary production in the waters of the Hawaiian Archipelago; and we can derive the limit of the total productivity of these waters. And quite surprisingly and quite magnificently, we now have a simplified and linear model of the ecosystem which, when calibrated with our knowledge about the top level of the chain and our primary productivity, gives the ability to fairly safely interpolate in between. And we know that we can employ this model to examine adaptations and to determine what happens as we introduce humans as the top level predator in this ecosystem. We have learned from our studies that while it may be easy to introduce humans into this particular model we know less about the behavior of humans, their energetics, their management, and their capabilities than we would like, but we do know more about the behavior of humans as a result of the tripartite-Sea Grant studies than we did before.
