We investigate how high seas closure will affect the availability of commonly consumed food fish in 46 fish reliant, and/or low income countries. Domestic consumption of straddling fish species (fish that would be affected by high seas closure) occurred in 54% of the assessed countries. The majority (70%) of countries were projected to experience net catch gains following high seas closure. However, countries with projected catch gains and that also consumed the straddling fish species domestically made up only 37% of the assessed countries. In contrast, much fewer countries (25%) were projected to incur net losses from high seas closure, and of these, straddling species were used domestically in less than half (45%) of the countries. Our findings suggest that, given the current consumption patterns of straddling species, high seas closure may only directly benefit the supply of domestically consumed food fish in a small number of fish reliant and/or low income countries. In particular, it may not have a substantial impact on improving domestic fish supply in countries with the greatest need for improved access to affordable fish, as only one third of this group used straddling fish species domestically. Also, food security in countries with projected net catch gains but where straddling fish species are not consumed domestically may still benefit indirectly via economic activities arising from the increased availability of non-domestically consumed straddling fish species following high seas closure. Consequently, this study suggests that high seas closure can potentially improve marine resource sustainability as well as contribute to human well-being in some of the poorest and most fish dependent countries worldwide. However, caution is required because high seas closure may also negatively affect fish availability in countries that are already impoverished and fish insecure. [ABSTRACT FROM AUTHOR]

Abstract: The recent creation of the Tun Mustapha Park (TMP) in the northern waters of Sabah, Malaysia has brought up the need for understanding the coral reef fisheries system in Pulau Banggi, for which there has been no previous documentation. This study draws upon field data collected in June and August 2004 to accomplish two things, namely, to build a profile of the ecological and socio-economic aspects of Pulau Banggi''s reef fisheries, and undertake a preliminary assessment of the status of these fisheries. This research is important because it provides information that will help managers develop policies for the long-term ecological and socio-economic sustainability of Pulau Banggi''s reef fisheries.
