Abstract

In June 2005, following extensive community consultation, national legislation was enacted to change the boundaries of zones that regulate fishing and other resource use in Karimunjawa Marine National Park in the Java Sea, Indonesia. The new park boundaries included five management zones ranging from notake areas to open access. An initial increase in fish biomass in 2005 was not sustained and by 2007 there was no significant difference in mean biomass when compared to the initial surveys in 2004. Analysis by trophic groups suggested that the re-zoning was effective in protecting the biomass of many fishes. Indeed, only herbivorous fish biomass declined significantly within the park boundaries between 2004 and 2007; corallivore, omnivore and planktivore biomass increased while invertivore and planktivore biomass remained stable. However, similar patterns were evident outside the park boundaries, suggests other factors may be responsible for these patterns, such as a decline in effort throughout the region, perhaps as a consequences of a reduction in the number of people in the fishery. Some zones were more effective than others at protecting fish biomass. For example, increases in every trophic group, except herbivores, were recorded in the Core Zone and Tourism Zone. In contrast, most groups declined in the Protection Zone, perhaps as a result
