4.4 Reef Fishes Condition

From the results of field observations showed that the highest numbers of individuals at site no. 2 1 578 individuals while the smallest amount in site no. 8 977 individuals. Many of reef fishes use coral reefs as a place of refuge, such as avoiding predators or strong currents Steele 1999. Besides, the habit patterns of other fish are to use the reef as a place to spawn and care for the juvenile area. For the largest number of species found at site no. 4 107 species and the least at site no. 3 47 species, whereas for fish densities obtained the highest number at site no. 2 6,31 indm2 and smallest at site no. 8 3,91 indm2. Some species of reef fishes depend on coral reefs as the place looking for food and shelter Friedlander and Parrish 1998. Differences food and feeding habits for reef fishes make their shape and has a territory that is able to provide food in accordance with their diet. Individual abundance and species for reef fish in each site can be seen in the following figure: Figure 8 Number of individuals and species of reef fishes. The result of reef fish diversity index, based on field data obtained showed that site no. 2 and 3 have the lowest score of 2,098 and 2,997 moderate diversity while for the other site have a value above 3, this shows that generally the diversity of reef fish on the Pasi Island is high, if seen from the diversity index H. Increases in the abundance and biomass of large exploited predators or space occupiers in reserves may result in the decline of prey or inferior competitors, and thus an overall decline in biodiversity Micheli et al. 2004. Individual abundance of reef fish based on the group can be seen in the following figure: Figure 9 Abundance of reef fish based on group.

4.5 Suitability Analysis for MCA Multiple Uses Zone

Regional Marine Conservation Area must have a zoning plan which is set in a simple way, making it easy to be understood and adhered to by the community. This zoning on one side intended to save the resources, or diversity of coral reefs, and on the other side for the development of marine tourism and fisheries. T o view the support of local government, community leaders and fishermen, then collected information from 87 respondents, the result is obtained 89.66 support the establishment Pasi Island as a Marine Conservation Area MCA.

4.5.1 Core Zone

Core zone of a marine conservation area is expected to be able to maintain biodiversity and preservation of existing resources in the region. Selection of the location of the core zone should be considered with good, not only based on ecological parameters, but also must consider the social parameters, especially the support of the community, so expect the existence of the core zone can be maintained with high public participation. The following table presents the results of conformity assessment for the core zone at the study site:
