scenarios reef fisheries system to sustainably manage the marine ecosystem and can be done properly, correctly and continuously.
a. Scenario 1.
A reef fisheries resources management in the area of sustainable marine conservation area is the type of management that considers the ecological
functions and economic activities in order to obtain a rational and optimal utilization. Reef ecosystems in the utilization of fishery conservation area should
be seen as a balance in the utilization of biomass and the environment. Based on the simulation results sustainability of reef fisheries in island
conservation area and surrounding Liwutongkidi in the first month to nine months to see significant changes.
Gambar 22. Graph of mortality simulation, recruitment, fish stocks, namber of fishing vessel and total catch
Figure 22 shows a decrease of fish biomass and recruitment along with increased activity of fishing catch. If this scenario occurs, then this condition can
the sustainability of reef fisheries predicted will experience a significant decline in month-to-month period. This will give negative impact on the biomass of fish in

the coral reef. Changes in fish biomass can be measured by the number of ships and capture of business by the number of 147 fishing boats. In the first month
until the ninth month of the amount of fishing effort in line with the decline in fish biomass. The seventh month of fishing effort to increase the biomass decreased
until the ninth month period, after the ninth month in a period of ten months out of the fish biomass. Next Fazli et al. 2009, McManus 1997 biomass of fish in an
attempt to capture the effect caused by the excess catch. Appendix 12.
b. Scenario 2.
The simulation results in the preservation of fish biomass Liwutongkidi, Kadatua and Siompu Island to see the degradation of the biomass of fish there are several
variables that must be considered is the biomass of fish, economic benefits and efforts. As in the coral reef ecosystem bio-economy standard model. Changes in
fish biomass is influenced by three biophysical parameters of recruitment, biomass and amount of fishing catch.
