Biodiversity conservation in SIMCA is highly dependent on the success of enforcing fishing restrictions at the conservation area. The ban against any illegal fishing activities in SIMCA prevents the destruction of the reefs which house various types of fishes, and allows population of fishes within the conservation area to thrive in abundance.
A project funded by United States Agency for International Development’s Coral Triangle Support Partnership (CTSP) was completed in 2012. In the studies of the project, it is found that the total fish biomass and species richness of three fish categories (groupers, snappers and fusiliers) are all higher at reefs that are located within the conservation area, followed by the reefs close to the border and reefs outside SIMCA borders.
From the surveys on giant clam, it has been noted that there are seven species of giant clams that are
