Abstract:
The development of Marine Protected Areas (KKP) is one
of the management strategies that is
able to withstand changes in ecosystems due to the impacts of climate change
and anthropogenic pressure, through
the conservation of biodiversity. Complex ecosystem can offset the impact of climate change by the presence
of more resilience organisms to support ecosystem function and role. One of MPA role is provide the recruit supply for surrounding waters through spill over
mechanism. Protected broodsctock in
MPA are expected to produce many and
healthy eggs that disperse into surrounding area. The continuous supply
of recruits from the MPA can maintain fish stocks and preserve the diversity. This study was carried out in
TWP Pieh MPA, located in the west Sumatera region
by collecting primary and secondary data. Primary
data were collected through insitu
sampling and laboratory analysis, secondary data was collected to figure out
the condition of coral reef
ecosystems inside MPA. Comparison of
catches inside and outside the area,
analysis of individual distribution and genetic mixing between inside and
outside MPA and modeling of larval
distribution with hydrodynamic models was carried out to compare the condition inside and outside MPA. The results study
indicate that the TWP area. P. Pieh
has been able to conserve the TWP Pieh area for fish resources and coral reef ecosystems within the protected area,
however, the results of genetic analysis and larval distribution show that there is little possibility of genetic mixing between inside and outside the area, which is caused by
factors of reproductive strategy and hydrodynamics. This shows that the fish population inside MPA is less support the recovery
of fish stocks in the
surrounding waters. To increase the role of the TWP Pieh MPA, some efforts that need to be done are to build conservation
areas around TWP Pieh (satellite MPA). As well
as expanding the core zone, particularly near the border area of MPA, to guarantee continues
supply of larva from protected
broodstock inside MPA to the surrounding waters.
