Centrally governed enforcement of blast fishing sometimes has limited success, due to resistance of local populations and mistrust of central governments. Bottom up systems based around clearly defined public benefits and education are more beneficial. Effective MPAs have the backing of local leadership and populations due to clearly defined benefits of conservation/ecosystem services. It has also been shown that effective MPAs have local stakeholders that have accurate perceptions of the environmental health of the region. When coastal residents believe that the ecosystem is healthier than indicators such as species diversity, population, and habitat distribution, they may be less likely to support the MPA. Due to this, effective blast fishing community control relies on education campaigns that bring awareness to the relationship between fish stock and fishing rates.
