Solutions to the many capture fisheries and aquaculture problems include (but not limited) to co-management, ecosystem-based management, marine protected areas and sustainable aquaculture practices (CRC, 2006). Essay one used dataset from 2005 and 2009 surveys, the study stills shows the efficacy of co-management in managing resource conflicts and improve collaboration over fisheries in Indonesia. This finding strengthens the Worldwide Collaborative Research Project on Fisheries Co-management (WCRPFC) phase I finding that co-management is a potential option in managing conflicts between resource users who have the exclusive use rights and those who are excluded (Nielsen et al., 2004). Essay two determined the optimal MPA size using biological data from the Eastern part of Indonesia. The bioeconomic model finds that the optimal MPA size is 37.77 percent of total fishery area to be closed as no-take zone. In this model, the open area of fishery is managed by a social planner who applies traditional management measure called ‘sasi”. It turns out that a combination of “sasi” and 37.77 % of MPA size has the highest cumulative profits compare to “sasi” only or open access. Essay three finds that IMTA technology is potentially able to reduce the cost of salmon aquaculture. Based on laboratory data, the analysis investigates the economic consequences of growing mussels on salmon farm through reducing the number of lice treatments needed. This study finds that indeed growing mussels on salmon farming could impact the economic return positively although the percentage is not very high.
