This is a priority action of the National Tuna Management Plan (NTMP) for tropical and neritic tuna. Fisheries operating in the IAW are mainly small scale commercial vessels. A specific harvest strategy framework that appropriate with the fishery characteristics has been developed. This paper describes the process of harvest strategy (HS) development for the tropical tuna in the Indonesia’s archipelagic waters (FMAs 713, 714 and 715). The HS is developed scientific works (including data collection, analysis/modelling and series technical and consultative stakeholder workshops as well as expert consultancies. Four technical workshops and seven stakeholder workshops have been done between 2015 and 2017. An interim HS (consisted of management objective, limit reference point, monitoring, analysis, harvest control rule and management measure) has been determined and agreed. Continues collaboration and commitment from related stakeholders including Government, fishers, fishing association, NGOs by adopting co-mangement and participatory approach in implementing the agreed harvest strategy, through data collection and sustain supports.The time series of catch and effort data, and size data could be used to monitor the fishery, stok status and its performance.In addition, involvement of relevant international tuna experts through expert consultancies are integrated process with the technical and stakeholder workshops. This HS development process is still on-going and can be refined, as HS development is a cycle and an iterative process.

FMAs 713, 714 and 715 are Indonesia archipelagic waters (IAW) which not belongs to the WCPFC convention area, whereas the other two FMAs 716 and 717 that have 12 nm of territorial waters are also located 200 nm ofthe Indonesian Economic Exclusive Zone (IEEZ). The IEEZ is under the WCPFC Convention Area (WCPFC-CA) which is under the management of this commission, unlike the archipelagic waters. The IAW is under the statistical area of the WCPFC, which Indonesia has a sovereignty rights to manage its fishery (Anon, 2017). The IAW, FMAs 713, 714 and 715 have been considered to have a higher contribution to the Indonesian tuna catch relative to the IEEZ, with proportion of around 60% came from the IAW (Anon, 2017, Satria et al., 2014; Satria et al., 2015; Satria et al., 2016; Satria et al., 2017).Fisheries operating in the IAW are mainly small scale commercial vessels using pole and line, purse seine, handline, troll line and gillnet, which highly influencing the livelihood for the small scale fishers. These vessels mostly fish using or nearby fish aggregating devices (FADs), and they targeting tropical tuna, comprised of approximately 65% skipjack (Katsuwonus pelamis - SKJ), followed by 28% yellowfin (Thunnus albacares - YFT) and 6% bigeye tuna (T. obesus - BET) in 2016 (Satria et al., 2017). ___________________ correspondence author: e-mail: fsatria70@gmail.com
