“…Most of the data available for determining the stock status of the fisheries in FMA-714 were from port monitoring programs [15,18,28]. However, such data requires a lot of investment, especially in human resources (enumerator), securing fund for their wage bills and other expenses.…”

“…This drives the necessity for conducting harvest strategy as the foundation for sustainability. Hoshino et al [15] started a pilot project in 2020 for assessing yellowfin and skipjack tuna. Although an interim harvest strategy has been adopted, but the key uncertainties i.e., abundance indices and effective sample size still need to be improved in order to get a more robust analysis.…”

Tuna and tuna-like fisheries play a vital role in Indonesian livelihood, especially in the archipelagic waters. However, despite the importance, the concern in general data collection activities for tuna, i.e., limited, with incomplete scientific knowledge and insufficient data has hampered the assessment. The purpose of this study was to analyse on how fisheries-dependent data system could transform the data quality. For this purpose, the analysis was conducted based on e-logbook data from January to December 2020. The result showed that some robust fisheries indicators (catch, effort, fleet and species composition) could be produced from this particular dataset. In addition, e-logbook has the best attribute for improving the data quality, especially for small-scale tuna fisheries in FMA-714. Low cost and vast spatial and temporal coverage are the main characteristics on why the program should be expanded and monitored carefully in the future.

“…It does not have TACs, which are foundational for ITQs. The Ministry of Marine Affairs and Fisheries continues to work towards strengthening data collection and stock assessment, aiming to develop harvest strategies for key fisheries such as tuna (Hoshino et al, 2020). In line with fisheries management internationally, Indonesia is also moving towards ecosystem-based management, with comanagement between government and industry (Muawanah et al, 2018).…”

This chapter examines the role that governance plays in shaping fishing livelihoods. This includes formal government regulation as well as other factors that shape fishing, such as markets, buyer requirements and social norms. Institutional arrangements serve as a key component of fishing livelihoods, by prescribing the conditions under which fishing livelihoods operate. In this chapter we sketch out some of the trends in fisheries governance across parts of the Asia-Pacific, before discussing examples in Australia and Indonesia.

“…These ‘data‐limited’ indicators may be as simple as, progressive dynamic adjustments of catch or effort limits, for example, until a particular size‐based indicator target is reached (e.g. Prince & Hordyk, 2019) or according to relative abundance index levels (Carruthers et al, 2016; Geromont & Butterworth, 2015; Hoshino et al, 2020; Jardim et al, 2015), or trigger action based on a system of interlinked indicators with respective thresholds (Dowling et al, 2015; Harford et al, 2021).…”

Fisheries managers are in need of quantitative tools to inform decisions regarding selection of robust management practices, prioritising research gaps and stocks to focus on, particularly where there are limited resources or data. To support these decisions, the use of Management Strategy Evaluation (MSE), that is, closed loop simulationtesting of management procedures, is widely regarded as best practice. However, applying MSE is time-and computationally intensive, and requires highly skilled expertise and processes for stakeholder input and peer review. For data-and capacitylimited fisheries, MSE may be particularly challenging to implement. Yet, these are the contexts where it is most critical to test assumptions, evaluate the implications of all sources of uncertainty and identify the most informative data sources. To facilitate wider use of MSE, the Method Evaluation and Risk Assessment (MERA) framework was developed as an accessible online interface, with quick processing time, focused on generic data-limited management procedures, but allowing progression to tailored and more data-rich methods. The framework links a quantitative questionnaire and data input standard to a flexible operating model with optional customisation via command line access to the back-end open-source R libraries. Here, we illustrate a case study application of MERA for the bocinegro (Pagrus pagrus, Sparidae) fishery in the Gulf of Cadiz, where in conjunction with fishery stakeholders, a custom management procedure was developed and tested and key research gaps and data collection priorities were identified. We discuss implications for wider use of MSE in various contexts, including eco-certification and fishery improvement projects.
