Abstract
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.

Summary
Among eleven Fisheries Management Area (FMA), at least nine are touted to be the migration areas and potential fishing ground for tunas [3,4,5,6,7,8]. Two-third of the tuna catch in Indonesian EEZ (Economic Exclusive Zone) is contributed from archipelagic waters, especially from FMA-713, FMA714, and FMA-715 [1]. The existence of upwelling phenomena causes this region to be rich in potential fish resources, including tuna and skipjack [13]. It acted as a nursery ground and spawning area for tunas and other large pelagic fishes [14]
