On a global scale, fisheries harvest an estimated 96 million tonnes of fish biomass annually, making them one of the most important drivers of marine ecosystem biodiversity. Yet little is known about the interactions between fisheries and the dynamics of complex food webs in which the harvested species are embedded. We have developed a synthetic model that combines resource economics with complex food webs to examine the direct effects of fishing on exploited species and the indirect impact on other species in the same community. Our model analyses show that the sensitivity of the targeted species increases with its trophic level and decreases with its local interaction complexity (i.e. its number of interactions with prey, predators, and competitors). In addition, we also document a strikingly positive effect of community species richness on the resilience of the harvested species to this disturbance. The indirect effects on other species show specific patterns of spreading across trophic modules that differ systematically from how other disturbances spread across ecological networks. While these results call for further research on how human resource exploitation in general and fishery in particular affect ecological dynamics and biodiversity in naturally complex systems, they also allow for some cautious conclusions. Taken together, our results suggest that the sustainability concerning fishery yield and ecosystem integrity can be maximised by focusing the harvest on low trophic level species with a high local interaction complexity in high biodiversity ecosystems. In this sense, our complex network approach offers a promising avenue for integrating the necessities of generating economic revenue with the protection of natural biodiversity.

“…When initially established in 1999, MMAF used mostly top-down approaches to fisheries management [59], but recent attempts aim to regulate small-scale fisheries through empowerment or recognition of traditional management systems [60]. This effort has had mixed success because of low compliance and commitment from those involved in fisheries management [61,62]. It is difficult for community-based protected areas in Indonesia to be formally recognised as MPAs even if IUCN definitions are met [53], as is the case with locally managed marine areas (LMMAs) [25].…”

“…Over the pandemic, fishers could not rely on savings, loans, or other forms of employment to improve their livelihoods, given that most are small-scale and informal. In Indonesia, smallscale fisheries produce more than 80 percent of the country's fish catch, thereby playing an integral part in sustaining the country's food security and employment (Ayunda et al 2018). About 90-95 percent of Indonesian fishers use vessels that are under 10 gross tons (GT) (CEA 2018).…”

Climate crisis and unsustainable activities in Indonesia’s marine and fisheries sector have led the ocean into troubled waters. The country must strengthen their commitments to ensure ocean resources are managed sustainably and equitably. This report aggregates the best available data and provides in-depth analysis on marine and fisheries issues to encourage evidence-based approaches in decision-making processes.
