The East China Sea (ECS) Large Marine Ecosystem (LME) is a globally significant fishing ground, but the absence of cooperative regional management impedes the future sustainability of ECS fisheries. To navigate around nationally focused perspectives, we provide an up to date synthesis about the socio-economic importance and status of ECS fisheries at the ecosystem level, which is currently lacking in the literature. Our review indicates that ECS LME fisheries contribute around 6 million t in catch and USD 13 billion in landed value annually, and employ up to an estimated 1.4 million, the majority of who are small-scale fishers. However, the fisheries benefits are threatened by intense fishing pressure and rapid economic development which exacerbates the effects of overfishing. The future of ECS fisheries also faces climate uncertainties, which has already been associated with shifts in species distribution and spatial distribution of fishing effort. At the LME level, political disputes that inhibit crucial multilateral fisheries management threaten the future sustainability of ECS fish stocks, and also weaken the effects of national management measures which have largely failed to address fisheries overcapacity and coastal marine degradation. Continuing on a path focussed on national interests without considering LME wide dynamics risks jeopardising the significant fisheries socio-economic and ecological benefits that accrue to all LME countries. Thus, our review emphasises the urgency for multilateral ECS fisheries management to enhance ecosystem resilience so that fisheries resources can continue to support the region's human, social, and economic well-being into the future.
