TLDR
The results show that commonsense reforms to fishery management would dramatically improve overall fish abundance while increasing food security and profits, and that, with appropriate reforms, recovery can happen quickly.Abstract:
Data from 4,713 fisheries worldwide, representing 78% of global reported fish catch, are analyzed to estimate the status, trends, and benefits of alternative approaches to recovering depleted fisheries. For each fishery, we estimate current biological status and forecast the impacts of contrasting management regimes on catch, profit, and biomass of fish in the sea. We estimate unique recovery targets and trajectories for each fishery, calculate the year-by-year effects of alternative recovery approaches, and model how alternative institutional reforms affect recovery outcomes. Current status is highly heterogeneous-the median fishery is in poor health (overfished, with further overfishing occurring), although 32% of fisheries are in good biological, although not necessarily economic, condition. Our business-as-usual scenario projects further divergence and continued collapse for many of the world's fisheries. Applying sound management reforms to global fisheries in our dataset could generate annual increases exceeding 16 million metric tons (MMT) in catch, $53 billion in profit, and 619 MMT in biomass relative to business as usual. We also find that, with appropriate reforms, recovery can happen quickly, with the median fishery taking under 10 y to reach recovery targets. Our results show that commonsense reforms to fishery management would dramatically improve overall fish abundance while increasing food security and profits.read more

The biomass distribution on Earth
TL;DR: The overall biomass composition of the biosphere is assembled, establishing a census of the ≈550 gigatons of carbon (Gt C) of biomass distributed among all of the kingdoms of life and shows that terrestrial biomass is about two orders of magnitude higher than marine biomass and estimate a total of ≈6 Gt C of marine biota, doubling the previous estimated quantity.

TL;DR: Recovery rates across studies suggest that substantial recovery of the abundance, structure and function of marine life could be achieved by 2050 if major pressures, including climate change, are mitigated.

TL;DR: Christopher Golden and colleagues calculate that declining numbers of marine fish will spell more malnutrition in many developing nations and warn of the need to act now to address this threat.

Global food system emissions could preclude achieving the 1.5° and 2°C climate change targets

TL;DR: It is shown that even if fossil fuel emissions were eliminated immediately, emissions from the global food system alone would make it impossible to limit warming to 1.5°C and difficult even to realize the 2°C target.

TL;DR: Current trends in world fisheries are analyzed from a fisheries and conservation perspective, finding that 63% of assessed fish stocks worldwide still require rebuilding, and even lower exploitation rates are needed to reverse the collapse of vulnerable species.

Can catch shares prevent fisheries collapse
TL;DR: A global database of fisheries institutions and catch statistics in 11,135 fisheries from 1950 to 2003 is compiled to test whether catch-share fishery reforms achieve hypothetical benefits and halt, and even reverses, the global trend toward widespread collapse.
