  • Global landings of wild-caught seafood have plateaued in recent years. Analysing trends in global fisheries catches, Watson et al.find that distance between sourcing and consumption has increased steadily since the 1950s, with ocean productivity unlikely to meet current consumption rates by 2100.

  • Latitudinal differences in the global distribution of pelagic and demersal teleost fish predators can be explained by the relative inflow of energy at the base of each food chain.

  • Due to legislative shortfalls, species of global conservation concern can still be captured in commercial fisheries. Here the authors show that 91 threatened species are reported in catch/landing databases, 13 of which are traded internationally despite their conservation concern.

  • Marine seismic surveys use high-pressure air guns to explore sub-sea petroleum deposits, but little is known about their impact on marine life. Now it is shown that exposure is linked to increased zooplankton mortality at a range >1 km.

  • Bringing together multiple models and databases on nature’s contributions to people, the authors map these contributions globally and determine the critical areas where their magnitude is the highest and where they provide the highest potential human benefit.

  • Fisheries generated a total of 179 million tonnes of CO2-equivalent GHG emissions in 2011 (4% of global food production). Emissions grew by 28% between 1990 and 2011, primarily driven by increased harvests from fuel-intensive crustacean fisheries.

  • The mean temperature of the catch, an index designed to characterize the effect of climate change on global fisheries catch, increased at a rate of 0.19 degrees Celsius per decade between 1970 and 2006, showing that ocean warming has already affected global fisheries.

  • An integrated assessment of global crop, livestock and aquaculture production, and fisheries landings over 53 years shows how shocks created in one food sector can spill over into multiple sectors, and which regions are shock hotspots.

  • In the ocean, biological responses to climate change include altered distribution, phenology and productivity. A modelling study into the integrated effects of these various changes on fish body size suggests that averaged maximum body weight could fall by 14–24% globally by 2050. About half of the decline is accounted for by changes in distribution and abundance, with the remainder being physiological.

  • The health of marine ecosystems is traditionally assessed by measuring the mean trophic level (MTL) of fishery catches. These authors model catch MTL and actual ecosystem MTL, and show that the former is not a good measure of the latter. They then show that MTLs have actually been increasing in recent years, but that fisheries are still at risk of collapse because all trophic levels have been similarly affected.
