This paper finds that neonicotinoid use in rice paddies surrounding Lake Shinji in Japan was followed by a collapse in the fishery yields of smelt and eel, likely due to neonicotinoids reducing the abundance of zooplankton on which smelt and eels feed. The paper suggests that similar fishery yields decreases in lake across Japan could be linked to neonicotinoid use.
This report from environmental campaign group Greenpeace International finds that abandoned fishing gear (whether discarded intentionally or accidentally) can be a hazard to marine wildlife for many years, partially due to the durability of the plastic used to make ropes, nets and lines.
This interactive feature from the Global Reporting Program, an investigative journalism organisation, uses text, images and video to explore the fishmeal supply chain, including its sources, its uses in aquaculture, overfishing, waste sludge from fishmeal factories and competition between industrial fishmeal producers and small-scale fish processors.
This report by UK food waste campaigning organisation Feedback examines the use of wild fish and land by the Scottish farmed salmon industry. It finds that the industry, which is largely controlled by six companies, already uses the same amount of wild fish that the whole UK population purchases, and that it would need to use two-thirds as much again to meet its growth ambitions.
Following consultation with fishers and marine conservation experts, the UK government has created new Marine Conservation Zones around the English coast, taking the UK’s total protected areas of ocean to over twice the size of England. However, some critics question whether the protected areas are actually beneficial to wildlife.
This working paper from the UK-based policy research organisation International Institute for Environment and Development explores how fishing subsidies could be reformed to promote social equity and better environmental outcomes.
This working paper from the UK-based policy research organisation International Institute for Environment and Development explores the costs and benefits of different scenarios for future governance of high seas fisheries (i.e. those in international waters) under a changing climate.
This report from the US-based campaigning organisation Changing Markets Foundation examines the impacts of catching wild fish to feed to farmed fish in aquaculture operations, i.e. reduction fisheries.
This paper retrospectively models the impacts of ocean warming on the productivity of 235 fish populations around the world representing around one third of reported global catch. It uses a temperature-dependent population model to estimate that the overall maximum sustainable yield of the fish populations dropped by 4.1% between 1930 and 2010.
This paper models the impacts that the Paris Agreement on climate change would have on seafood production. It finds that three quarters of maritime countries would benefit from the Agreement’s implementation.
Aquaculture generally supplements wild fisheries rather than replacing them, according to this paper, which used models based on historical data.
This report, part of the UK Food Research Collaboration’s Food Brexit Briefings series, argues that the UK’s exit from the European Union will not solve the fishing industry’s problems - rather, that international fishing rules, overfishing and the UK’s own policies have contributed to those problems.
These three audio reports from the Wall Street Journal explore the impact of climate change on commercial fisheries, cattle genetically engineered to tolerate higher temperatures, and how advances in artificial intelligence and genetics could help farmers to withstand crop disease and droughts.
The Pacific Coast Federation of Fishermen's Associations has taken legal action against 30 fossil fuel companies, arguing that the crab fishing industry is being harmed by climate change. Algal blooms, made more likely by warming ocean waters, have cut short crab fishing seasons.
This paper assesses the possibility that cephalopods, such as squid, octopus and cuttlefish, could become a more important source of food in the future. In contrast to many fish population, cephalopod populations have been rising over the last few decades, possibly due to warmer ocean temperatures. The paper gives an overviews of the nutrients provided by cephalopods and the ways that they can be used as food. The authors also note that some cephalopods, including the octopus, are intelligent and possibly sentient, raising ethical issues over their use as food.
