The European Environment Agency has published a report on food systems approaches for the seafood industry in Europe, with the explicit aim of making ‘a first contribution to the collective endeavour of rethinking Europe's food system for sustainability goals’.
The authors used a species distribution model and applied this to the 887 marine fish (which represents 60% of global average annual catch in the 2000s) and invertebrate species in the world oceans under high and low emissions scenarios. The authors find that global maximum catch potential (MCP) is projected to decrease globally by 7.7% between 2010 and 2050, under the business as usual scenario, and the global revenue from this is predicted to decrease by 10.4% compared to 2010. Under the low emissions scenario, MCP is projected to decrease globally by 4.1% and revenue by 7.1%
Researchers from Conservation International have found a small island near Timor-Leste with staggering species richness. Atauro Island, home to about 8,000 people sits in the middle of the so-called Coral Triangle, known for its biodiverse marine environments.
This is the 2016 edition of the FAO’s State of World Fisheries and Aquaculture. The report estimates that fish now provide 6.7% of all protein consumed by humans globally, passing the 20kg per capita and year mark for the first time.
This paper by researchers at the Johns Hopkins Center for a Livable Future (CLF) suggests that as much as 47 percent of the edible U.S. seafood supply is lost each year. The paper shows that the majority of the waste is produced mainly at the consumer stage. The waste issue adds another layer of pressure on fish stocks and the global seafood supply that are already seriously threatened by overfishing, climate change, pollution, habitat destruction and the use of fish for other purposes besides human consumption.
This paper finds that increasing global demand for fish (due to increasing incomes and worldwide population growth) and developments in fishing methods together threaten to further increase pressure on the most popular fish types. It considers improvements in two areas that may decrease this pressure; increasing the production of farmed fish (aquaculture) and improving the effectiveness of fisheries management.
The authors assess how various scenarios of change would affect future wild stock status and simulate the stock development until the year 2048. Through different scenarios they outline ways that the fishery and aquaculture sectors might develop in the coming decades for four popular types of edible fish that are the most important for the world market; sea bass, salmon, cod and tuna.
A study on the impact of climate change on fish stocks by scientists from the UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) has identified ocean hotspots for fish extinction and a link between rising temperatures and fish movement.
The Sustainable Seafood Coalition (SSC) has launched a new 'labelling code', intended to ensure that consumers are sure about what environmental claims on fish and seafood mean. A new 'sourcing code' accompanies the labelling and ensures that the coalition members source their fish and seafood products responsibly.
This article published in Proceedings of the National Academy of Sciences discuss the issue of bycatch – non target animals that are accidentally caught or entangled in fishing gear.
A new joint report by World Bank, FAO and the International Food Policy Research Institute (IFPRI) entitled "Fish to 2030: Prospects for Fisheries and Aquaculture” looks at prospects for fisheries and aquaculture and suggests that aquaculture will provide close to two thirds of global food fish consumption by 2030. It highlights the continuing role of China as a major driver of aquaculture demand, and charts the decline in the relative importance of capture fisheries.
Farmagaddeon describes the effects of livestock intensification (“factory farming”) around the world. It makes the case against industrialised agriculture arguing that it affects not only the welfare of farmed animals but also increasingly our countryside, health and the quality of our food all around the world.
This paper finds that many of stocks in the northeast Atlantic are being fished sustainably today and that, given time, those populations should continue to recover. This is particularly positive news as there has long been widespread criticism that the European Union's Common Fisheries Policy is failing.
A study published in the journal Perspectives on Psychological Science reviews the Database on Raising Intelligence to find interventions that increased children’s intelligence. One such intervention involved supplementing infants with long-chain polyunsaturated fatty acids, and the study concludes that this does indeed have a positive impact on children’s IQ.
This interesting blog on the Planet Earth Online website reports on a study from the University of Salford which conducted blind tastings for a range of fish species. Only 15% of British tasters were able to identify cod – even though this is apparently our favourite fish, and we are generally very reluctant to try anything else.
