global momentum to secure healthy and productive oceans, a momentum whose pace will receive further impetus at the second United Nations Ocean Conference. Navigating this crossroads demands a vision that outlines how the sector can respond to the complex and rapidly changing challenges facing society.
Illegal, unreported and unregulated fishing remains one of the greatest threats to marine ecosystems, undermining efforts to manage fisheries sustainably and to conserve marine biodiversity . Fisheries resources are frequently poached, often leading to the collapse of local fisheries, with fisheries in developing countries proving particularly vulnerable. Products derived from IUU fishing can find their way into overseas trade markets, thus throttling the local food supply.
Moreover, improved utilization of fisheries and aquaculture production reduces loss and waste, and can help reduce the pressure on the fisheries resources and foster the sustainability of the sector. Despite the global dominance of small vessels, estimations of their numbers are likely to be less accurate, as, unlike industrial vessels, they are often not subject to licensing and registration requirements. The lack of information and reporting is particularly acute for inland water fleets, which are often entirely omitted from national or local registries.
Historically, Japanese pilchard and Alaska pollock used to be the most productive species, with peak landings at 5.4 million and 5.1 million tonnes, respectively. In contrast, landings of squids, cuttlefishes, octopuses and shrimps have increased greatly since 1990. In 2017, two stocks of Japanese anchovy were overfished, while for Alaska pollock two stocks were sustainably fished and another one overfished. Overall, in 2017, about 65.4 percent of the fish stocks monitored by FAO were fished within biologically sustainable levels, and 34.6 percent fished outside of these levels, in the Northwest Pacific. In 2018, inland aquaculture produced 51.3 million tonnes of aquatic animals, accounting for 62.5 percent of the world’s farmed food fish production, as compared with 57.9 percent in 2000. In inland aquaculture, the dominant position of finfish was gradually reduced from 97.2 percent in 2000 to 91.5 percent in 2018, reflecting the strong growth of other species groups, particularly crustacean farming in freshwater in Asia, including shrimps, crayfish and crabs .
A high degree of transparency in science and management is fundamental to enabling fishers, NGOs, other science and management organizations, processers and retailers to have confidence in fisheries management. Possible pathways towards successful implementation of sustainable aquaculture in different regional contexts, based on case studies of accomplishments in similar settings or regions. The OECD–FAO Guidance includes the OECD Guidelines for Multinational Enterprises, the CFS–RAI, and the VGGT. Developing States Parties, constituting the majority of Parties to the PSMA, are key to ensuring widespread implementation of the PSMA.

The project pays particular attention to strengthening access and user rights, co-management and gender equality, while also supporting improved working conditions, product quality and market access along the value chain. Oceans and inland waters are increasingly recognized as indispensable for addressing many of the global challenges facing the planet in the decades to come, from world food security, poverty alleviation and climate change to the provision of energy, natural resources, improved well-being and medical care. Countries are now seeing the need to integrate these important pieces of policy into the national policy framework. The Lokol Kaikai Initiative, a framework for action on food security, and the National Food Security, Food Safety and Nutrition Policy both consider the fisheries sector as one of the main pillars. For the latter policy, fisheries stakeholders have been actively engaged as members in the working committee overseeing its implementation.
In a newly-published study conducted at the University of Salford in Manchester, vitamin C demonstrated its power to stop tumors in their tracks by interfering with cancer stem cell metabolism – suppressing their ability to process energy for survival and growth. Although mainstream medicine has been slow to accept the cancer-fighting properties of vitamin C, the exciting results of this study could help to change that. The results therefore, support the previously assumed positive effects of walking on health and extend them by the concrete positive effects on the brain. Because most psychiatric disorders are associated with deficits in the prefrontal cortex, this is of particular importance to the field of psychiatry.

The study was the first to explore the effects of vitamin C on cancer stem cells – and provided the first evidence that vitamin C, in the form of ascorbic acid, can target and kill them. Cancer stem cells are responsible for triggering tumor recurrence, and promoting their growth and metastasis. Researchers believe that cancer stem cells give cancer its ability to resist chemotherapy and radiation – the reason for treatment failure in advanced cancer patients.
This new FAO app has also been released as an open-source application, and interested organizations are welcome to join and contribute. SmartForms is expected to enhance data collection capacity, including by applying international standards, and should therefore facilitate harmonization of datasets among data collection schemes. SmartForms also constitutes an innovative approach to data collection for sectors that are poorly documented and monitored (e.g. recreational fisheries, and socio-economic information).
Moreover, they do not always consider the local specificities of production systems (Mialhe et al., 2018). As a result, inclusive, non-sectoral, participatory and holistic approaches, such as the ecosystem approach to aquaculture, have been promoted in order to re-establish a satisfactory trade-off between the various local and global dimensions of aquaculture sustainability. The first such approach has promoted traditional sustainable aquaculture systems by giving them due recognition. One example is the designation Globally Important Agricultural Heritage Systems , which, for example, has been awarded to China’s rice–fish system and its mulberry–dyke and fish-pond system .
Consumption of at least 0.67 servings per day of vegetables was associated with a lower risk of COVID-19 infection. Processed meat consumption of as little as 0.43 servings per day was associated with a higher risk of COVID-19. “A person’s nutrition impacts immunity,” said senior author Marilyn Cornelis, associate professor of preventive medicine at Northwestern University Feinberg School of Medicine. “And theimmune systemplays a key role in an individual’s susceptibility and where can i buy cbd capsules response toinfectious diseases, including COVID-19.” A new Northwestern Medicine study shows coffee consumption and eating lots of vegetables may offer some protection against COVID-19. Growing evidence from other research has linkedemotionalprocesses with systemicinflammation, which has been shown to contribute to poorhealth, such as atherosclerosis, diabetes, rheumatoid disease and osteoporosis, and leads to a number of processes that play a major role inpremature death.
In this way, the PSMA reduces the incentive for such vessels to continue operating while, at the same time, blocking fishery products derived from IUU fishing from reaching national and international markets. Salmon, particularly farmed Atlantic salmon, has proved a versatile and popular seafood item that aligns with trends in modern consumer preferences. Driven by strong demand in both developed and developing markets in almost every world region, salmon has become the largest single fish commodity by value. The markets for farmed coho salmon, rainbow trout and wild salmon species from North Pacific fisheries have all experienced growth, but it is Atlantic salmon that accounts for the largest proportion of export revenue. Atlantic salmon aquaculture, led by Norway and Chile, is one of the most profitable and technologically advanced fish production industries globally, while on the market side the industry is notable for coordinated international marketing strategies and a rapid pace of product innovation.
Many fishers and aquaculture farmers are already adapting, but institutions and policies need to follow suit. Promote approaches to fisheries development and governance that build on the principles of the SSF Guidelines. Deploy context-specific messaging through appropriate channels to encourage consumption of diverse nutritious and sustainably produced aquatic foods. Promote appropriate communication and awareness about the impact of illegal fishing on overfishing and fish stock recovery. Encourage appropriate communication, knowledge mobilization and education across all actors involved in decision-making to improve transfer of information and buy-in compliance to regulations to achieve effective management systems. Develop and implement better mechanisms to incorporate multiple types of available information, including local knowledge and expertise, and their integration into assessment and management approaches.
Earthen ponds remain the most commonly used type of facility for inland aquaculture production, although raceway tanks, aboveground tanks, pens and cages are also widely used where local conditions allow. Rice–fish culture remains important in areas where it is traditional, but it is also expanding rapidly, especially in Asia. However, there have been rapid and significant advances in the improvement of integrated inland aquaculture farming systems in recent years, resulting in not only higher productivity and improved resource-use efficiency, but also reduced impact on the environment. Inland water captures are more concentrated than marine captures among major producing nations endowed with important waterbodies or river basins.
The late submission of questionnaires makes it challenging for FAO to process, validate and review the capture fisheries statistics – in particular for the most recent year – prior to the official release of the data, usually in mid-March every year. In the absence of national reports or in the event of inconsistencies in the data, FAO may make estimates based on the best data available from alternative official data sources (including data published by regional fisheries management organizations ), or through standard methodologies. The increase in 2018 was mostly driven by marine capture fisheries, whose production increased from 81.2 million tonnes in 2017 to 84.4 million tonnes in 2018, while catches from inland captures also recorded their highest-ever catches, at over 12 million tonnes. China remained the top capture producer – despite the recent downward revision of its catches for the years 2009–2016 and a decline in reported catches in 2017–2018. China accounted for about 15 percent of total global captures in 2018, more than the total captures of the second- and third-ranked countries combined. The top seven capture producers accounted for almost 50 percent of total global capture production ; while the top 20 producers accounted for almost 74 percent of total global capture production.
Finfish farming, the most diverse subsector, contains 27 species and species groups, which accounted for over 90 percent of total finfish production in 2018, of which the 20 most important species accounted for 83.6 percent of total finfish production . Compared with finfish, fewer species of crustaceans, molluscs and other aquatic animals are farmed. Coastal aquaculture plays an important role in livelihoods, employment and local economic development among coastal communities in many developing countries. It is practised in completely or partially artificial structures in areas adjacent to the sea, such as coastal ponds and gated lagoons. In coastal aquaculture with saline water, the salinity is less stable than in mariculture because of rainfall or evaporation, depending on the season and location.
The researchers will now try to analyse the same indicators in similar population groups, but of European origin, to find out if the results obtained can also be applied outside the United States. The American Heart Association recommends eating oily fish such as salmon, anchovies or sardines twice a week because of the health benefits of omega-3 acids. According to the American Psychological Association, teens report stress well above what they believe to be healthy. 31% of teens report feeling overwhelmed and 36% report feeling fatigued as a result of stress. Over a third of teens report that their stress level has increased in the past year, while around half of teens don’t feel they are doing enough to manage their stress. In light of the findings, investigators encourage physicians to highlight the benefits of physical activity to lower OSA risk.
Ensure that efforts to develop the blue economy are based on sustainable development, and incorporate the rights of those whose livelihoods depend on the sea now and for future generations of fishers. Deficiencies in data collection are still important, but no longer the only driver in data gaps. There is a strong need for developing countries to invest in the capacity to collect, compile and analyse data in fully integrated systems. Respond to climate change by improving fisheries management through the implementation of cross-sectoral, holistic and precautionary approaches that attain robustness to variability, rather than stability. Modify data collection systems to include disaggregated data to account for nutrition, well-being, gender and other dimensions beyond catch. Encourage co-production of information with stakeholders to promote trust and collaboration among governments, academia and small-scale fishing communities, and build capacity to use information.
