Heavily discussed topic, but still... Recent studies disclose that nearly two-thirds of global coral reefs are overfished, with over 2,000 reef sites analyzed. This crisis impacts around six million people reliant on reef fisheries for livelihood. In some areas, reef catch comprises up to 43% of total marine fisheries, highlighting the critical role reefs play in global food systems. Transitioning towards sustainable fishing is imperative. By utilizing Open Food Chain, we can trace our seafood's journey, support responsible fishing, and contribute to marine ecosystem restoration. What do you think we should do to tackle overfishing? #SustainableFishing #OpenFoodChain #MarineConservation #Traceability

How are coral reef fisheries doing, and how can they be managed sustainably? This question has been difficult to answer, largely because coral reef fisheries are notoriously data-poor and target multiple species. In a new study led by Jessica Zamborain Mason, a new approach based on extensive underwater visual surveys from around 2000 reefs provides some answers, establishing sustainable reference points in the form of maximum multispecies sustainable yield (MMSY) and fish community biomass at MMSY by accounting for local environmental factors such as temperature and coral cover. Some insights: - reference points can vary among reefs by an order of magnitude, depending on local conditions - in nearly two-thirds of all assessed fished reefs, more biomass is removed than what is sustainably produced - i.e. there is overfishing - at nearly one in ten fished reefs, fish stocks are collapsed: there is less than 10% of the fish biomass they could have if not fished at all - more than half of the fished sites could increase their yields sustainably if adequately managed The study also looked at important ecological functions and processes, such as parrotfish scraping or the number of fish species, showing how fisheries management could best address both, socio-economic and conservation goals.

🌊 A new study by David Gill of Duke University compares the impact of marine protected areas: 🔵 No-take MPAs increased fish biomass by 58.2% 🟢 Multiple-use MPAs saw a 12.6% increase 🔵 Both types are likely to improve fish populations by over 97% 🔍 Context matters: no-take MPAs are more effective near populated areas 🌎 Multiple-use MPAs are a viable alternative in specific conditions 🌿 Read the overview here - https://lnkd.in/ghsssYAs #marineconservation

Because of the urgent global calls to fight climate change by reducing reliance on fossil fuels, more and more companies in the aquaculture industry are using solar energy. Solar energy is a very necessary and viable alternative because of the benefits it provides: low operation cost, long life- cycle, environmental friendliness, no CO2 emissions, and low soil contamination. To ensure sustainability, the energy-intensive aquaculture industry needs to use renewable energy. https://lnkd.in/efsPgSut

🌊 The Maugean Skate, one of the most threatened ray species in the world, is found only in Tasmania's Macquarie Harbour. It is facing extinction due to pollution from non-native Atlantic Salmon farming in pens across the ecosystem, which decreases critical oxygen levels in its habitat. Climate change is also exacerbating these impacts, threatening the skate's fragile marine ecosystem. If these threats continue, the Maugean Skate could become Extinct within a decade. Re:wild partner, Bob Brown Foundation, is working to protect this species in Tasmania. Despite some regulatory efforts, improvements to salmon farming practices in Macquarie Harbour have not been adequately met, significantly impacting the Maugean Skate. To protect this unique species, salmon farming must be removed or at least drastically reduced from this ecosystem to lessen nutrient pollution and improve water quality. Habitat restoration is also critical to support the skate's breeding efforts, while continuous monitoring and research can help guide targeted conservation.

Nice new paper on harvest control rules and management strategy evaluation in fisheries for the case of non-stationary parameters. While the paper doesn't really talk about why parameters are changing over time. One obvious example would be climate change. It can be difficult to causally attribute changes in the environment to soemthing like climate change. However, we do know that cliamte change is leading to a situation of change in which environmental and ecological relationships can be thought of as non-stationary. This model is well-suited to account for such changes.

World's first floating wind power-fishery integrated platform now operational in SE China's Fujian. The world's first floating wind power-fishery integrated platform started official operation at the Nanri Island offshore wind farm in Putian, southeast China's Fujian Province, on Friday, as part of China's efforts to support oceanic green development through an innovative model to produce marine green products and clean energy. Located at the center of the platform is a hexagonal water pool, beneath which lies a double-layered aquaculture net cage capable of accommodating 50,000 deep-sea fish. This innovative design enables the platform to simultaneously generate power on water and facilitate fish farming underwater. According to the staff, the development and construction of the wind power-fishery integrated platform is a multifaceted interdisciplinary project, involving research in energy and power as well as fish farming.

AI-powered data-limited stock assessment method more accurate than 'gold standard' in predicting sustainable fisheries catches - SeaAroundUs: A recent update introduced to the CMSY methodology used to assess the status of fish stocks has proven to more accurately predict the catch that a population can support than highly-valued data-intensive models. https://lnkd.in/gkgBs3da

New projections highlight potential climate risks to exploitable fish biomass in almost all regions of the world’s oceans, including major producing countries and those with a high dependence on aquatic food. Clearly outlining this profile is a recently published report by the Food and Agriculture Organisation of the United Nations (FAO). Global projections of exploitable fish biomass show declines of more than 10 percent, particularly in the high emissions scenario, by mid-century for many regions of the world, according to the paper Climate Change Risks to Marine Ecosystems and Fisheries: Projections to 2100 by the Fisheries and Marine Ecosystem Model Intercomparison Project. #FAO #sustainability #bluetransformation #blueeconomy
