A £1.4 million funding has been secured by the University of Stirling to explore tissue remodelling processes in salmon, with a focus on reducing mortality linked to gill and skin health issues. The research will deliver practical tools for fish health and productivity while enhancing sustainability in the Scottish aquaculture industry.
A new resource has been developed to help kelp farmers in Maine reduce their production costs. The tool provides detailed economic analyses and identifies strategies for sustainable business plans. By using this tool, kelp farmers can achieve economic sustainability and improve their bottom line.
A study published in npj Ocean Sustainability reveals that traditional Hawaiian fishponds (loko iʻa) effectively shield fish populations from the negative impacts of climate change. The research found that loko iʻa fish populations were more resilient to rising water temperatures than those in surrounding estuaries.
A new study from the University of Maine compares two common Atlantic sea scallop farming methods, lantern net and ear-hanging. The research found that ear-hanging production is more advantageous when scallops' life cycles exceed three years, with faster rate of production and larger adductor muscles.
Scientists have identified a previously unknown virus in Pacific oysters linked to annual mass die-offs, highlighting the importance of disease prevention measures. The discovery also underscores the need for further research into the causes of mortality in oyster populations.
A new executive order aims to deregulate the US seafood sector, but experts argue it will weaken scientific authority and environmental protections. The policy threatens the sustainability of wild fisheries and aquaculture development, which is crucial for food security.
A study by Chuo University reveals that American eel is widely distributed in processed eel products sold at Japanese retail stores, contradicting the country's primary reliance on Japanese Eel. The research highlights the need for sustainable use of anguillid eels beyond Japanese Eel to ensure their conservation.
A new study reveals the global distribution of FMFO factories, highlighting Peru's high production and potential environmental impacts. The study provides a starting point for addressing these issues through more transparent data, regulation, and sustainable practices.
A new study reveals that Malaysia's capture fisheries have stalled despite being critical to the country's food security and economy. Aquaculture, including farmed fish and seaweed, is now driving growth with seaweed farming becoming a single largest component of aquaculture output.
A new model assesses mariculture's effects on marine species and forecasts its impacts by 2050 under different climate scenarios. Strategic planning can increase production of bivalve shellfish and finfish, but may harm certain iconic marine mammals.
Researchers used drones to map loko iʻa at the community level, providing insights into flooding and future sea level rise impacts. Drones accurately estimated observed flooding during extreme high tide events, while LiDAR models overestimated flooding by two to five times.
A study by University of Hawaii researchers suggests that revitalizing Indigenous aquaculture systems, known as loko iʻa fishponds, can increase locally available seafood production. This revival has the potential to boost local food production and provide a sustainable solution to Hawaiʻi's seafood supply.
A recent study by the University of Cambridge found that farmed salmon production leads to a loss of essential nutrients. Consuming one-third of current food-grade wild feed fish directly could maximize nutrients from the sea. This approach could help address global nutrient deficiencies and improve both diets and ocean sustainability.
Researchers recorded and identified mating and feeding sounds of 21 ocean species, including those influenced by the moon. The study's findings will contribute to the development of the Global Library of Underwater Biological Sounds (GLUBS), an open-access online platform for monitoring changes in marine environments.
A new study finds that seafood farming's growth rate has already peaked in 1996 and is now declining, requiring rebuilding of wild fish stocks to meet future demand. Without this approach, relying solely on aquaculture could lead to a global seafood shortage by 2030.
A new study found that offshore mussel farms can increase species abundance, including Atlantic horse mackerel and European lobster, on degraded seabed habitats. The research suggests that this practice could have wider environmental benefits, supporting the national and international Blue Growth agenda.
Researchers identified Tenacibaculum maritimum, a bacterium causing ulcerative disease, and piscine orthoreovirus (PRV), a virus causing disease in Pacific salmon worldwide. The study links PRV to negative impact on wild Pacific salmon survival in B.C.
Mariculture holds great potential to help satisfy global demand for meat, but requires careful governance and efficient operations. The study suggests that finfish and shellfish farms can increase seafood availability, while maintaining ecosystem health.
Researchers assess predictive skills of ocean heat content in two state-of-the-art seasonal forecasting systems, finding potential to predict sub-surface warming up to two seasons in advance. This could aid mitigation of extreme events and provide early warnings for industries such as aquaculture and fishing.
Mariculture has the potential to deliver high-protein foodstuffs with a significantly reduced carbon footprint compared to terrestrial products. The authors suggest various ways to improve mariculture's sustainability, including supply chain improvements and cofarming practices that can lead to net reductions in CO2 emissions.
A new study projects that farmed seafood supply will drop by 16% globally by 2090 if no action is taken to mitigate climate change. The industry is vulnerable to the effects of climate change, and some regions could see a decline in mariculture production by up to 90%.
Researchers estimate that sustainable seafood production can increase by 21-44 million metric tons annually, accounting for 12-25% of global animal protein needs by 2050. Policy reforms and technological improvements can help address sustainability concerns and environmental limitations.
A team of FSU researchers examined over 50 years of data from 1950 to 2016, finding consistent patterns in mariculture development globally. Countries with stable production farmed a greater diversity of species than those with fluctuating trends.
Researchers have developed guidelines for accurately dating ancient clam gardens, revealing that Indigenous peoples on the Northwest coast have been harvesting shellfish for at least 3,500 years. The study provides new methods for tracking mariculture trends through time, supporting long-term food security practices.
UC Santa Barbara researchers estimate the Caribbean can produce over 34 million metric tons of seafood annually, exceeding current production by two orders of magnitude. The region's vast ocean space makes it an attractive location for offshore mariculture, with some areas showing promise for commercial farming.
