  • Historic Howietoun fish farm for sale

    SCOTLAND’S first fish farm site has been put up for sale, along with its ponds and outbuildings, set in about 27 acres in Stirling. Historic Howietoun Fishery was established in the late 19th century by Sir James Maitland – described as the father of scientific aquaculture – on his estate near Sauchieburn. In the 1870s, Sir James pioneered scientific trials into trout breeding ...

  • Fish farm parasite drug threatens wildlife

    A drug used to treat parasite infections at fish farms can contaminate the surrounding environment and threaten local wildlife, a new study shows. Following a week-long treatment at a Norwegian salmon farm, the authors found concentrations of an anti-sea-lice drug that were high enough to kill some crabs, shrimps and lobsters. However, they suggest the drug is not likely to pose a risk to humans. ...

  • Environmental impact research urged for fish farming

    More research and sharing of best practice could minimise the environmental impacts of aquaculture, and maximise its potential to alleviate food insecurity, according to a report by the WorldFish Center and the non-profit organisation Conservation International. Almost half of all seafood consumed ...

  • Trialling ocean temperature forecasts for fish farms

    While land farmers have used seasonal forecasting for nearly a decade, marine farmers in south-east Australia have sought the technology for a region identified as a climate change hotspot, with rates of ocean warming up to four times the global average.   CSIRO Climate Adaptation Flagship scientist, Dr Alistair Hobday, said the project, funded through the Fisheries Research and Development ...

  • What are the impacts of fish-farming on marine ecosystems?

    New EU-supported research in the Mediterranean Sea has assessed the impact of fish-farming on seafloor ecosystems. Results indicate that impacts are only apparent in habitats with no vegetation, but the researchers suggest that habitats with vegetation seagrass could be masking the effects. The EU Marine Strategy Framework Directive 2008/56 1 aims to achieve good environmental status of the EU's ...

  • Shifts in Mediterranean fish farming increase pressure on wild fish stocks

    Fish farming in the Mediterranean has increasingly shifted from producing fish such as grey mullet, which are herbivores near the bottom of the food chain, to species such as sea bass, which are predators. This ‘farming up’ the food chain requires wild fish to be caught to provide feed. A return to farming fish lower in the food chain would use marine resources more efficiently, a new ...

  • Timor-Leste embarks on fish farming for food security

    Timor-Leste has embarked on a national fish farming programme in a bid to fight malnutrition and reduce poverty, its government has announced. The national aquaculture development strategy, a combined effort with ...

  • The future of fish farming and marine fisheries for a growing population

    Fish farms, and other forms of aquaculture, are seen as a potential solution to meeting increasing global demand for seafood. However, according to recent research, they must reduce their reliance on wild fish for animal feed if current production levels from both aquaculture and wild fisheries are to be maintained. As the world’s population heads towards the 9.3 billion mark, ...

  • Fish farms to produce nearly two thirds of global food fish supply by 2030

    Aquaculture — or fish farming — will provide close to two thirds of global food fish consumption by 2030 as catches from wild capture fisheries level off and demand from an emerging global middle class, especially in China, substantially increases. These are among the key findings of "Fish to 2030: Prospects for Fisheries and ...

  • Fish Farm Diseases Preventable With Chemical-Free UV Treatment

    PASTURELLA SKYENSIS Today, BBC News unearthed an account where a company in Scotland lost around 125,000 salmon due to an outbreak of the bacterium Pasturella Skyensis. With high concentrations of salmon living in each cage at farms and hatcheries, diseases and bacteria, ...

  • First-ever federal rules for offshore fish farming issued

    The first-ever federal regulations for large-scale fish farming in the ocean were issued Monday, opening a new frontier in the harvesting of popular seafood species such as red drum, tuna and red snapper. The new rules allow the farming of fish in federal waters of the Gulf of Mexico. The rules - in the making for years - were announced in New ...

  • High-Quality Pumps Help Fish Farms Handle Growth

    Pumping systems manufacturer DESMI’s Peter Laursen offers advice to farmed-fish processing plants looking to invest in high-reliability, scaleable pumps to meet production pressures. With fewer and fewer fish in our seas, fish farming has grown to become an enormous industry worldwide – with billions of dollars in revenue and continued growth forecast for decades to come. Like any ...

  • Impact of sustainable feeds on omega-3 levels in farmed fish

    As the global population and its demand for seafood increases, more of our fish will come from aquaculture. Farmed Atlantic salmon are a global commodity and, as an oily fish, contain a rich source of the health promoting long-chain omega-3 fatty acids, eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. Replacing the traditional finite marine ingredients, fishmeal and fish oil, in farmed ...

  • Fish farming finds its way to land-locked Midwest

     The latest of five generations who have worked the same ground in northeastern Nebraska, 52-year-old Scott Garwood, isn't growing corn or cattle - it's fish. Specifically, thousands of an Australian freshwater species called barramundi - often dubbed Asian sea bass because of its similar sweet, white flaky flesh - in large tanks inside a warehouse. With global consumption of seafood ...

  • Rethinking Fish Farming to Offset Its Public Health and Environmental Risks

    As government agencies recommend greater consumption of seafood for its health benefits, a new analysis led by researchers from the Johns Hopkins Center for a Livable Future urges medical and public health professionals to consider the environmental and health impact of seafood sourcing, particularly aquaculture, or the farming of fish, shellfish and crustaceans. The paper appears in the July ...

  • Sea lice pesticides from Norwegian fish farms can exceed UK environmental health standards

    Levels of aquaculture pesticides exceed UK environmental quality standards (EQSs) in samples taken from near Norwegian fish farms, a recent study has shown. The researchers examined five pesticides used to kill sea lice (Lepeophtheirus salmonis) and showed that in many cases their concentrations exceeded UK EQSs. They used UK standards, they explain, because there are currently no Norwegian EQSs ...

  • Scientists say feeding fish soy, not fish, more sustainable

    Research supported by the soybean industry is looking to convert some farm-raised fish into vegetarians. A South Dakota State University fisheries scientist is developing a soy protein feed that's tasty and easily digestible to eventually reduce the industry's need for using wild-caught fish as food for farm-raised fish. Much of the tilapia, Atlantic salmon and catfish that Americans toss into ...
