  • 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 ...

  • 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, ...

  • Historic Howietoun fish farm for sale

  • 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 ...

  • 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 ...

  • UV water disinfection in fish farms and hatcheries

    To protect fish farms and hatcheries from outbreaks of water-borne diseases, water treatment specialist Hanovia Limited has developed a high intensity UV disinfection system. Capable of treating up to 700m3/hr of both fresh or sea water with at least a 99.99% kill rate, the UV system can be used to treat both incoming and recirculation water, allowing flexibility in the choice of site and a rapid ...

  • 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 ...

  • US fish farms tap former coal mines for water

    In the Appalachian mountains of the United States, growing numbers of fish farmers are raising trout, catfish, and even salmon throughout the valleys of the state of West Virginia. What they'd rather not tell you, however, is that the source of their water is deserted coal mines. Worry not, seafood lovers. According to independent experts from within West Virginia and outside the state, the ...

  • 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 ...

  • Things to know about marine aquaculture

    Some 90 percent of seafood consumed by Americans is imported, yet the Obama administration's push to expand U.S. marine aquaculture into federal waters has failed to see one offshore farm in operation, nearly two years after the first permit was issued. The National Oceanic and Atmospheric Administration is pushing for marine aquaculture production in the U.S. to jump by 50 percent by 2020. The ...

  • Norway fish farmers bid millions for licences

    NORWAY’S fish farmers have spent tens of billions of kroners at auction buying new salmon production licences as a prelude to a major expansion of the industry. The result is that 160 coastal communities will received at least NOK 2 billion (almost £200 million) in development funding. The Oslo government decreed two years ago that those communities where fish farms are based ...

  • Seaweed study boosts prospects for marine biofuels

    Seaweed biofuel farms have come a step closer to reality with an improvement in the way seaweed sugars can be converted to ethanol. Dried seaweed can be fermented to produce ethanol but breaking down galactose, the dominant sugar in seaweed, is a slow process. Now, researchers have modified the expression of three genes of the yeast Saccharomyces cerevisiae, which is used in the fermenation ...
