  • What`s for dinner? Genetically engineered salmon OK`d by FDA

    What's for dinner? Before long, it may well be genetically modified salmon, the first such altered animal cleared for human consumption in the United States. Critics call it "frankenfish," but the Food and Drug Administration granted its approval on Thursday, saying the faster-growing salmon is safe to eat. It could be available in a couple of years. "There are no biologically relevant ...

  • Sustainable fishing: the dangers of ignoring sub-stocks

    In Europe, some fisheries have been driven to near collapse - most notably cod stocks in the North Atlantic. A recent study warns of the potential dangers of using a single-management technique across a whole species. Instead, distinct populations should be identified with tailored management techniques where necessary. Over-fishing and a changing climate are placing extreme pressures on many ...

  • Vaccination of farmed fish good for animals and thus for humans

    More than half of the fish consumed worldwide is cultivated in ponds or tanks. And the percentage of cultivated fish in relation to wild fish is increasing. The scale on which fish are currently farmed makes it necessary to protect them, by means of vaccination, against disease and premature death. An understanding of the immune system in fish will hopefully lead to effective vaccination methods ...

  • 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 ...

  • 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 ...

  • USSEC’s Indian Aquaculture Team Learns Production Technologies for New Fish Species in Vietnam

    USSEC’s Southeast Asia (SEA) and Asia Subcontinent (ASC) regions teamed up to educate a team of 14 aquaculture entrepreneurs on hatchery and farm production technologies for new fish species. The focus was on a high value fish variety called the murrel, which fetches $4.50 – $ 7.00 per kilogram (whole fish), depending on the market region. This fish is easily farmed in China and SEA, ...

  • Lockheed Martin´s Technology-Infused Mobile Fish Pen Named A Top 25 Invention By TIME Magazine

    You've heard the old saying — there are plenty of fish in the sea — however, this may not always be the case. The inability of wild fisheries to supply the burgeoning demand for healthful and protein-rich seafood has given rise to a ...

  • Can managed introductions boost threatened populations?

    Supplementing declining salmon populations with fish from other, genetically distinct populations may not be the best method of conservation, according to a recent study. The researchers found that for certain salmon populations in France such introductions resulted in offspring with lower body weight and length, possibly worsening their decline. Some previous studies have found that ...

  • Breeding more uniform Nile Tilapia

    For fish farmers, uniformity of growth and body size is one of the key traits to be improved in future breeding programs. In domestic Nile Tilapia size differences among individuals are very large but the genetic background of this variability is almost entirely unknown. In a new study, published by Genetics Selection Evolution, researchers of Wageningen UR found that variability of harvest ...

  • Engineered salmon may be a tough sell

    Don't expect to find genetically modified salmon - or any other engineered fish or meat - on store shelves anytime soon. The Obama administration has stalled for more than four years on deciding whether to approve a fast-growing salmon that would be the first genetically modified animal approved for human consumption. During that time, opponents of the technology have taken advantage of ...

  • New Project to Facilitate Transnational Access to Leading European Aquaculture Research Facilities

    AQUAEXCEL2020, a research infrastructure project funded under the EU’s Horizon 2020 programme and coordinated by the French National Institute for Agricultural Research (INRA), has kicked off this month with the aim to further support the sustainable growth of the European aquaculture sector. AQUAEXCEL2020 will integrate a large group of leading European aquaculture research facilities and ...

  • Starts a breeding program for lumpfish

    Namdal Rensefisk and AquaGen has today signed an agreement for the establishment and running of a breeding program for lumpfish. AquaGen is responsible for developing a genetically improved breeding material, and Namdal Rensefisk will produce offspring with features that are better adapted to the farming conditions and their function as a delouser of salmon. The results so far show great ...

  • Barcoding blitz on Australian moths and butterflies

    Conducted in collaboration with the Atlas of Living Australia (ALA) as part of the International Barcode of Life (IBoL), the project involved extracting DNA from each specimen to record its unique genetic code and entering the results, together with an image and other details, to the ALA and ANIC databases. ANIC is the first national collection to integrate the new barcoding approach for a major ...

  • The gene for sexual maturation in salmon is found

    The discovery of the gene that controls sexual maturation in female and male salmon provides new effective methods of controlling sexual maturation in farmed salmon. The new knowledge will also be of great importance in the management of wild salmon stocks. Maturation in salmon reduces growth, fillet quality and activity of the immune system. This leads to poor fish welfare and downgrading of ...

  • Herring organs damaged by acidified seawater

    Ocean acidification could damage the organs of Atlantic herring, as well as slow their growth and development, recent experiments show. It adds to the list of pressures currently threatening this commercially important species, including over-fishing and marine pollution. Our oceans are changing as high levels of atmospheric CO2 dissolve into seawater and lower its pH to become more acidic. The ...

  • Surrogate sushi: Japan biotech for bluefin tuna

    Of all the overfished fish in the seas, luscious, fatty bluefin tuna are among the most threatened. Marine scientist Goro Yamazaki, who is known in this seaside community as "Young Mr. Fish," is working to ensure the species survives. Yamazaki is fine-tuning a technology to use mackerel surrogates to spawn the bluefin, a process he hopes will enable fisheries to raise the huge, torpedo-shaped ...

  • World fisheries must prepare for climate change

    The fishing industry and national fisheries authorities must do more to understand and prepare for the impacts that climate change will have on world fisheries, says a new FAO report published today. According to the latest edition of the UN agency's The State of World Fisheries and Aquaculture (SOFIA), existing responsible fishing practices need to be more widely implemented and current ...

  • Transgenic Corn Found to Damage Stream Ecosystems

    BLOOMINGTON, Indiana, October 11, 2007 (ENS) - A widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems, finds a new study by an Indiana University professor of environmental science and his colleagues. Pollen and other plant parts containing toxins from genetically engineered Bt corn are washing into streams near cornfields and harming a ...

  • Overcoming Smallholder Challenges with Biotechnology

    A new FAO publication calls for greater national and international efforts to bring agricultural biotechnologies to smallholder producers in developing countries. The publication, Biotechnologies at Work for Smallholders: Case Studies from Developing Countries in Crops, Livestock and Fish, asserts biotechnologies can help ...
