  • Aquaculture Water Quality Workshop Offers Tips to Boost Profitability of Fish Farming

    Healthy water leads to healthy fish and increases the potential for healthy profits for fish farmers. On the other hand, poor water quality can lead to stressed fish, increasing the chance for the animals’ illness and death, and resulting in income losses for farmers, says Matthew Smith, an Ohio State University Extension aquaculture specialist. Water quality management for fish farmers is ...

  • Ecosystem-based farming comes of age

    A new FAO book out today takes a close look at how the world's major cereals maize, rice and wheat - which together account for an estimated 42.5 percent of human calories and 37 percent of our protein - can be grown in ways that respect and even leverage natural ecosystems. Drawing on case studies from around the planet, the ...

  • 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 ...

  • 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 ...

  • First detection of novel flame retardants in Antarctic species

    Groups of chemicals used as flame retardants were present in the bodies of Antarctic rock cod (Trematomus bernacchii), young gentoo penguin (Pygoscelis papua), and brown skua seabird (Stercorarius antarcticus) collected from King George Island, Antarctica. This study is the first to find some of these chemicals in Antarctica, confirming that they undergo long-range transport and can reach ...

  • Ohio State Offers Aquaponics Fish Farming Workshop July 10-11

    An innovative aquaculture program offered by the College of Food, Agricultural, and Environmental Sciences at The Ohio State University will hold a workshop July 10-11 to provide an in-depth look at the increasingly popular fish farming industry. Held at the Ohio Center for Aquaculture Research and Development at Ohio State University South Centers in Piketon, the workshop will offer current and ...

  • Knowledge of spatial dynamics is critical when determining harvest strategies for fish in meta-populations

    New research published in the Marine Stewardship Council’s Science Series highlights the importance of understanding spatial structure and connectivity of meta-population fish stocks when assessing the sustainability of fisheries. Unlike many self-sustaining ‘closed’ populations, meta-populations are interconnected networks encompassing a number of distinct sub-populations that ...

  • Aided by the Sea, Israel Overcomes an Old Foe: Drought

    A hefty tax was placed on excessive household water consumption, penalizing families with lawns, swimming pools or leaky pipes. So many of Mr. Zvieli’s clients went over to synthetic grass and swapped their seasonal blooms for hardy, indigenous plants more suited to a semiarid climate. “I worried about where gardening was going,” said Mr. Zvieli, 56, who has tended ...

  • Increased oestrogen pollution in European rivers could affect development of brown trout

    Brown trout (Salmo trutta) embryos exposed to oestrogen during development hatched earlier, grew more slowly and had a lower heart rate than unexposed individuals, according to a recent Swiss study. These findings may indicate that oestrogen pollution in some European rivers is contributing to the decline of wild populations of such species. Endocrine disrupting compounds (EDCs) affect ...

  • 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 ...

  • 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 ...

  • For lively fish in the water

    For 30 years, trout have been cultivated at the Winkelmann farm in Wietzendorf (Lower Saxony), southeast of the city of Soltau. What started out as a hobby ultimately became a business. Since then, the main goal has been the preparation of fish eggs, caviar (roe). The female trout are brought up in concrete semi-circulating basins and slaughtered after 26 to 29 months as salmon trout. The annual ...

  • Hormones in wastewater disrupt fish reproduction over generations

    Synthetic oestrogens in wastewater from contraceptive pills can have effects on fish reproduction and survival that worsen over several generations, new research has found. The study suggests that some fish populations may not be able to recover from levels of oestrogen pollution found in many freshwater environments. Freshwater ecosystems are increasingly under threat from both climate change ...

  • Pesticides may affect all stages of aquatic life

    Ecotoxicity tests that are used to understand the impacts of chemical pollutants on aquatic organisms and ecosystems could be improved by including all life stages of the test animals. These are the conclusions of a study by Belgian researchers, who found that the apparent absorption of some pesticides by the dormant eggs of water fleas may have negative effects on the invertebrates’ later ...

  • Ethanol`s rise can mean loss of hunting lands

    Pheasants once drew hundreds of weekend hunters to Fairbury, Neb., each fall, filling the 45 rooms at Randy Brown's Capri Motel with sportsmen eager to bag their limits. But times have changed. The native grasslands and milo crops that used to dot surrounding Jefferson County have been overtaken by corn and soy crops. Neither provides the shelter that wildlife once enjoyed. This year's opener ...

  • Salmon and sea trout close season on Hampshire rivers starts today

    The Environment Agency is reminding anglers that today (Thursday 31 October) sees the start of the close season for salmon and sea trout fishing in Hampshire. This means that rivers such as the Lymington, Meon, Test and Itchen will close to anglers who traditionally fish for either of these species. The fishing season for salmon runs from 17 January until 2 October and the season for Sea Trout ...

  • Ohio State Aquaculture Research Program Looking to Recruit New or Beginning Fish Farmers

  • Four million people food insecure in Madagascar

    As many as 4 million people in rural areas of Madagascar are food insecure following this year's reduced harvest. Production of rice – the Indian Ocean island's staple – and maize has been badly hit by erratic weather and a locust invasion. A further 9.6 million people are at risk of food insecurity, say two United Nations agencies. The extent of the island's food crisis is revealed ...
