  • Species diversity and ecology of Tonle Sap Great Lake, Cambodia

    Abstract.  Tonle Sap Great Lake in Cambodia, the largest natural freshwater lake in southeast Asia, is situated within the floodplain of the Mekong River. Water levels in the lake vary by about 8 m between the dry season minimum and the wet season maximum when waters from the Mekong River back up the Tonle Sap River. The lake is highly productive – the annual fish catch from the Lake is ...

  • Fish Farms - Inspections below the surface

    Fish farms are tackling the increased demand for aquatic food, while underwater drones are tackling regular and ongoing inspections to ensure fish health and the integrity of the enclosures. According to the Food and Agriculture Organization of the United Nations, by the year 2050, there will be nearly 2 billion more humans populating the earth. Meaning that we will need to produce ...

  • Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries

    The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

  • Hexabromocyclododecane in consumer fish from South China: Implications for human exposure via dietary intake

    Levels of hexabromocyclododecane (HBCD) were determined in 12 consumer fish species from South China. The concentrations of the sum of HBCD diastereoisomers (ΣHBCD) ranged from nondetectable to 194 pg/g wet weight, with a detectable frequency of 70%. This was at the low end of the concentration range globally observed. Carnivorous fish species contained higher HBCD concentrations than herbivorous ...

Experts develop practical recommendations for decision-makers, scientists and producers for a sustainable development of Mediterranean aquaculture. Human demand for fish is growing steadily. With fisheries decreasing worldwide, aquaculture is becoming an important socio-economic alternative and a source of proteins and healthy oils. ...

  • The Scoop on Shellfish Aquaculture

    The centerpiece of many culinary gurus''stunning' dishes, a shellfish’s journey often begins on a farm. Found on the coastal shores or in freshwater lakes, you’ll discover suspended shellfish aquaculture systems.

  • Building a filter defense against Zebra and Quagga mussles

    Tiny mussels can create massive problems for intake structures, vaLves, pumps, screens and other water infrastructure around the US. Some filtration systems can provide chemical-free protection against invasive zebra and quagga mussels, but it is vital to understand the problem and develop the right system to avoid being overrun by the alien species. Zebra mussels (Dreissena polymorpha) and their ...

  • Top trends conservationists should be paying attention to — but aren’t

    Artificial intelligence, testosterone and ship tracking technology probably aren’t on many conservation organizations’ “top things to think about” lists right now. But they should be, suggests a new report in the scientific journal Trends in Ecology & Evolution. ...

  • Analysis of Selected Herbicides And Related Metabolites in a Coastal Lagoon Under The Influence of Water Runoff: Water Column

    Anthropogenic release of chemical contaminants, in particular pesticides coming from agricultural areas, significantly impacts European aquatic ecosystems. Pesticides and herbicides used in common agricultural practices, are applied only during specific periods of the year, leading to significant seasonal peak concentrations in fresh and coastal waters, particularly in spring after heavy rainfall ...


  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...

  • Transgenic fish are ready for us. Are we ready for them?

    After decades of regulatory and legal challenges, AquaBounty aims to bring genetically engineered salmon to U.S. and Canadian markets next year. On a hill above the cold waters around Prince Edward Island, technicians painstakingly create fertilized Atlantic salmon eggs that include growth-enhancing DNA from two other fish species. The eggs will be shipped to ponds in the high rainforest of ...

  • Environment at a Glance

    Since 2000, progress is visible in emissions of traditional air pollutants, transport fuel efficiency, energy intensity, renewable energy, water use, sewage treatment, and biodiversity protection. This is partly explained by the slowdown in economic activity following the economic crisis, but also by increased uptake by OECD countries of instruments to address environmental pressures, including ...
