  • 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 ...

  • Massive freshwater gains from producing food at sea

    Water scarcity may be the most limiting factor to increasing world food production. Irrigation water is already overdrawn beyond sustainable levels and to increase reliance on rainfed agriculture is risky, even more so with climate change. However, to promote deliberate food production at sea, both fished and farmed, and both plant and animal, requires no freshwater or land. The thousands of ...

  • The advantages and disadvantages of culturing fish.

    The advantages and disadvantages of culturing fish. 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. ...

  • Common Fish Diseases and Caused Reasons

    There are literally hundreds of afflictions that can effect the health of farm fish.

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Singapore: red Tilapia spawns profits

    At this research and commercial farm, freshwater red tilapia (Oreochromis , spp.) is a major product, selling live for a premium price. Harvest size is 600 to 700 grams each, following a six month grow-out period. The senior manager reported, 'Operation with AIRE-O2® aerators is quite good and reliable. We are able to sustain good densities of fish in the ponds.' The deputy manager also reported ...

  • 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 ...

  • 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. ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • 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 ...
