  • Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment

    Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

  • Nutrient-Balance Modeling as a Tool for Environmental Management in Aquaculture: The Case of Trout Farming in France

    The control and prevention of nutrient pollution from fish farming plays an essential role in the French regulatory framework. Assessing nutrient emissions from fish farms is important in terms of farm authorization, taxation, and monitoring. Currently employed strategies involve both water sampling and empirical modeling. This article reports the work and outcomes of an expert panel that ...

  • Phosphatase activity and specific methanogenic activity in an anaerobic reactor treating sludge from a brackish recirculation aquaculture system

    Anaerobic treatment of high salinity sludge from marine/brackish recirculation aquaculture systems is potentially limited by inhibition of enzymatic activities and cell lysis resulting from high osmotic pressures. To further address these limitations the following investigations were conducted: effect of salinity on phosphatase activity (PA), soluble microbial products (SMP) production, and ...

  • Measurement of the amount of DissolvedOxygen

    Dissolved Oxygen (DO) is the term used for the measurement of the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and waste water treatment, the level of DO must be kept high. For aquaculture if the DO level falls too low the fish will suffocate. In sewage treatment, bacteria decompose the solids. If the DO ...

  • Case study - Viet-Uc, Vietnam

    One of the best known growth stories in Vietnamese aquaculture is shrimp producing company Viet-Uc. The business, run by entrepreneur Van Thanh Luong, has set up the world’s largest shrimp hatchery producing 15 billion of postlarvae annually. Applying hatchery management principles – controlling conditions from start to finish – to the nursery and grow-out stages, Viet-Uc is ...

  • 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 ...

  • Rising Meat Consumption Takes Big Bite out of Grain Harvest

    http://www.earth-policy.org/data_highlights/2011/highlights22 World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption. ...

  • Overfishing Threatens Critical Link in the Food Chain

    The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Science’s role in growing diverse, nutritious food

    Can science meet the demand for more diverse and nutritious food? Jan Piotrowski investigates. The riots that swept Africa in 2007 and 2008 in response to the spiralling costs of staple crops brought the effects of food shortages into sharp focus. Images of unrest circled the globe, and the consequent instability brought to the forefront of political debate a question that had ...
