  • Use of Aquaclean in freshwater shrimp production

    The increase in popularity of freshwater shrimp (Macrobrachium Rosenbergii) production has prompted researchers to develop better and more efficient production methods. The current production methods are sufficient to justify the growing of freshwater shrimp, however, to stay competitive long term in the market place, producers will have to increase yields and reduce costs. Current niche markets ...

  • It’s time to stop overspending our freshwater budget

    If freshwater is to remain a renewable resource, we must balance supply and demand on farms, in cities, in industry and in power production. When you look to the year ahead, what do you see? Ensia recently invited eight global thought leaders to share their thoughts. In this interview with Ensia contributor Lisa Palmer, World Resources Institute Global Water Program director Betsy Otto responds ...

  • 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 ...

  • 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 ...

  • A Global Assessment of the Water Footprint of Farm Animal Products

    The increase in the consumption of animal products is likely to put further pressure on the world’s freshwater resources. This paper provides a comprehensive account of the water footprint of animal products, considering different production systems and feed composition per animal type and country. Nearly one-third of the total water footprint of agriculture in the world is related to the ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. Fixed on ropes, plastic trays or in mesh bags, these shelled, aquatic invertebrates are raised in a controlled environment ...

  • 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 ...

  • The water footprint of soy milk and soy burger and equivalent animal products

    As all human water use is ultimately linked to final consumption, it is interesting to know the specific water consumption and pollution behind various consumer goods, particularly for goods that are waterintensive, such as foodstuffs. The objective of this study is to quantify the water footprints of soy milk and soy burger and compare them with the water footprints of equivalent animal products ...

  • Comparative attributional LCA of annual and perennial ligno‐cellulosic feedstocks production, under Mediterranean climate, for bio‐refinery framework

    Annual fiber sorghum (FS) and perennial giant reed (GR) cultivated in the Mediterranean area, appear of interest due to their high productivity under drought conditions and the potential use as lignocellulosic feedstock for biorefinery purpose. This study compares the environmental constraints related to FS and GR produced in an experimental farms (Campania region), by means of an ...

  • Mitigation options for sediment and phosphorus loss from winter-sown arable crops

    Received for publication January 20, 2009. Sediment and P inputs to freshwaters from agriculture are a major problem in the United Kingdom (UK). This study investigated mitigation options for diffuse pollution losses from arable land. Field trials were undertaken at the hillslope scale over three winters at three UK sites with silt (Oxyaquic Hapludalf), sand (Udic Haplustept), and clay (Typic ...

  • 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. ...

  • Insecticide risk map exposes threat to aquatic life

    The global threat that insecticides pose for aquatic biodiversity has been revealed in a recent modelling study that pinpoints areas at greatest risk. The mapping exercise conducted by the researchers reveals that aquatic life in water bodies within 40 per cent of the global land surface is at risk from insecticides running off the ...

  • 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 ...
