  • Simulations of nutrient emissions from a net cage aquaculture system in a Brazilian bay

    Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to ...

  • Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study

    Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

  • Nitrogen and phosphorus pollution alter the mutual relationship between corals and algae

    phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution change the relationship between the tropical coral ...

  • Development of algae–based technology to mitigate energy crisis in coal mining areas: a critical review

    Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...

  • 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 ...

  • Ecological swimming pond case study

    In spring 2009 LG Sound installed an LG Sonic in an ecological swimming pond in France. This pond has been suffering from the growth of filamentous algae for a long period of time. Even when the algae where removed, they grew back within a couple of days. Swimming or any other recreational use was made impossible in this pond. The LG Sonic products can shift the balance in a watery ecosystem to a ...

  • Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system

    Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

  • Seasonal Dynamics of Periphyton in a Large Tropical Lake

    Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...

  • A Study on Assessment on Pollution Load from Dairy Effluent

    ABSTRACTBiodegradation is increasingly being considered as a less expensive alternative to physical and chemical means of decomposing organic pollutants. Pathways of biodegradation have been characterized for a number of microorganisms, some of which have been used for remediation of water. Because algae are photoautotrophic their use for bioremediation of surface waters would circumvent the ...


  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • 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 ...

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

    Coastal lagoons are subjected to strong anthropogenic pressures as a consequence of their location between Land and Sea. Among other contaminants, they are receiving high nutrient loadings and pesticides, mainly of agricultural origin, from heavily exploited watersheds. Since the number of chemicals released into the water systems is high, there is a need to classify them and the associated risk, ...


  • Development of a Bioaccumulation Model For Herbicides in Ulva and Clams

    Coastal lagoons are shallow water ecosystems characterised by high biodiversity and primary and secondary production, and with an elevated number of different habitats. These habitats have a key role as nursery and rest areas for a great number of marine species and birds. During the last decades these ecosystems have been exposed tomany anthropogenic pressures (urban, domestic, agricultural ...
