  • The benefit of electrocoagulation in water treatment for agriculture and aquaculture

    Now a day’s one of the most intensive and the best field due to which the entire human kind can survive is the field of agriculture and aquaculture. The agriculture industry is a water requirement industry and is in a need of constant free contaminant water supply and so is in fish cultivation. And in order to provide this contaminant free water supply it requires a large scale of water ...

  • Study on method and mechanism of deep well circulation for the growth control of Microcystis in aquaculture pond

    In order to control the growth of Microcystis in aquaculture ponds and reduce its adverse effect on water quality and aquaculture, a production-scale experiment of deep well circulation treatment was carried out in an aquaculture pond with water surface area of 63,000 m2 and water depth of 1.6–2.0 m. Compared with the control pond, the experiment pond had better water quality as ...

  • 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 ...

  • Ecological impacts of fluridone and copper sulphate in catfish aquaculture ponds

    Fluridone and copper sulphate are often used for controlling macrophytes and algae in aquaculture ponds. The present study examined the ecological effects of these chemicals on macrophyte, phytoplankton, and zooplankton biomass, plankton community structure, water quality parameters, and fish survival and yield in catfish culture ponds using a randomized complete block design. The estimated ...

  • Effects of different management regimes on mangrove ecosystem services in Java, Indonesia

    This new report, published by Wageningen University and Wetlands International, seeks to fill a significant gap in mangrove ecosystem service estimates. While several studies have sought to measure and value the ecosystem services provided by mangrove ecosystems in general, this new piece of research has for the first time conducted separate evaluations for zones that are characterised by ...

  • Evaluating alternatives for decommissioning California's offshore oil and gas platforms

    This paper introduces a series of six additional papers in this issue that describe an in‐depth analysis of options for decommissioning oil and gas platforms offshore southern California. While current leases require lessees in both state and federal waters to completely remove all production facilities and restore the seafloor to its pre‐platform condition, other options have emerged since ...

  • Utilization of inland saline water for Spirulina cultivation

    An attempt was made to assess the suitability of the inland saline water of Rohtak (Haryana) for mass cultivation of Spirulina platensis, a salt loving cyanobacterium. Cultivation of S. platensis was performed in indoor and outdoor culture units. The investigation revealed that the yield of biomass in de-calcified inland saline water was comparable to the yield obtained in ...

  • Cultivation of microalgae (Oscillatoria okeni and Chlorella vulgaris) using tilapia-pond effluent and a comparison of their biomass removal efficiency

    The uptake of dissolved nutrients by microalgae is the primary way to remove nitrogen in aquaculture systems. Many authors have studied the use of microalgae to treat wastewater from aquaculture. However, excessive microalgae accumulation may cause high levels of organic matter and suspended solids in the final effluent. Thus, an efficient way to remove excess algae is needed in wastewater ...

  • 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 ...

  • Bioeconomic modelling and salmon aquaculture: an overview of the literature

    Bioeconomic models can be used to assist producers and decision-makers in identifying optimal production system designs, operation management strategies, and alternative development and policy approaches. This paper reviews the literature on bioeconomic modelling in aquaculture since 1993 and builds on an earlier article by Leung (1994) which examines this literature for the 1974-1993 period. In ...

  • The status of USA's commercial fisheries and management and crystal-balling the future

    Despite the enormity of the commercial fishing industry of the USA, the structure of the industry and various interactions are not known on a national basis. The US public wants seafood, but current domestic production capabilities appear to be inadequate to support the growing demand for seafood. Imports, particularly aquacultured products, are increasing and expected to further increase in the ...
