  • A novel growth method for diatom algae in aquaculture waste water for natural food development and nutrient removal

    Diatom algae are known to play an important role as primary producers in many diverse ecosystems, including artificial aquaculture ponds where they also aid in maintaining water quality by consuming excess nutrients. But factors influencing their growth are still poorly understood. In the present study the effect of micronutrients, N:P ratio and silica concentration on benthic diatom Synedra ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Pilot scale testing of advanced oxidation processes for degradation of geosmin and MIB in recirculated aquaculture

    The presence of geosmin and 2-methylisoborneol (MIB) in recirculated aquaculture systems has a significant negative impact on the fish production due to poor flavour quality of produced fish and increased risk of rejection by fish processers. Advanced Oxidation Processes has a high potential for removal of geosmin and MIB in water and in this study UV/H2O2 and UV/O3 has been tested in pilot scale ...

  • Sea water treatment for shrimp farming - Case Study

    Global demand for seafood remains high, yet farming shrimps in aquaculture is a tricky business. Disinfection and desalination systems significantly improve the water quality in the breeding tanks, thereby improving the shrimp survival rate. Task Aquaculture - a growth market Shrimps are a popular delicacy, especially in Europe and the USA. According to the ...

  • 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 ...

  • 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. ...

  • 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 ...
