  • CO2 Removal and Stripping Column Ventilation Rate at Bell Aquaculture

    Monitoring and controlling CO2 level in Recirculating Aquaculture Systems (RAS) is crucial not only for fish health but it is used increasingly for efficient management. Under supervision of Steve Summerfelt, a joint project has studied costs savings with optimizing ventilation based on CO2 continuous monitoring. The CO2 probe used in that project came from ...

  • 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 ...

    First of all, there is huge market space for underwater drone. In terms of Fisheries and aquaculture, China's aquaculture area is 8465,000 hectares, of which 27.38% is mariculture area and 72.62% is freshwater aquaculture area. There are 32,000 aquaculture farms in China, covering an area of 10 million hectares. It is necessary to check the temperature, salinity, PH value, dissolved oxygen of ...

  • Benzoylurea pesticides used as veterinary medicines in aquaculture: Risks and developmental effects on non‐target crustaceans

    Diflubenzuron and teflubenzuron are benzoylureas that are used in aquaculture to control sea lice. Flubenzurons have low toxicity to many marine species such as fish and algae, but by their nature are likely to have significant adverse effects on non‐target species such as crustaceans and amphipods. Although the exact mechanism of toxicity is not known, these compounds are thought to inhibit ...

  • Ghana Fish Farming and Fish Feed Production

    There are two main ways to obtain feed for fish farming in Ghana: locally produced feed and imported feed. However, fish feeds locally produced are in bad quality as most of them are not extruded. Imported feed is appropriately 30% more expensive than locally produced. So importation is not a quick fix. On average the costs for Tilapia farming in Ghana consist of 70% of the feed cost. Therefore, ...

  • 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 ...

  • 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 ...

  • Protecting ireland’s aquaculture

    Background Mulroy Bay in North West Ireland is a pristine marine environment with a number of rare and sensitive habitats. As a result Mulroy Bay is designated as a Special Area of Conservation under the EU Habitats Directive (92/43/EEC). The sheltered nature of the bay has seen it develop into a major centre for aquaculture producing shellfish and salmon with an annual value of ...

  • Estimating preferences for non-market attributes of aquaculture and sustainable seafood production: methods and empirical applications

    If aquaculture is to promote sustainable seafood production, the public must be willing to accept associated tradeoffs. Tradeoffs may include impacts on a variety of environmental and social attributes. Public preferences for aquaculture may differ according to type of operation, species, region, and other factors. Stated preference methods can assist policymakers in designing balanced, ...

  • Mangrove Capital

    This paper introduces Mangrove Capital; a programme conceived by Wetlands International and partner organisations, that aims to bring the values of mangroves to the fore and provide the knowledge and tools necessary for the improved management of mangrove forests. The project will enable governments, private sector organisations and local communities in Indonesia to manage mangroves, so that they ...

  • 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 ...

  • Indonesia: Opportunity for shrimp aquaculture - Case Study

    Great opportunities exist in shrimp culture in Indonesia due to land availability and ideal climate. Already, this country is one of the largest producers in the world. Many farmers use AIRE-O2® aerators as their 'aerator of choice' because the 'performance is better than the paddlewheel and the AIRE-O2® aerators keep the bottom of the ponds cleaner,' said the manager at this farm. The P. ...

  • Development of new methods to assess invertebrate immunology and immunotoxicology in aquaculture: oysters and lobsters as examples

    In order to support healthy aquaculture, we developed assays to assess immune functions and their susceptibility to environmental conditions or toxicants. Flow cytometry allowed the rapid and quantitative analysis of oyster and lobster cell subpopulations and their functions (phagocytosis, peroxide production, natural killer cell-like activity and apoptosis). We demonstrated experimentally that ...

  • 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 ...

  • 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 ...
