  • 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, ...

  • 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 ...

  • Processing and Application of Floating and Sinking Fish Feed

    In virtue of mature processing technology and unique advantages in fish farming, extruded floating and sinking fish feed has become the most ideal fish feed in modern aquaculture industry.

  • 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. ...

  • Enhancing competitiveness, product quality and market integration of small mussel growers: a South African case study

    The key proposition in this paper is that the competitiveness of small firms operating in emerging economies and producing highly perishable products (e.g. mussels) is largely contingent on their ability to contend with high Transaction Costs (TC). The study examines the role of contracting in reducing TC associated with small-scale mussel farming in South Africa. Market risks, uncertainties, ...

  • 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 ...

  • Modifications of macrobenthos assemblages on land–based fish farm phytotreatment basins in the Orbetello lagoon

    In the Orbetello lagoon basin there are some intensive land–based fish–farming facilities which contribute to cause a significant cyclic development of the opportunistic chorophycea Ulva laetevirens, and consequent serious decay events in spring and summer. To minimise the nutrients' impact, fish farming was supplied with phytotreatment system. The purpose of this study was to ...

  • Open sea-based Aquaculture case study

    Salmon farming is a multi-billion dollar global industry facing considerable difficulties posed by growing pressure from environmental regulatory bodies. Because marine organisms grow on and “foul” synthetic nets, oxygen available to fish is reduced and infectious diseases and parasites can spread among the fish. A test to study the reduction of fouling formation on netting of fish ...

  • 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 ...

  • 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 ...
