  • 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 ...

  • 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. ...

  • 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, ...
