As discussed earlier, there are no commonly accepted approaches of assessing the contribution of a given sector such as commercial aquaculture, to economic growth. Using previous studies, such as the one conducted by Timmer (1992), as a foundation, this chapter attempts to develop a framework for measuring this impact for commercial aquaculture. The assessment framework is developed in two step...

The production of appropriate genetically modified organisms (GMOs) offers considerable opportunities for more efficient and more effective aquaculture across a wide range of species. Although this potential is being realized in crop production with over 60 million hectares under cultivation, there has been no commercial use of GMOs in aquaculture. Here we review the nature of GMOs, the range o...

Water quality management is one of the key problems for intensive aquaculture. In order to predict the aquaculture water quality accurately, the paper proposes an Improved Gray Model for aquaculture water quality prediction. The Gray Model is improved and combined with the BP Neural Networks to implement the prediction. The Improved Gray Model serves as the main body for prediction and BP Neura...

Aquaculture development in Africa has lagged far behind that seen in Asia. It currently produces less than 5% of Africa's fish. Over the past decade, however, growing demand, the availability of suitable technologies and growing capacity has produced aquaculture success stories in several countries. In Egypt, for example, aquaculture production has grown 10 fold since the 1990s. In Uganda produ...
