Increased adoption of new activities such as aquaculture into existing agroecosystems calls for the application of simulation models to analyze and forecast consequences of new agroecosystem designs (Elliot and Cole, 1989; Edwards et al., 1988). The main objective of integrated systems is to enhance nutrient cycling and energy flow in the system to obtain maximum benefits in the production of f...

This paper presents work on retrofitting of high-tech systems (HTS) in land-based aquaculture system for improving production efficiency. The objective is to develop architecture for an automated system for aquaculture farming. We call this development an automated expert system architecture (AESA). The article has been organized into four parts. First, it reviews the background and business op...

Apparent amino acid availability coefficients of several typical and novel feed ingredients were determined in rainbow trout using extruded diets and the faecal stripping technique. The ingredients were tested included five fish meals, three terrestrial animal by-products, five plant protein concentrates, four plant meals, and seven low-protein plant ingredients. Amino acid availability from th...

The “Aquaculture Big Numbers” research project seeks to: provide baseline information on the present status of the aquaculture sector from a human development perspective; identify the types and numbers of people employed by the sector; and explore the role of aquaculture in providing social and economic services at a global level, with a particular emphasis on small-scale stakeholders. The res...

grey mullet (mugil cephalus) is an important food fish species in the, mugilidae which is able to adapt in a wide range of salinities and temperatures and is suitable for introduction of the species to freshwater, brackish, and brine waters for aquaculture. this study was implemented to determine appropriate normative of stocking density and initial weight ofmugil cephalus and also evaluate eff...

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...

Aquaculture has been an important economic sector in Vietnam due to its rapid growth and considerable contribution to national fisheries production. With data collected from a field survey interviewing 120 fish farmers in southern Vietnam, this study uses a cumulative logistic model to extend the satisfaction approach to an analysis of the farmers’ satisfaction with their fish farming. Regressi...

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...

Received: 06, May, 2015 Final Accepted: 11, June, 2015 Published Online: 16, June, 2015 Aquaculture is an activity that has many interactions with the surrounding environment using resources and producing changes in the ecological system. Aflatoxins are distributed worldwide. Aspergillus species are able to grow in a wide variety of substrates and under different environmental conditions. Toxin...
