Abstract: It was important to sustainable development of aquaculture industry used biological method and biotechnology to treat the waste of aquaculture. In this paper, an airlift recirculating aquaculture system was designed and polychaete worms was cultured in it. According to the different food level experiment, the growth of Perinereis aibuhitensis was tested in each system which marked M1,...
In recent years, Aquaculture has an important role to play in The production of animal proteins, employment, and poverty reduction, especially in rural areas. Water supply as a limiting factor in developing countries. Therefore, Multipurpose use of water resources, including, Water use at integrated aquaculture-agriculture farms is a Strategies for Sustainable Development in the world. The aims...
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...
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...
