Efforts are on the way on the Swedish West Coast to develop the capacity for cultivation of marine resources, notably of kelps. Given that this is a region of great natural and national heritage, public opposition to marine developments has been identified as a possible risk factor. This survey thus sought to shed light on awareness levels, perceptions of different types of aquaculture and on r...

Soil samples were collected from four aquaculture ponds (yellow perch culture), a control pond (without aquaculture activities, fallow pond), crop land (under corn), and forest land to estimate the carbon (C) sequestration potential in the Piketon county, Ohio, USA. The averaged total of C was 6.5 ± 2, 8.8 ± 2, 8.53 ± 0.2 and 10.49 ± 1.1 Mg/ha (Mg=10(6)g) in < 0.25 mm fraction; 15.2 ± 2, 16.0 ±...

Aquatic animal diseases are the most significant constraint to the development and management of aquaculture worldwide. As aquaculture is growing rapidly and poised to help in bridging the gap in the global supply and demand of aquatic animal food products, management of health and reducing losses due to disease in aquaculture is gaining high priority. One of the key areas of success in managin...

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,...

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...
