Aquaculture is emerging as the fastest growing food-producing industry in the world because of the increasing demand for food fish consumption. However, the intensive culture of food fish has led to outbreaks of various bacterial diseases, resulting in annual economic losses to the aquaculture industry estimated at billions of dollars worldwide. Feeding infected fish with antibiotic-medicated f...

With the rapid development of the fisheries, aquaculture species have degraded, especially for high-density aquaculture of random discharge of industrial wastewater and domestic sewage so that capacity of self-purification and regulation of ponds reduced, and water environment exacerbated. For instance, baits and feces entered into the water in the farming mode of main feeding, so that the amou...

Oysters with potential for aquaculture are found throughout the tropics and subtropics, but few species have been cultured and in only a few tropical countries. This monograph reviews the biology, ecology and culture techniques, both experimental and commercial, used in the tropics; describes the problems associated with tropical oyster farming; and points out research needs to develop further ...

Aquaculture production of molluscs is worth US$11 billion per year and represents 65% of World mollusc product. A significant limitation to the industry is loss of stock through bacterial disease. Traditional methods to combat disease with antibiotics have been questioned and alternatives have been sought. The field of probiotics as well as the screening methods used to acquire probiotic strain...

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,...
