Since its inception, aquaculture has developed into a major industrial complex, a major component of which is cage culture. Along with the growth, however, problems arose. Translocations of animals and diseases, as well as concerns over environmental effects limited the growth of the industry. The concept of fish health management whereby the host, pathogen, and environment are proactively mana...

John Lucas introduces aquaculture, the cultivation of aquatic organisms and its role in human food production for a sustainable future.

BACKGROUND Global aquaculture production has increased continuously over the last five decades, and particularly in China. Its aquaculture has become the fastest growing and most efficient agri-sector, with production accounting for more than 70% of the world's aquaculture output. In the new century, with serious challenges regarding population, resources and the environment, China has been wor...

The colorful carotenoid pigments are known as biological active compounds that have beneficial effects on the metabolism of animals and humans. Carotenoids provide protection against several stressors, including UV radiation, reactive oxygen species and free radicals, have important roles in vision, and act as precursors of transcription regulators and in the immune system. Studies on human nut...

This article analyzes spatial and temporal changes of aquaculture land use in Yunlin County, Taiwan, and discusses the driving forces for these changes. Digital land-use maps and satellite imagery for 1982, 1988, 1994, and 2002 were used to extract aquaculture areas. A geographic information system was used to derive changes in aquaculture areas and to compute the spatial clustering statistics ...

Over the past few decades, clearing for shrimp farming has caused severe losses of mangroves in the Mekong Delta (MD) of Vietnam. Although the increasing importance of shrimp aquaculture in Vietnam has brought significant financial benefits to the local communities, the rapid and largely uncontrolled increase in aquacultural area has contributed to a considerable loss of mangrove forests and to...

Fish diseases are one of the major problems in fresh water biota. There is an urgent need in aquaculture to develop microbial control strategies, since diseases epidemics are recognized as important constraints to aquaculture production, trade and the development of antibiotic resistance has become a matter of growing concern. In this study, we evaluated the tilapia fish (Oreochromis mossambicu...

The ultimate objective of an aquaculture feed manufacturer and aquaculture food supplier is to ensure that the feed or food produced is both safe and wholesome. Reported food safety risks, which may be associated with the use of commercial animal feeds, including compound aquaculture feeds, usually result from the possible presence of unwanted contaminants, either within the feed ingredients us...

Betanodavirus is one of the two genera making up the family Nodaviridae and is the etiological agent of viral nervous necrosis (VNN, also known as viral encephalopathy and retinopathy or VER). The virus infects a large range of host species in more than 50 species of marine and freshwater fish worldwide from different geographical areas and the known host range continues to expand as new specie...

The Eastern oyster, Crassostrea virginica, has historically supported a major fishery along the Atlantic and Gulf coasts of North America. Although commercial landings of oysters along the East Coast have been in significant decline for decades, oyster aquaculture has the potential to provide for a sustained commercial harvest as well as to generate a product that is superior to wild-caught oys...
