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...
Penaeus vannamei (Pacific white legged shrimp), is an exotic shrimp species introduced to India in 2009, and is currently been extensively cultured along the Southeast coastal region of the Country. The expansion of the industry had resulted in mushrooming up of unapproved hatcheries and farms which do not implement adequate biosecurity measures or good management practices required for farming...
The global aquaculture of penaeid shrimp has grown rapidly during the past two decades. In 1998, world shrimp farmers produced an estimated 737 200 t of whole shrimp (this includes 530 200 t from the eastern hemisphere and 207 000t from the western hemisphere), a record 12% increase from the 660 200 t produced in 1997 (Rosenberry 1998, 1999). The shrimp farming sector suffered a serious setback...
Structural Insights into the Cytotoxic Mechanism of Vibrio parahaemolyticus PirAvp and PirBvp Toxins
In aquaculture, shrimp farming is a popular field. The benefits of shrimp farming include a relatively short grow-out time, high sale price, and good cost recovery. However, outbreaks of serious diseases inflict serious losses, and acute hepatopancreatic necrosis disease (AHPND) is an emerging challenge to this industry. In South American white shrimp (Penaeus vannamei) and grass shrimp (Penaeu...
Background & Objectives: White spot, as one of the infectious viral diseases, has made severe losses in shrimp ponds all over the world. Despite extensive efforts made to deal with and control the disease, white spot continues to be a major health problem in shrimp farms across Iran. In this work, the significance of the risk factors of white spot disease epidemic occurred in shrimp ponds o...
Since the middle of the twentieth century, the shrimp farming industry has shown steady growth along the tropical and subtropical coasts of the world. The world’s cultivated shrimp production in 1950 was 1325 tons, amounting just 0.3% of the total production for these crustaceans, which were mainly extracted from coastal and estuarine environments. Thirty years later, by 1982, the global shrimp...
Shrimp farming is a small but growing industry in New Caledonia. Since 1993, "Syndrome 93" has been affecting New Caledonian shrimp farming industry every cold season, causing severe epizootic mortalities in grow-out ponds and significant losses. Highly pathogenic strains of Vibrio penaeicida are considered the etiological agent of the disease in Litopenaeus stylirostris. On one hand, studies d...
SL2/PU!culture is of central importance to the fisheries sector in Bangladesh. It grew from next to nothing in the early 1970s to contribute about 11% of total exports in the mid-1990s (DOF 1995). No other primary commodity enjoyed such spectacular growth in post-independence Bangladesh. Although shrimp farming has had a significant impact on the economy of Bangladesh, it has had high environme...
Within the past decade, viral diseases have emerged as serious economic impediments to successful shrimp farming in many of the shrimp-farming countries of the world. In the western hemisphere, the viral agents of Taura syndrome (TS) and infectious hypodermal and haematopoietic necrosis have caused serious disease epizootics throughout the shrimp-growing regions of the Americas and Hawaii, whil...
One ecological environment monitoring system of Litopenaeus vannamei farming has been developed in order to protect and regulate the ecological environment of Litopenaeus vannamei farming, halt and reverses the situations in the ecological environment deterioration of Litopenaeus vannamei farming and the little farming success rate. The early warning information of ecological environment degrad...
