Testing of a pond‐side molecular diagnostic tool for the detection of white spot syndrome virus in shrimp aquaculture
Minardi, D., K.S. Bateman, A. Kuzdzal, M. Stone, J. Avant, R. Condliffe, P. Brotherton, M. Laverick, K. Sritunyalucksana, O. Itsathitphaisarn, P. Baoprasertkul, and G. D. Stentiford
White spot syndrome virus (WSSV) is the most economically important disease of shrimp, and early diagnosis is critical to minimize losses. Current diagnostic methods are expensive, time consuming, and require specialized laboratory equipment and personnel. Minardi et al. (2019) describe the development and application of a new diagnostic test that is easy to use on farms by non-experts. It is affordable and results are available in 70 minutes.
Update on early mortality syndrome/acute hepatopancreatic necrosis disease by April 2018
Prachumwat, A., S. Taengchaiyaphum, N. Mungkongwongsiri, D. J. Aldama-Cano, T. W. Flegel, and K. Sritunyalucksana
Early mortality syndrome/acute hepatopancreatic necrosis disease (AHPND) first appeared in 2009, causing serious losses of shrimp. Prachumwat et al. (2019) describe the length of time to identify the causative agent, develop rapid detection methods, and reviews genomic and proteomic studies of VPAHPND isolates from different countries. The paper further presents the need for a global cooperative emergency response network for disease outbreaks.
Tolerance of lumpfish, Cyclopterus lumpus, to freshwater bath treatment for amoebic gill disease, Neoparamoeba perurans, infection and efficacy of different treatment regimens
Treasurer, J. and T. Turnbull.
Amoebic gill disease is a major problem for the cleaner fish species most frequently used in salmon farming, the wrasse species and lumpfish, for control of sea lice. Treasurer and Turnbull (2019) report results of studies on the use of freshwater bath treatments for amoebic gill disease. High efficacy of reducing amoebic numbers was achieved with: 5-hour treatment at 0 ppt salinity; 3-hour treatment of 0, 3, 0r 5 ppt salinity; and 3-day treatment at 15 ppt.
Dietary protein requirement for juvenile mandarin fish, Siniperca scherzeri
Sankian, Z., S. Khosravi, Y-O Kim, and S-M Lee
Mandarin fish, Siniperca scherzeri, is a highly-valued fish in China, but decreased wild landings have created market shortages. Farmed mandarin fish are primarily fed live fish of other species, and formulated feeds are not available for mandarin fish. Sankian et al. (2019) investigated the dietary protein level of juvenile mandarin fish, finding that juvenile mandarin fish need a relatively high level of crude protein (614 g/kg) in their diets.
About World Aquaculture Society
The World Aquaculture Society was founded in 1969 as the World Mariculture Society. Since it’s beginning the membership in WAS has grown to more than 3,000 members in about 100 countries representing the global aquaculture community. In order to meet the expanding international nature of the Society and to address specific needs in various areas of the world, the WAS has created Chapters in the United States, Japan, Korea, Latin American and Caribbean region, Asian-Pacific region and most recently in Africa.
