Aquaculture in the Philippines: The Top 10 Diseases Shrimp Farmers Should Be Aware Of
Shrimp are one of the most popular aquaculture species in the Philippines. Shrimp farming can be highly profitable, with higher harvest rates and relatively low production costs compared to other species when standardized, sustainable aquaculture approaches are followed. Disease outbreaks over the last two decades, however, have led to dramatic declines in the shrimp output and challenges for ...

U.S. Aquaculture Gets Bipartisan Boost from Washington
Good news has been hard to come by the last few months amid the COVID-19 pandemic, but the United States aquaculture industry received some two weeks ago. On May 7 the White House issued an executive order aimed at “removing outdated and unnecessarily burdensome regulations” that have long hampered aquaculture efforts in the U.S. The executive order comes just two months after the ...

Enhanced resistance to BCWD in Troutlodge strains
Joint research of the United States Department of Agriculture (USDA) and Troutlodge has shown that Genomic Selection can double the prediction accuracy for Bacterial Cold Water Disease (BCWD). Application of Genomic Selection for BCWD resistance to three generations of Troutlodge broodstock resulted in a challenge survival increasing from 33.5% in 2015 to 78.3% in 2019. This is a staggering ...

Affetcs of Yellow Head Virus (YHV)
Yellow Head Virus (YHV) Yellow Head Virus was the first major viral disease problem to affect Asian shrimp farms when it was diagnosed as causing extensive losses for shrimp farming. YHV and its close relatives GAV and LOVV are single stand RNA viruses, similar to TSV. The first records of this virus were from P. monodon ponds in Eastern Thailand, it had moved to Southern Thailand and was ...

Affects of White Spot Syndrome Virus (WSSV) in Shrimp Farming (Part 3)
White Spot Syndrome Virus (WSSV) is now and has for some time been the most serious threat facing the shrimp farming industry in Asia. It is an extremely virulent pathogen with a large number of host species. This disease is probably the major cause of direct losses of shrimp farming in Asia. Similarly, in Latin America, losses due to WSSV have been substantial. In addition, indirect losses in ...

Affects of Viral Disease in Shrimp Farming
In Shrimp Disease control, they are Six viruses were known to affect Penaeid shrimp, but there are more than 20 viruses were identified as having affected wild stocks and commercial production. The OIE now lists seven viral diseases of shrimp in the Aquatic Animal Health Code, which are considered to be transmissible and of significant socio-economic and/or public health importance. These ...

Bacterial disease of Shrimp
Rickettsial Infections This infection is not recorded yet from Indian waters, systemic rickettsial infections were reported from cultured P. monodon from Malaysia and Singapore. In P. monodon, the rickettsia occurred within large cytoplasmic vacuoles where it formed-microcolonies of 19 to 33 f.lm in diameter. In heavy infections, cells with rickettsial inclusions were widespread in mesodermally ...

Monitoring Ozone (in the air) in Hatchery & Fish Farm Ozone Injection Systems
Hatcheries, fish farms and such in the aquaculture industry require clean water to maintain a high survival rate while rearing aquatic animals. Contaminated water increases the risk of infection which in turn can compromise production. A common way to disinfect water is by generating ozone on-site with an ozone generator, which is commonly inside an ozone generator room. For human safety, the ...

Modeling fish production for Southern California's petroleum platforms
California's oil platforms are nearing the end of their productive lives, and therefore will be decommissioned in the near future. These structures have been shown to be important habitat for both settlement and growth for reef fishes. Important information on the biological effects (i.e. loss of biomass and production) of different decommissioning options has not yet been explored in detail. ...

Nechako White Sturgeon Conservation Centre - Case Study
The Freshwater Fisheries Society of BC developed the Nechako White Sturgeon Conservation Centre to try to prevent extinction of this endangered species. Wild caught brood fish are held in the facility until spawning is complete. Controlled family groupings of young sturgeon are hatched in McDonald jars and reared for one year, first in 0.5 m3 and 1.5m3 combi tanks, then 8 m3 tanks before release. ...

Embryonic exposure to 2,3,7,8‐TCDD impairs prey capture by zebrafish larvae
2,3,7,8‐TCDD remains a ubiquitous, persistent environmental contaminant with the potential for causing lethal deformities in larval fishes. Few studies have examined its impacts on larval growth and craniofacial development in conjunction with feeding capability. Here we use morphological and behavioral assessments to demonstrate that feeding capability of larvae is impaired even when ...

AHPN inferences based on behavior of Vibrio bacteria
Summary: Vibrio parahaemolyticus, the pathogen associated with acute hepatopancreatic necrosis (AHPN), has both toxic and benign strains. It inhabits the stomachs of shrimp in a biofilm, which protects it from antibiotics and other treatments. As with V. cholera, V. parahaemolyticus tolerates a range of salinities, pH and temperatures. Both species readily piggyback on marine plankton and may be ...
