Necrotising hepatopancreatitis (NHP), is also known as Texas necrotizing hepatopancreatitis (TNHP), Texas pond mortality syndrome (TPMS) and Peru necrotizing hepatopancreatitis (PNHP), [1] is a lethal epizootic disease of farmed shrimp. It is not very well researched yet, but generally assumed to be caused by a bacterial infection.
The shrimp-farming industry has developed several broodstocks of both P. stylirostris and P. vannamei that are resistant against IHHN infection. [1] The disease is caused by a single-stranded DNA virus of the species Decapod pestylhamaparvovirus 1, earlier known as IHHN virus, the smallest of the known penaeid shrimp viruses (22 nm). [2]
Taura syndrome (TS) is one of the more devastating diseases affecting the shrimp farming industry worldwide. It was first described in Ecuador during the summer of 1992. In March 1993, it returned as a major epidemic and was the object of extensive media coverage.
These signs were accompanied by mortalities, which reached up to 50-100% of an affected population of P. merguiensis within 4-8 weeks of disease onset. [1] [13] Soon after, cultured populations of four shrimp species from four separate culture facilities in Asia were found to be adversely affected by a disease of presumed viral etiology. [13]
A new study in the journal Frontiers in Toxicology found that microplastics in the fish we consume are far more widespread than you may think.. In late December, researchers from Portland State ...
PSP affects those who come into contact with the affected shellfish by ingestion. [1] The toxins responsible for most shellfish poisonings—mainly saxitoxin, although several other toxins have been found, such as neosaxitoxin and gonyautoxins I to IV—are water-insoluble, and heat- and acid-stable.
Getty Images In August, as the price of shrimp soared to $5.80 a pound, CNN called the new price on headless crustaceans an "all-time high." But do you know what consumers today would call that price?
White spot syndrome (WSS) is a viral infection of penaeid shrimp.The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world.
