Penaeus

Abstract: There are five different viruses which are currently being studied for their impact on commercial farming of the black tiger prawn (Penaeus monodon) in Thailand. Some of these viruses cause disease in other penaeid shrimp species and even other crustacean species. Some occur not only in cultivated shrimp in other Asian countries, but also in those from Australia and the western hemisphere. In descending order from greatest to least economic impact on the Thai shrimp industry, the five viruses are: white-spot baculovirus, yellow-head virus, hepatopancreatic parvo-like virus, infectious hypodermal and hematopoeitic necrosis virus and monodon baculovirus. The purpose of this review is to summarize recent work on these viruses and to suggest future directions of research that may be useful in the effort to develop a sustainable shrimp industry.

Abstract: The growth and survival of Penaeus vannamei postlarvae was measured at temperatures of 20, 25, 30 and 35 °C and salinities of 20, 30, 35, 40 and 50%.. Groups of 30 animals were used in each combination of conditions, in triplicate. The results clearly show that juveniles of this species have their best survival between temperatures of 20 and 30 °C and salinities above 20%.. Best growth was obtained between temperatures of 25 and 35 °C, with little difference being noted among salinities. Survival and growth coincide best at around 28 to 30 °C and 33 to 40%.. Calculated overall production was shown to be best in these conditions. The results demonstrate a high coincidence between the experimentally determined optimum conditions for production and the prevailing conditions in the coastal environment from which the animals originated.

Abstract: Shrimp, a major seafood allergen, was investigated as a model food allergen. Extracts from both shrimp ( Penaeus aztecus ) meat and cooking fluid contain a substantial and similar amo
