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 increased occurrence of devastating viral diseases in shrimp culture systems threatens the sustainability of both the aquaculture industry and the commercial shrimp fishery. HPV is associated with reduced growth rates of juvenile shrimp without showing any gross signs of disease and can lead to mass mortalities in shrimp populations. [ 21 ]
Arthropods, especially detritivores in the Order Isopoda, Suborder Oniscidea (), have been shown to be able to store heavy metals in their hepatopancreas. [3] This could lead to bioaccumulation through the food chain and implications for food web destruction, if the accumulation gets high enough in polluted areas; for example, high metal concentrations are seen in spiders of the genus Dysdera ...
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
Mantis shrimp typically grow to around 10 cm (3.9 in) in length, while a few can reach up to 38 cm (15 in). [7] A mantis shrimp's carapace covers only the rear part of the head and the first four segments of the thorax. Mantis shrimp widely range in colour, with species mostly being shades of brown to having multiple contrasting, vivid colours.
Japanese kourayaki, or blended crab tomalley and roe baked in its shell. Tomalley is the hepatopancreas (the organ that fulfills the functions of both the liver and the pancreas) of a lobster, crab or other arthropods) of a crustacean when used for culinary purposes.
Mysida is an order of small, shrimp-like crustaceans in the malacostracan superorder Peracarida. Their common name opossum shrimps stems from the presence of a brood pouch or "marsupium" in females. The fact that the larvae are reared in this pouch and are not free-swimming characterises the order. The mysid's head bears a pair of stalked eyes ...
The absence of pancreatic body and tail is the usual manifestation of dorsal pancreatic agenesis, the density and morphological features of the pancreatic head should be either normal or slightly enlarged due to compensation of the absent body and tail. [4] Stomach/intestine sign can combine with CT for better diagnosis.
