The virucidal effect of pH and salinity on Penaeus monodon baculovirus (MBV) was investigated by water borne inoculated methods exposing PL12 Penaeus semisulcatus for 10 hours and observing for 10 days at temperature 28- 30°C. For this purpose, one thousand virus free PL12 of P. semisulcatus were divided into five groups and each group placed in a 10 L plastic basin containing chlorine-treated ...

The survival rate of Penaeus monodon was monitored for a decade (2010-2019) in two shrimp culture ponds at Chemaguri located Sagar Island the Indian Sundarbans delta complex. exhibited significant variations terms cultured species, which is attributed to nitrate, phosphate, and dissolved oxygen. root cause such difference related variation stocking density species (10 PL20/m2 pond 1 25 2) resul...

To salvage marine ecosystems from fishery overexploitation, sustainable and efficient aquaculture must be emphasized. The knowledge obtained available genome sequence of organisms has accelerated in many cases. black tiger shrimp (Penaeus monodon) is one the most prominent cultured penaeid shrimps (Crustacean) with an average annual global production half a million tons last decade. However, it...

Shrimp aquaculture has a short history in I.R Iran. Farmed shrimp production grew slowly from 1992 until 2000 when a number of large farms started to produce. In 2000, the total production was about 4,500 MT and it was estimated that more than 7,000 MT would be produce by the year 2001. From August 1997 to March 1998, two thousand samples of cultured Penaeus semisulcatus postlarvae and subadult...

Gill-associated virus (GAV) is a nidovirus that commonly infects Penaeus monodon (black tiger shrimp) in eastern Australia, causing morbidity and mortalities in the acute stage of disease. Here we explored the possibility of inhibiting GAV replication and disease using double-stranded (ds)RNAs expressed in bacteria and delivered either orally or by muscle injection. To enhance potential RNA int...

A highly sensitive test based on reverse transcription followed by nested polymerase chain reaction (RT-nPCR) was developed to detect the Australian yellow-head-like viruses, gill-associated virus (GAV) and lymphoid organ virus (LOV) of Penaeus monodon. The RT-nPCR detected viral RNA in as little as 10 fg lymphoid organ total RNA isolated from GAV-infected P. monodon. Amplification of serial di...
