This study aimed to identify the causative of the mass mortality observed in zoeal to post-larval shrimp raised in hatcheries in south Iran. For three consecutive months, samples of nauplii and zoea of Litopenaeus vannamei were collected from an affected hatchery located in the province of Bushehr. Upon culture on marine agar, bacterial colonies that produced white, orange, yellow and red pigme...

Viral pathogens appear to exert the most significant constraints on the growth and survival of crustaceans under culture conditions. The prevalence of viral pathogens White Spot Syndrome Virus (WSSV), Hepatopancreatic Parvo Virus (HPV), Monodon Baculo Virus (MBV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) in Penaeus monodon post-larvae was studied. Samples collected from ...

During the period from August 1997 to March 1998, two thousand samples of cultured Penaeus semisulcatus postlarvae and subadults were collected from five hatcheries and 20 growout farms distributed in three provinces along the costs of Persian Gulf and the Oman Sea. Based on growth signs, LM and TEM histopathology, Hepatopancreatic Parvo-like Virus (HPV) were identified from the samples. The HP...

Fish seed as a primary input determines the pace of aquaculture development. Traditionally, fish was sourced from natural water bodies, and farmers faced several constraints like mixed ununiformed non-targeted species, uncertain supplies. The development induced breeding technologies enabled establishment large numbers hatcheries. Since then, remarkable growth has taken place in production. Yet...
