Abstract

Luminous vibriosis and the sources/routes through which it entered the tiger shrimp (Penaeus monodon) hatchery near Visakhapatnam was studied during June 2006 - February 2007. Five larval cycles of Penaeus monodon were examined. Vibrio harveyi was present in all the luminous vibriosis samples. The natural seawater, the "carrier" brooder shrimps, the ineffective sterilization methods and unhygienic handling practices were found to be the major sources of luminous vibriosis in sterile shrimp hatchery facilities.
