Yellow Headed Syndrome Virus (Shrimp)

This disease caused by the yellow headed virus(YHV) a positive sense single stranded RNA virus related to coronavirus and arteriviruses. A closely related virus is the gill-associated virus(GAV),which is the type species of the genes okavirus.

YHSV leads to death after 2-4 days, YHSV is a viral infection of shrimp and prawn

HISTORY:- First detected in 1990 Thailand and in Australia 1995 in formed fields and spread through out the World.









This disease is named because of change in the appearance of hepto pancreas from brown to yellow.



  1. Treatment consists of binding to the -COOH end of the single strand RNA. Genetic silencing to Next generation.

  2. Already existing reproductive protein denaturation.

  3. Observed change of color within 8 Hrs from yellow to brown.


YHSV Caused to both shrimps and prawn:-


Crustaceans may have several common names but only one common name is provided in this list. Note: the terms "shrimp" and "prawn" can both be used.


  • Euphausia superba (Antarctic krill)

  • Exopalaemon styliferus (roshma prawn)

  • Farfantepenaeus aztecus (brown shrimp)

  • Farfantepenaeus duorarum (spotted pink shrimp)

  • Fenneropenaeus merguiensis (banana prawn)

  • Litopenaeus setiferus (northern white shrimp)

  • Litopenaeus stylirostris (blue shrimp)

  • Litopenaeus vannamei (whiteleg shrimp)

  • Macrobrachium sintangense (Sunda River prawn)

  • Marsupenaeus japonicus (kuruma prawn)

  • Metapenaeus affinis (jinga shrimp)

  • Metapenaeus bennettae (greentail prawn)

  • Metapenaeus brevicornis (yellow prawn)

  • Metapenaeus ensis (greasyback prawn)

  • Palaemon serrifer (barred estuarine shrimp)

  • Penaeus esculentus (brown tiger prawn)

  • Penaeus monodon (giant tiger prawn)

  • Yellow head  disease is a RNA  based viral disease  related to coronaviruses and arteriviruses which occurs in species like Penaeus monodon (giant tiger prawn).

  • YHD is a highly lethal, and contagious, killing shrimp quickly.

  • This disease is caused by  Yellow head virus(YHV).

  • Prevention/Treatment: New molecule is invented which prevents/cure by virucidal and virustatic activities.

  • The spread of the disease is controlled by Virustatic and virucidal activities performed by the same molecule.

  • This molecule can be administered as aqua feed supplement .

  • For Each viral cycle terms wise doses can be administered to prevent YHD in shrimp culture .

  • This leads to stress relieving to the shrimp where YHD is a stress related disease.

  • We have screened 900 new molecules and selected 1 molecule among them to prevent and control YHD.

  • Prevention consists of treating each viral cycle,  we are treating the shrimp to free from YHV and whenever shrimp is effected with YHV.

  • The Dosage can be customized to suit specific pond/area/country salinities
