Monitoring and identification of viral pathogens in SPF(Specific Pathogen Free) shrimp production project
Shrimp aquaculture has developed rapidly in 1980s decade and this development caused to increase ahrimp diseases in farms. In the last 0f 1980s and first of 1990s find of health shrimp Postlarvae for stocking was hard. In Iran also after two decades diseases are the main problems, then a national project (Shrimp SPF production)was performed that this section was monitoring and identification of viral pathogens in that project. For this propose selected shrimps in farms was sampled and screened for main viruses (OIE list), shrimps without infection bring to quarantine system for one month and in the end of quarantine period were screened again. Then in winter spending, before and after spowning, it’s offspring in F1 and F2 also screened for viral pathogens by IQ2000 kit in Iranian veterinary organization lab. Moreover all shrimp feeds in clouding: fresh feed, live feed and pellet feed had been screened for OIE viral pathogens listed for three years. Results of viruses screening in shrimp sampled in all stages of project and feed that use in this project were negative. This project (SPF shrimp production in IRAN) performed successfully, we think this success relate to biosecurity system that were influence in this project.

| Summary: | Shrimp aquaculture has developed rapidly in 1980s decade and this development caused to increase ahrimp
diseases in farms. In the last 0f 1980s and first of 1990s find of health shrimp Postlarvae for stocking was hard.
In Iran also after two decades diseases are the main problems, then a national project (Shrimp SPF
production)was performed that this section was monitoring and identification of viral pathogens in that project.
For this propose selected shrimps in farms was sampled and screened for main viruses (OIE list), shrimps
without infection bring to quarantine system for one month and in the end of quarantine period were screened
again. Then in winter spending, before and after spowning, it’s offspring in F1 and F2 also screened for viral
pathogens by IQ2000 kit in Iranian veterinary organization lab. Moreover all shrimp feeds in clouding: fresh
feed, live feed and pellet feed had been screened for OIE viral pathogens listed for three years. Results of viruses
screening in shrimp sampled in all stages of project and feed that use in this project were negative. This project
(SPF shrimp production in IRAN) performed successfully, we think this success relate to biosecurity system that
were influence in this project. |
