[Annelida] SPF polychaetes

[Gordon Bock]

Hello everybody,

Does anyone know about polychaetes being a vector for diseases? I know about the White Spot Syndrome Virus (WSSV) that can be transmitted onto shrimp (Vijayan et al. 2009). Are there any other crustaceans, molluscs or finfish that can be infected through polychaetes?
For the aquaculture industry it is important that the broodstock nutrition has a specific pathogen free status (SPF). It defines that organisms within the feed should be free of pathogens including viruses, bacteria and parasites. I would further like to know that if the feed contains polychaetes which tests are routinely being conducted to proove this status (SPF)?

I would be thankful for any information, advice or even scientific abstracts on the subject.
You can also send me an email to gordonbock from web.de.

Have a nice day, 

Gordon Bock
