Harvested in the extreme northern parts of China near the Russian border, Gulf Breeze Marine Polychaetes have the highest levels of protein, DHA, EPA and vitamin C than any other commercially available marine polychaete.  Our Marine Polychaetes are tested via PCR testing for shrimp viruses at least three times before reaching the end user - and in over 5 years never has there been a positive result.  One of such tests is done by the University of Arizona Shrimp Pathology departement.
