TOPSY BAITS

Marine Bloodworms are the most essential component of the maturation diet for all Penaeid shrimp broodstock. These marine bloodworms (Nireisvirens) are cultured by Topsy Baits in bio-secure, land-based ponds along the European coast of the North Sea. The cold-water temperatures and marine algae diet produce a bloodworm high in essential fatty acids (HUFA’s), necessary for sustained reproduction of shrimp broodstock.

Proaqua sources the bloodworms from Topsy Baits, the largest supplier of farmed live bait in Europe. Click here to visit the Topsy Baits website.

    Frozen SPF Polychaetes

    Marine polychaetes have been proven to be crucial for the sexual maturation and reproduction of fish and shrimp. N.virens contains high levels of digestible protein and are essential for the production of eggs in shrimp. Topsy is located in the temperate zone of Europe, thousands of kilometers away from all known shrimp diseases. Each batch is tested for shrimp pathogens by the University of Arizona. All tests have been negative ever since Topsy started supplying shrimp hatcheries.
