Nereis  virens
Our SPF Live Polychaetes from TOPSY BAITS & DELTA FARMS of (Nereis virens species) are 100% farmed in a completely bio-secure environment done according to GMP+ and HACCP standards (with certifications). Prior to export, the Polychaetes are tested by various private and government accredited labs validating both the nutrition and bio-security profiles. The nutritional quality is stable throughout the year as worms are fed by special pellets formulated and produced in Europe. Farming Polychaetes in cold waters results in high HUFA levels, 4-5 times more compared to tropical worms. The farming output is more than 300 tons per year, which offers a much more stable supply compared to wild caught, contaminated worms commonly supplied in Asia. Live Polychaetes as a shrimp broodstock feed will increase the nauplii number per female, increase the mating rate, increase the maturation rate, offer better recovery after

each spawning: increase the quality of the sperms; increase the quality of the eggs (higher hatching rate); and offer full traceability from the worms to the final shrimp PL.

*Wet analysis performed by Upscience Laboratory in Vietnam.

Total fatty acids:  1547mg/100g.

Packaging
The polychaetes are packed in trays with 365g of polychaetes, minimal water, and oxygen before being sealed. 10 trays per box; with ice for temperature management.
Sizing
In general, there are 500 individual worms per one kilogram of weight. Sizing will vary depending on the time of year, but the lenghth will range from 6-15cm.

Instructions for use
Calculate 15-20% of the total biomass of the breeders, and the polychaetes should represent 37.5% of total feed given to the breeders, per day.
Storage
Polychaetes should be kept in seawater with aeration at a constant temperature of 10-15°C, 2.5kg biomass to 20L of seawater until used for feeding. Daily water exchange of 100% is required for optimal survival rate.
