SPF Shrimp Feeds to distribute live SPF polychaetes to India
January 5, 2021

SPF Shrimp Feeds, a company co-founded by Stephen Christensen and Florian Renault, specializes in live, fresh and natural specific pathogen-free feeds for shrimp hatcheries. For the last 18 months, SPF Shrimp Feeds has worked closely with Topsy Bait (The Netherlands) to perfect the packaging, transportation and in-country storage system that allows live polychaetes to be shipped anywhere in the world and kept alive in-country for daily delivery to shrimp hatcheries. 


Prior to coming to market, the two companies worked closely on a three-month trial that fed Topsy Bait’s live SPF polychaetes to shrimp broodstock, benchmarked against local, wild-caught polychaetes common to Asia, as well as frozen polychaetes. Additional laboratory testing revealed cold-water origin polychaetes have a far superior nutritional profile than tropical worms.


Nereis virens polychaete profile is: Protein: 13.49 g/100g; Hydrolyzed fat: 2.06 g/100g; Moisture: 81.40 g/100g; DHA: 23 mg/100g; EPA: 135.1 mg/100g; Total fatty acids: 1547.1 mg/100g. “The biosecurity benefits cannot be understated: 100% farmed in a completely bio-secure environment done according to GMP+ and HACCP standards with certifications. The OIE (World Organization For Animal Health) recognizes The Netherlands as an aquaculture disease-free country, and further government testing prior to export guarantees the polychaetes to be free of EHP, DIV1 and AHPND,” the company said.


Live SPF Polychaetes as a shrimp broodstock feed increases the nauplii number per female, increases the mating and maturation rate, offers better recovery after each spawning, increases the quality of the sperms and eggs (higher hatching rate) and offers full traceability from worms to the final shrimp PLs. These conclusions are substantiated by data collected over 18 months of sales and customer trials.


“India’s Coastal Aquaculture Authority deserves praise for its role in approving the first-ever import license for live polychaetes, a monumental moment for India’s shrimp aquaculture industry,” the company said.


SPF Shrimp Feeds is the exclusive distributor of Topsy Bait’s Live SPF Polychaetes in Vietnam and India. Topsy Bait also sells SPF polychaetes under the Delta Farms brand, making it the world’s biggest and only commercial-scale SPF polychaete (Nereis virens) farm.
