Skretting’s new marine broodstock diet responding to hatchery needs

Wednesday, November 4, 2020

Skretting will globally introduce Vitalis PRIMA in the coming months, a new marine broodstock diet that supports the health of parent fish and young fry, thereby improving the performance of hatchery systems.

Vitalis PRIMA, which will replace Vitalis CAL, incorporates some of the latest technology from ground-breaking dietary research as well as commercial input from broodstock and hatchery managers. It is the latest solution to come from over 25 years of broodstock feed development at Skretting.

Using internal expertise, trials and collaborative studies, Skretting optimized the latest diet for several marine species, including seabass, sea bream, halibut, amberjack, turbot and cobia. At the same time, the development opened up discussions with many broodstock and hatchery managers about what additional attributes they would like to see in a marine broodstock diet.

“As well as seeing increased fry survival through improved embryo vitality, hatcheries wanted diets that were much more compliant with the recirculation systems that they use, they also asked for the feed to be much more appealing to broodstock that can often stop feeding during the spawning window,” said Eamonn O’Brien, Skretting product manager.

Five key attributes have been included in Vitalis PRIMA:

  • Increased fry survival through improved embryo vitality.
  • Suitability for recirculating aquaculture systems (RAS).
  • Increased appeal for broodstock when feeding slows during spawning.
  • Improved appearance of broodstock through the addition of marine algae blend.
  • Inclusion of algal oil for sustainability and stability.

Vitalis PRIMA is also closely aligned with Skretting’s other Vitalis diets: Vitalis Clean for lumpfish broodstock, Vitalis 2.5 for shrimp and Vitalis Repro which is offered to marine fish outside of the spawning window to maintain their optimal spawning condition.

“Vitalis PRIMA, together with Vitalis Repro, will provide a complete feeding program for broodstock fish and make a considerable contribution to Skretting’s standing as the market leader in the field of broodstock nutrition. We are very excited about the long-term benefits that this will bring for farmers of marine species throughout the world,” said Julio Docando-Valencia, Fish Health Diets manager at Skretting South Europe.
