Fish feed company Skretting is rolling out a broodstock diet that is meant to be compatible with recirculating aquaculture system (RAS) environments.

The company said its Vitalis PRIMA product is a new marine broodstock diet from Skretting that supports the health of parent fish and young fry.

The product is also aimed at hatcheries using RAS, according to a press release from Skretting.


“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, product manager at Skretting.

Five key attributes have been included in Vitalis PRIMA:

  • Optimised nutritional formulation for broodstock
  • Consistent high quality and palatability
  • Improved compatibility with RAS
  • Enhanced health and robustness
  • Improved biosecurity and sustainability eliminating the need for fresh feed supplementation

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 market leader in the field of broodstock nutrition,” said  Julio Docando-Valencia, fish health diets manager at Skretting South Europe.”We are very excited about the long-term benefits that this will bring for farmers of marine species throughout the world.”
