When it comes to chilling fish, there’s a lot of tradition and a lot of guesswork. But a new scientific study out of Iceland cuts through the noise with hard data.

In a tightly controlled trial, researchers at Matís compared fish cooled in an older RSW system with those chilled using modern slurry ice.

Same vessel. Same species. Same processing. Just different chilling methods.

Here’s what the numbers showed:

Side-byside comparaison of slurry ice and RSW cooling, in terms of cooling speed, water loss, shelf life, sensory score and auction value
Slurry ice technology delivers faster and more. uniform chilling, reduced drip loss, longer shelf life, and higher product value compared to traditional RSW systems.

What’s the Cost of Doing Nothing?

  • More downgraded or rejected fish
  • Shorter shipping and sales window
  • Less leverage with premium buyers
  • Lost margins due to quality inconsistency

If you’re running an older RSW system, and many vessels in Alaska still are, these numbers are a wake-up call.

Rethink Your Onboard Setup

Modern chilling systems aren’t just about bells and whistles. They’re about data-backed performance that improves:

  • Profitability
  • Shelf life
  • Cold chain efficiency
  • Your long-term competitiveness

At KAPP, we’ve helped vessels in Alaska and Iceland move from tradition to transformation by upgrading their chill and watching the value follow.
