Tunicate meal tested for feed pellet quality

When developing a new ingredient for use in fish feed, there is many parameters that needs to be scrutinized. And tunicate meal are no exception. During the last three years Marine Feed has tested the feed in three larger projects and more test are under process or evaluation.

A recent post from the industry newspaper Fish Farming Expert interview the expert Tor Andreas Samuelsen from the Norwegian research institute NOFIMA. Their work focus on different quality paratmeters of the feed pellet during and after process in an extruder.

One of the results was that feed pellets with a large percentage of tunicate meal had large pores and they also found that 50 % of the fish meal in standard feed can be replaced with tunicate meal without compromising the quality of the feed.
