Tuna feed for the future

Now available in Japan, MaGro is a soft extruded feed for bluefin tuna created using patented production technology to ensure high palatability for the fish. MaGro is our soft extruded pellet, and unique in Skretting. The pellet can be squashed, without breaking. Due to this unique soft texture tuna easily accept the diet.

The high nutrient density in MaGro means that the feed conversion ratio (FCR) is about 1/3 what is achieved when feeding baitfish. The formulation is also very consistent, comprising fully-traceable ingredients, whereas the nutritional profile of baitfish can fluctuate dramatically depending on the species used, when and where it was caught, and the storage system Baitfish also needs to be frozen. The practical, easy-to-use format of MaGro means that farmers can utilise semi-automatic “canon” feeding systems, supporting much more efficient, cost-effective production, while also reducing water pollution compared to traditional baitfish feeding.

Growth performance with MaGro is similar to the one achievable with baitfish during summer conditions, and higher during winter conditions. This makes MaGro a cost-effective way to feed your tuna.
