Post-smolt & Full-cycle Grow-out

Eco Model R is designed for the optimal production of post-smolts or grow-out to harvest size. The high water exchange with a controlled, rotating water flow provides the perfect conditions for high stocking densities at all fish sizes.

*In January 2022 Ecomerden became a part of the FiiZK Group.
