Proximar Seafood AS is employing an automated, water-bourn feeding system from Graintec at the aquaculture company’s soon-to-be completed land-based salmon farm at the foot of Mt. Fuji, Japan.

The recirculating aquaculture system (RAS) facility in Oyama which is expected to produce 5,300 tons of salmon annually, will be using Graintec’s HyFlow feeding system which is designed to provide minimum environmental footprint for both land-based and off-shore fish farming applications. The system also is capable of underwater and/or on-surface feeding using pellets from two to 18 mm. The feeding system also provides a  feed storage that is designed to create a minimum of physical impact on the costly feed pellets.

The system is easy to install and maintain as it consists of very few moving parts. The system is fully automatic with a SCADA-based open source software solution that easily integrates other farm management software.

The system is appropriate for Proximar’s large-volume feeding needs, according to Lars Stigaard, chief technology officer for Proximar’s operations in Japan.

“First of all the HyFlow system has low complexity, easy to operate and easy to maintain, and is very gentle to the feed pellets,” Stigaard said. “For us, having a minimum of feed loss and a water-borne solution ensures practically zero breakage, even when feeding large diameter pellets. We can feed in different debts in the fish tanks, ensuring a good feed distribution in the full tank volume.”

In January this year Proximar’s first batch of juvenileb Atlantic salmon were successfully transferred to the start feeding department and have started to take feed. This marks a breakthrough for Proximar’s production team, after the first eggs were successfully inserted in the company’s Oyama hatchery in October 2022.
