Holding of Arctic char in a RAS transport system
In September 2019 two live holding trials with Arctic char ( Salvelinus alpinus ) were carried out at Matís where the fish was kept for up to eight days in a RAS holding and transport system developed by Technion, Israel Institute of Technology. The RAS system, which recirculated the water, controle...

In September 2019 two live holding trials with Arctic char ( Salvelinus alpinus ) were carried out at Matís where the fish was kept for up to eight days in a RAS holding and transport system developed by Technion, Israel Institute of Technology. The RAS system, which recirculated the water, controled the pH and removed accumulated ammonia, was set up in a 40 feet reefer tank to control the temperature at 4°C. The project was funded by EIT food and the participants were Technion and Matís.
