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...
