Unfortunately, we have witnessed a sharp decline of Atlantic cod (Gadus morhua) in Swedish waters since the 1980s, especially coastally. One possible strategy to overcome natural mortality could be to bring in small fish, let them grow in a protected environment, and then release them back into the wild. This is something that the public aquaria Havets Hus in Lysekil, Sweden, has started to look into. By using acoustic telemetry, we aim to track the released cods along the Swedish west coast to better understand the behaviour and survival. The Department of Wildlife, Fish, and Environmental Studies at the Swedish University of Agricultural Sciences manages this work.
