The project they are delivering RAS production equipment to is called ReCod, and will produce cod larvae for release in the wild in Baltic sea. The facility will be build in connection with the research station Ar in Gotland, and the project is carried out by the foundation BalticWaters2030 in cooperation with, among others Uppsala university, and Sweden’s sport fishing- and fisheries conservation association.

Facts about BALTIC WATERS 2030

The foundation BALTIC WATERS 2030 aims to improve the environment in Baltic sea, which has been impacted by pollution and over fishing.

The cod stock in Baltic sea is today characterized as in crisis. For the stock to improve, it will be necessary with multiple measures. We hope that release of cod will have a positive impact. In the project “ReCod – release of small cod in Baltic sea” we want to test if it is possible to strengthen the cod stock by helping the cod through the vulnerable egg stage, and release the fish in the larval stage. If the measures succeed, it will become a template for future release support.

The demonstration project is carried out at the research station Ar in Gotland, in the middle of the Baltic sea. Cod from the eastern fish stocks in the Baltic sea must be captured continuous before reproducing through natural spawning at the research station. After hatchery, the 5 – 6 days old cod larvae will be released in selected areas in the Baltic sea.

The project estimate to breed and release 1 – 1.5 million cod larvae each year.

Trial fishing and scientifically based sampling is performed continuously for close follow up on the project results.
