The University of Tartu has initiated a project to set up a beach oyster farm in Haapsalu Bay, one of the most polluted coastal waters in Estonia due to an abundance of nutrients. The proposed oyster farm is expected to utilize the natural food resources to help the oysters grow, which in turn will help improve the water quality and mitigate eutrophication in the bay.

The facility will be specifically designed to withstand the environmental conditions of the Baltic Sea, including low salinity and risks of ice and storms during certain seasons. The oyster farm will consist of 20 main lines, each measuring 200 meters, with cultivation ropes tailored to the specific oyster species, Mytilus edulis and its hybrids. This meticulously planned infrastructure aims to remain stable even during rough seas, reinforcing the importance of the farm in restoring the bay's ecology.

In the winter months, the installations will be submerged to protect them from ice damage, with markers such as buoys indicating their presence. This project not only seeks to revitalize the local marine ecosystem but also to set a precedent for future bio-restoration efforts in similar affected areas of the Baltic region.
