Early in the morning, a research vessel was spotted on the Pärnu River, carrying a team of three individuals. Near the mouth of the Reiu River, the team successfully hooked and retrieved a net from the water. The scientists, who are affiliated with the Tartu University Marine Institute, managed to pull the net—which contained latches and haugs—out of the river using the boat’s cranes.

Crucially, the team ensured that all marine life caught within the net was safely returned to the water. The primary reason for the operation is linked to ongoing scientific research. The teadurid are conducting a study focused specifically on the movement patterns of this type of net (koha) within the Pärnu River ecosystem.

This effort underscores the institute’s commitment to monitoring and understanding local aquatic environments. Visual documentation of the event, available in the accompanying video, shows the careful process of recovery. The team worked systematically to secure the equipment without causing undue disturbance to the riverbed or the surrounding fauna.

The recovery of the koha itself is central to the data collection, as its retrieval allows researchers to analyze its interaction with currents and biological activity. The operation highlights the blend of fieldwork and academic study taking place on the river. The careful handling of the equipment and the subsequent release of marine life demonstrate a methodical approach to environmental data gathering.

This initiative provides valuable insights into river ecology and serves as a case study for understanding dynamic changes within the Pärnu River system.
