TIVA UVC IN ÖLAND'S PIKE WETLANDS
Along the coast of Öland, several wetlands have been restored and reconstructed to benefit the pike. The purpose is to strengthen the pike populations in the Baltic Sea, which have declined sharply in recent decades. The pike on Öland are also genetically unique and isolated from the mainland populations, which makes their conservation particularly important.
To measure the effect of these wetlands, reliable data is needed to show that the pike are actually using them. Traditional methods such as traps are often resource-intensive and add stress to the fish, which must be handled manually.
SOLAR POWERED PIKE MONITORING
TIVA was commissioned to deliver a solution that could provide continuous and reliable monitoring, and TIVA UVC underwater cameras were placed with bottom stands in several locations on Öland. As the locations did not always have access to a fixed power supply, solar panels were installed to run the systems.
Like our other systems, the video stream here has been analyzed in real-time by our AI algorithm, which automatically registered every passing fish. The results, including video clips of each individual, are sent directly to the platform fiskdata.se where they can be followed by project managers and administrators in real-time.
CONCRETE RESULTS WITH TiVA’S SYSTEM
With the new solution, the monitoring of the pike wetlands took a big step forward. Instead of random samples, TIVA UVC provides a more comprehensive and continuous basis for the pike’s spawning migration. The detailed time data also makes it possible to link the migration to environmental factors such as temperature and water flow.
With the help of TIVA UVC, the pike factories can now show concrete results with data for future decision-making and at the same time gain new insights into the pike’s life cycle.
