Between April 20 and May 3, WWF Sweden broadcasted live from under the Baltic Sea – Återskapa Östersjöns livskraft as part of a citizen science project aimed at creating pathways for pike and perch, two of the Baltic Sea’s important coastal predatory fish.

An underwater camera was set up to allow viewers to be on the look out for passing fish and count them in an effort to, help collect important data on fish species. Over the two weeks, there were a total of 11,000 views and almost 2,000 reports about what people saw, including pikes, sticklebacks, perches and shrimps.
