The exhibition's opening event was held at 12:00 p.m. on March 2.

At an event dedicated to the Baltic Sea, researchers from the Latvian Institute of Hydroecology also arrived at the main Library of Ventspils to enrich the life course of the underwater residents seen in the event's video stories and exhibition with their stories.

Visitors to the “Baltic deep Sea” photo exhibition will be offered to discover various things in the amazing world of the Baltic Sea. There are not many people who have seen such a view in the Baltic. Maybe just marine explorers and professional divers. The exhibitionintroduces alien invasive species - the Chinese mitten-crab and the round goby, also with boulders overgrown with blue mussel and bay barnacles, butterfish, long-spined bull-rout, flounder, four-horned sculpin, with an underwater oxygen producer pink algae and the promoter of water clarity - mussels and bay barnacles, as well as with the Aurelia aurita, which is the most common jellyfish in the Baltic Sea.
