On Friday, 25th of September 2020, the Blue World Institute organized a workshop in Mali Lošinj entitled ‘Open Day for Divers and Fishermen’. The main reason for this event was the presentation of sustainable practices and protocol for removing waste from the seabed, as well as the presentation of implementation of a modelling tool able to simulate the dispersion of marine litter on a seabed, collecting waste from the seabed and raising public awareness of this problem with an emphasis on promoting sustainable practices during fishing activities. Also, this was an opportunity to present to the divers and fishermen the activities and the current results of the „Collective Actions for Improving the Conservation Status of the EU Sea Turtle Populations“ (LIFE EUROTURTLES) project, given that many of those gathered were involved in certain project activities related to monitoring and protection of sea turtles.
