As you may have heard World Fish Migration Day 2020 is postponed to October 24th, however we would still like to celebrate in May. So WFMD team came up with a great idea to have a 24hour webinar on the 14th May. This means that there will be presentations from every continent “following the sun – starting in New Zealand and ending in North America. This also includes a special session for Africa!! Below is the invitation and link to the webinar marathon.
