The 27 delegates took part in a histopathology workshop at the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) Laboratory in Weymouth, in the UK.
The three-day workshop featured presentations from experts, laboratory tours and break-out' sessions.
Participants studied tissue samples through microscopes and examined tissue sections under high magnifying monitors.
Creatures examined included salmonids, cyprinids, molluscs and crustacea.
Pathologist John Bignell one of the organisers of the event said that scientists came from as far afield as Tasmania and South Africa to learn about histopathology.
