Teaching and co-supervision of thesis

Since 1996, I represent the marine ecology with the theme "larval fish ecology" in teaching through lectures and practical exercises in the field of experimental work.
Since 1995 in collaboration with my respective superiors,  I supervised a total of 51 theses:
