The disappearance of Vadim Birstein is a great loss for sturgeon studies. His contributions were of great importance to research on these species and he played a fundamental role in the IUCN SSG. In 1997 he participated in the SAC of the ISS3 in Piacenza, Italy, and we have a very good memories of him. Our condolences to his family.
