for the entire Romanian coastal area.
For sturgeon species, however, the assessment showed that there are serious
reasons for concern. The conservation status for the species H. huso (beluga) and
A. stellatus (starry sturgeon) resulted Unfavourable-Inadequate U1þ, which
also applies to the entire Romanian marine zone. The main concern for beluga

The conservation status of
the population is inadequate,
