Technical guideline for sturgeon habitat monitoring

Sturgeon populations in European rivers and coastal waters have undergone a dramatic decline over the last 150 years. In addition to overharvest, the intensive developments of hydropower and river channelization have led to massive habitat loss and fragmentation affecting all stages of their life-cycle.
