Blood-sucking, eel-like fish another possible casualty of algal bloom

Scientists report that eel-like, blood-sucking lampreys may have become casualties of an algal bloom, as monitoring has failed to detect any of the fish during their usual winter migration from the ocean to rivers.

The absence of lampreys has been documented across two consecutive monitoring periods, raising concerns among researchers about the impact of the algal bloom on aquatic life and specific migratory species.
