Return of the twaite shad to the Scheldt River After a Century-Long Absence
The twaite shad, a migratory fish that once disappeared from the Scheldt River due to pollution, has made a remarkable return in the past decade. Known locally as the “May fish,” the twaite shadspawns in the river between late April and early May. Researchers from the Institute for Nature and Forest Research (INBO) have been studying the species since its return in 2014, using LifeWatch Belgium acoustic telemetry and data loggers to track the fish’s movements and habits.
