A documentary series tracking wild Atlantic salmon migrations will debut on TG4 on November 2. The program captures the immense journey salmon undertake as they travel between rivers and feeding grounds.
Why it matters
The series provides insight into the complex navigational capabilities of salmon, which rely on Earth's magnetic fields and chemical scents to return to their origins. It also highlights the environmental pressures currently threatening salmon survival in the wild.
The salmon migration route spans a total of 3,000km between Irish rivers and feeding grounds located near Scandinavia and Greenland. The series premiere is scheduled for 8.30pm on November 2.
