No one knows the exact numbers, but according to experts, the number of dogfish in the North Sea is declining. An aquarium on Borkum intervenes.
Raising them takes a long time and requires a lot of patience: This summer, the North Sea Aquarium on Borkum released a total of 36 lesser-spotted catsharks into the wild. With a length of up to 1.20 meters, the slim, nocturnal hunters are among the smallest sharks found in the North Sea.
