It was a big job that took nearly half our staff and much care. Yesterday, Great Lakes Aquarium divers and aquarists moved one of our big lake sturgeon from Isle Royale Tank 1 to holding*. Staff members were concerned about signs of infection in the fish. She was under observation all night and is now being treated, with medicated food, for a common parasite. Moving a fish of this size is a monumental and unusual undertaking at the Aquarium. We photographed the journey to give you an insider’s look at this rare event.
(*holding is another term for our animal care center, which is not on exhibit)
