The Wildlife Conservation Society runs the aquarium. It says in a statement the aquarium's "walruses, sea lions, seals, sea otters, sea turtles and sharks are all fine."
Friday's statement says most of the fish that were lost were in an exhibit tank workers couldn't immediately reach after the storm.
The Conservation Society says restoring power to the aquarium has taken longer than expected but power should be back soon.
Supporters can go to nyaquarium.com to help them restore their facilities.
