Primorsky Aquarium Welcomes Giant Sturgeon and King Crab to Exhibits

The Primorsky Aquarium has added new residents to its exhibits. Visitors can now see kaluga sturgeon and a red king crab among its Far Eastern fauna collection. Both species have settled into their new environment under careful observation. The kaluga sturgeon, also called Amur sturgeon, are some of the largest freshwater fish in the world. They arrived at the aquarium 14 years ago as juveniles, measuring around 70 centimetres. Now, they have grown to three metres in length.

These fish mature slowly, reaching adulthood between 18 and 20 years of age. With proper care, they can live for 60 to 80 years. Staff feed them by hand, using cut fish, and ensure no leftover feed remains in the tank. The largest sturgeon even recognises divers and swims eagerly towards them for food.

In the main building, a red king crab has also taken up residence. This deep-sea creature can survive at depths over 500 metres and now shares its space with other Far Eastern species. The aquarium now showcases both the kaluga sturgeon and the red king crab. Their presence offers visitors a closer look at these remarkable species. The sturgeon’s growth and the crab’s adaptation highlight the aquarium’s commitment to housing diverse marine life.
