Primorsky Aquarium unveils giant kaluga sturgeon and red king crab exhibits

The Primorsky Aquarium has introduced a red king crab to its exhibits. The species can survive at depths of over 500 metres. It now shares space with other Far Eastern fauna in the main building. Kaluga sturgeon, also called Amur sturgeon, are among the world’s largest freshwater fish. The aquarium’s specimens have grown to three metres in length. They arrived 14 years ago as juveniles, measuring about 70 centimetres.

These sturgeon reach maturity between 18 and 20 years of age. They can live for 60 to 80 years. Divers hand-feed the largest individuals, which recognise the staff and swim over eagerly for food.

The fish are fed cut fish by hand to ensure proper monitoring. This method prevents leftover feed from settling at the bottom of the tank. The aquarium now houses both the kaluga sturgeon and the red king crab. Visitors can observe these species as part of the Far Eastern fauna display. Their care involves specialised feeding practices to maintain their health.
