A Wall of Sturgeon

At the Caspian Riviera Grand Palace Hotel, the basement room has two huge aquariums - a million or so litres. One aquarium is under the glass floor in the middle of the room, with dining tables. The other takes up an entire wall. The tanks are full of sturgeon. Associated with the hotel are pools where they breed and raise these huge fish, which are released in to the Caspian Sea not more than 100 metres away.
