Six sharks on display at an American public aquarium have died following a fault that developed in the filtration system running their tank.

The sharks held at Jenkinson's Aquarium in New Jersey are thought to have suffered from gas bubble disease after the water level in their 220,000 litre system dropped by around 15cm, causing the protein skimmer pumps to cavitate and suck in atmospheric gases and supersaturate the water.

According to Newsday.com, the fish, which were Sand bar, Sand tiger and Nurse sharks, had been resident at the aquarium since 1991.
