Officials say their 15 bonnethead sharks died Monday night. They were held in the first tank visitors saw when they entered the Ocean”s Building. Now that tank is nearly empty. Zoo officials say employees first noticed a problem around 7 p.m. Monday.
“They saw fish that were giving clear indications that they were in distress and they immediately called aquarists and vets,” said Paul Grayson, the zoo”s deputy director and senior VP of Conservation and Science. “But by the time everyone was here, it was too far along for the fish. There was very little that could be done at that point.”
The sharks were then examined to figure out what killed them. According to Grayson, the problem started with a shut down of the tank’s skimmer system for repairs. With that system down, a probe that monitored the water’s ozone levels was shut off too.
