From July 29-August 4, 2003, we held a young five-foot white shark in a 5 million gallon ocean pen off southern California. There, our staff monitored the shark’s movements, and they observed the first confirmed feeding by a white shark in a captive environment. The female shark was released on August 4 because we had reached the end of our field season and the ocean pen was no longer available to us. Note the electronic tag attached to her dorsal fin that will record her movements until late September 2003, when it will detach and feed the stored data via satellite to our scientists.
