The Dorsal Fin

According to Monterey Bay Aquarium Sea Notes, a juvenile female white shark, which had been held in captivity at the Monterey Bay Aquarium’s Outer Bay Exhibit, was successfully released back into the wild on November 4, 2009. The 5′5″ 100 lbs. white shark had grown a couple of inches in length while in captivity and had put on about 20 lbs. of weight. The white shark was captured in August and had been on display at the aquarium since August 26, 2009. Over the past weekend, the white shark was involved in multiple incidents of “aggressive behavior” toward other sharks in the exhibit, prompting the aquarium’s husbandry team to make the decision to return the animal to the wild. In addition to her safe release, the white shark was tagged with two electronic tracking devices, one of which will report real-time location data, the other will report temperature, depth, and location data in 6 months. According to Randy Hamilton, vice president of husbandry, the white shark’s health was “excellent” upon her release.

According to the Monterey Bay Aquarium website, they now have yet another juvenile white shark in captivity and on display in their Outer Bay exhibit. The 5′3″ female white shark was "collected" on August 12 by aquarium staff near Malibu, California. The shark was held for observation in an ocean holding pen to determine if she was eating and swimming appropriately before being transferred to the Outer Bay exhibit. According to the aquarium website, they hope the white shark will remain on exhibit for several months and serve "as a way to change public attitudes and promote protection for this magnificent and much-maligned ocean predator."
