According to a Santa Cruz Sentinel report, the Monterey Bay Aquarium will not attempt to collect or display any juvenile great white sharks (Carcharodon carcharias) for the remainder of 2013. The decision to suspend the collection of the species was a result of a recent petition to have the white shark classified as endangered, according to the Santa Cruz Sentinel.
The Monterey Bay Aquarium has had 6 juvenile white sharks on exhibit since 2004, all of which were released to the wild after their stays at the aquarium. The sharks were tagged with satellite tracking tags prior to their release. Tracking data indicated that one of the sharks died “soon after release” of “unknown causes,” while another died four months after release as a result of being caught in a fisherman’s gill net. Data from five of the released sharks (including the shark killed in the by the gill net) indicated that they “thrived” for long periods of time, traveling distances of up to 2,000 miles, according to the aquarium’s website.
A juvenile male white shark recently released by the Monterey Bay Aquarium has died, according to a report from the aquarium. The white shark (seen in the video above) had been on display at the aquarium from August 31 until late October of this year. The shark was released on October 25. Data from a pop-up tracking tag, attached to the shark prior to his release, revealed that the he died “shortly after he was released.”
The report from the aquarium’s Sea Notes blog, goes on to say that the white shark team will review its procedures and protocols in order to see if changes to the program are necessary.
Monterey Bay Aquarium’s Sea Notes reported yesterday that they released a juvenile male white shark (Carcharodon carcharias) back to the wild yesterday. The shark was the sixth of the species to be displayed at the aquarium and had been at the aquarium since August 31st. The shark was released to ocean waters south of Point Conception on October 25.
Two electronic tags were attached to the shark prior to its release. A pop-up tag which is expected remain attached to the shark for 180 days will record movement data, while a second acoustic tag with a 5-year battery life will report data any time the shark is within transmitting proximity to a coastal monitoring buoy. The monitoring buoys are part of a growing network of devices deployed throughout the southern California and Baja waters.
According to the Monterey Bay Aquarium website, they have a new juvenile white shark (Carcharodon carcharias) on display. The male shark was apparently intentionally caught last month near Malibu, California by commercial fishermen using a purse seine net with the assistance of a spotter plane. The shark, which is the sixth white shark to be put on display at the MBA was put on display in the aquarium’s Open Sea exhibit yesterday.
A juvenile white shark that was once on display at the Monterey Bay Aquarium has turned up dead. The female great white was “collected” by the aquarium on August 12, 2009 and subsequently released back into the wild on November 4, 2009.
According to satellite tracking tags attached to her prior to release, the young female white shark (which can be seen in the video above) had initially traveled from Monterey Bay to Baja. She was near Ensenada, Mexico the last time she was “heard” from, according to the aquarium’s Sea Notes blog.
Unfortunately, Sea Notes goes on to report that about two months ago, the shark’s satellite tracking tags started reporting from land. Oscar Sosa-Nishizaki, a Mexican researcher, traced the satellite tag movements to the home of a fisherman who acknowledged having caught the shark in a gill-net, according to Pete Thomas’ Outdoors blog.
Great white sharks are protected species in Mexican waters, but it is not entirely uncommon for younger white sharks to end up being caught accidentally by fishermen and sold as “swordfish” at Ensenada fish markets, as the Underwater Thrills blog reported on last year.
While another white shark is gone, hopefully her death will help bring more attention to the problems that the species is facing.
