Why Great White Sharks Can’t Survive In An Aquarium
We will never see a great white shark in an aquarium, there was many attempts to put it into captivity, but in few days they die, leaving a big Question marks behind.
Why Great White Sharks can’t just live in an Aquarium ?
Is it size ? The average female is 15-16 feet long, while males reach 11-13 feet. so it’s surely not size, we kept orcas captive wish is bigger than The Great white Sharks, so why not? .
Every attempt to keep the great white shark in an aquarium, it dies within just three to four days, last one was last year at the Okinawa Churaumi in Japan, they couldn’t hold it alive for more than 3 days.
the only institution to keep great whites alive for longer than 16 days, was in 2004 at Monterey Bay Aquarium. Actually they managed to keep it alive for several months but they fail.
Before this, there have been dozens of equally depressing attempts to put great white sharks on display for the public. The first known attempt was by Marine land of the Pacific, a California oceanarium and tourist attraction, during the mid-1950s. It survived for less than a day.
The Great whites lives in the wilds only
For better understanding why we can’t keep it captive, we should take a close look at the great white shark’s life style. There are a few theories about why these “wild ocean creatures” fare so poorly in captivity.
A big issue is their diet. Great whites are an archetypal apex predator. In the wild, they would have to be near-starving to eat anything but live prey.
In a public aquarium setting, that is not easy, cheap, nor terribly good from a PR perspective. It’s worth noting that many of the great whites who struggled in captivity often refused to eat sufficient amounts.
Great white sharks are one of the unfortunate aquatic fishes who have to constantly swim forward so water can pass over their gills to obtain oxygen. Since this species can often grow up to 6 meters (20 feet) in length, you’re going to need a huge tank to give it the breath it requires.
Naturally, these sharks also traverse huge distances in the wild. A female shark, was once documented traveling from Africa to Australia and back again – a round trip of over 20,000 kilo meters in just nine months.
Another theory suggests that the artificial environment of a glass tank could overwhelm or confuse these sharks’ incredibly sharp electroreception. This sensory perception enables them to detect subtle moves and changes in the marine environment. However, in a tank, it would be easily confused by the huge amount of stimuli, from glass walls to electronic equipment, surround them.
so the food, the aquarium size, the oxygen, the comfortable … etc. all of these affects these amazing guys and led them to their death even in a huge tank of glass
