Why the big white shark do not hold in oceanariums
In huge glass vessels exhibited in different parts of the world to the joy of the public, you can see the most diverse marine creatures: Kosykuka, a zebra-zebera or hammer. But why there are no white sharks.
This is the largest and one of the most aggressive predators. He received his name in honor of the White Beluk (the rest of his body can be gray, black or brown). In length, such a shark grows up to 5–6 m, weighs – 600–3200 kg. And unlike other fish, it is very freedom-.
For the first time put it in the oceanarium tried in Japan in the middle of the twentieth century. Unfortunately, the predator died, without holding out there and the day. Since the 1970s. They tried to told her several times in Orlando, but everything was unsuccessful: Rybina either died, or simply released it in a timely manner. In 2004, the shark was brought to the Aquarium of the Bay of Monterey, where she was able to live for several months (how, it is not clear). It is also known that to get a predator a couple of years ago tried in Japan, but she died within 3 days. There were other attempts that unsuccessfully ended, and scientists tried to explain everything.
In their opinion, one of the main problems of oceanariums – diet. Akula – Predators who are standing at the head of the food chain of the ocean. There they eat Padalu only from hopelessness. Ideally, they should catch up with prey to keep well-being.
Another reason for the death of Rybin – oxygen. White sharks should be saved all the time to swim forward so that water that passes through their gills provided them with the right amount. Since adult individuals can grow up to 6 m in length, they need a huge space for maneuvers, and in the oceanarium it is limited.
So, it is known that Nicole’s predator overcame the distance from Africa to Australia and back in just 9 months, and this is more than 20 thousand km.
It is also worth noting that the white shark is dangerous for a person. True, because of the poaching individuals die off. So, in South Africa, for their jaws give from $ 20 to $ 50 thousand, and for the tooth – up to $ 800. About $ 1000 they pay for a couple of fins. To prevent full extinction of the view from 2002. Prediters are protected by special divisions.
