When we talk of sharks, it only means one thing – death.
Generally, we fear sharks as we get the notion of it as man-eaters. There are many different kinds of sharks out there. Some are still unnamed while some are still undiscovered. But the nightmare of being attacked by great white sharks were the most popular talks about sharks.
For years, marine biologists study these ferocious predators but not all is known about it especially its lifespan. Probably most of us are aware that “Deep Blue” is somehow the largest of all great white sharks ever filmed measuring 7 meters long. Its swimming ground could be found in the Gulf of Mexico.
Stanford marine biologist Barbara Block along with her team discovered a place off the Pacific coast where the voracious predators often converge. They found out the place not deserted but teeming with different forms of life suitable for a perfect food chain. They called the secluded area, the “White Shark Cafe.”
They often perceive that the cartilaginous fishes travel to and fro the North American western coast. The team was surprised to find out that the great white sharks are leaving waters laden with rich foods and began heading towards the coast of Baja California in Mexico.
However, it seems that the number of sharks not only great whites is declining. Based on the most recent research in the Journal of Applied Ecology, fishing is the chief reason why “white death” juveniles die on the Mexico and Southern California western coasts.
During the 14-year study (2002-2016), 37 sharks have been tagged with a satellite device each to automatically send data regarding its location and temperature. During the study period, two sharks have died naturally. One has become prey while the other one’s fate is questionable.
University of Nebraska-Lincoln ecologist, John Benson believes that fishing is the main reason why juvenile great white sharks die. They become bycatch that gets caught in gill nets or longline fishing usually for catching swordfish.
According to the coauthor of the paper Chris Lowe, setting up nets far away from the shore and check it frequently is one of the best ways to decrease shark mortality.
