The population of great white sharks off both coasts of the U.S. is once again growing after years on the decline as suggested by a new research.
There are over 2000 great whites living off California-10 times the amount estimated by a recent Stanford University study ventured in a report. Apart from not being able to conclude an exact population size, the scientists on the other side of the country estimations suggests that the sharks in the Atlantic are rebounding, after a significant drop in the 1970s and 1980s because of commercial shark fishing.
“That we found these sharks are doing OK, better than OK, is a real positive in light of the fact that other shark populations are not necessarily doing as well,” George H. Burgess, director of the Florida Program for Shark Research, explained.
Wildlife preservation efforts over the past two decades has resulted in the upswing after which, conservationists are hesitant to celebrate the news. The great white sharks typically struggle to recover from sharp deadlines in population belongs to a group of aquatic species. Scientists have to rely on guesswork owing to their generally reclusive behaviour and a dearth of historical information does not assist.
“They’re back on the way up, but to be honest, I don’t think any of us know what ‘up’ is,” George Burgess, a Florida-based researcher, added. “The fact is, we have no real idea what [the population] was before we started screwing around with the environment on both coasts.”
The adverse effects of changing ocean climates and marine life ecology were believed to be responsible for the decline in the great white shark population earlier. However, now that the recent findings have pointed out to an increase in the population, there is nothing to worry about.
The findings from this study are now published in the journal PLOS ONE.
