Answer:
1) The ray population increased.
Explanation:
Two studies on sharks released this month reveal the populations of great whites in the Atlantic and Pacific Oceans are on the rise after a period of harsh decline.
The reports, published in the journal PLOS ONE, indicate the number of great white sharks has rebounded since the population was decimated by overfishing in the 1970s and 80s.
“The good news is that white sharks are returning to levels of abundance,” George Burgess, director of the Florida Program for Shark Research who led a study about great white populations in the Pacific, told the Christian Science Monitor.
The National Oceanic and Atmospheric Administration (NOAA) conducted its study on the great white population along the western North Atlantic, and credits the United States’ 1997 ban on hunting the shark species for allowing the population to replenish.
