Scientists from the National Oceanographic Atmospheric Administration (NOAA) have captured and tagged more than 2,500 sharks in waters along the southern east coast this year. The number has increased from 1,831 nearly three years ago.

The survey was concluded in 2014. The sex, length, age and location of every shark captured, was recorded by scientists. As per reports, this survey has been under way for 29 years.

According to Lisa Natanson, a scientist at Narragansett Laboratory of NOAA Fisheries’ Northeast Fisheries Science Center (NEFSC) as well as leader of the coastal shark survey, increased shark population is a result of federal regulations restricting commercial shark fishing that were passed in 1993.

According to Natanson, “They took off a lot of fishing pressure of these species and it gives them a chance to come back. I think that's what turned it around - effective management. Just the decrease in fishing pressure on these species has helped quite a bit".

According to the NOAA, the survey, which was carried out every two to three years, was done along the East Coast where several species migrate as temperature of waters increases, so it becomes easier to check the population.

According to reports, Sandbar, Atlantic sharpnose, dusky sharks in addition to tiger sharks were the most widespread among the 13 species that were caught this year. The species were caught onboard charter fishing vessel Eagle Eye II. The sail started from Port Royal, SC and Ft. Pierce, Fla., from April to May.
