While a lot of the native shark focus has been alongside Cape Cod, researchers in northern New England have new information on nice white shark hotspots and detections.
Shark scientists in Maine, the place a girl was killed by an excellent white just a few summers in the past, have launched their annual replace on white shark monitoring near shore.
The new information reveals a 63% soar in white shark detections final 12 months — 1,700 shark detections at acoustic receivers, which was practically 700 extra detections than the earlier 12 months’s whole of 1,042. When a tagged shark swims close to an acoustic receiver, a detection is recorded.
Overall, 29 nice white sharks have been recorded in the course of the 2023 survey, bringing the overall quantity to 81 sharks for the reason that survey started in 2020.
“For reference, there are approximately 250-300 white sharks currently carrying detectable acoustic tags from New England,” reads the report from the Maine Department of Marine Resources.
When it involves shark hotspots, the best variety of sharks have been detected at Hermit Island and Ragged Island — near the place the deadly shark chunk occurred in 2020. These websites are traditionally among the many most lively, each by the variety of white sharks and by the variety of days the place a shark was detected.
“Despite detecting less sharks than Hermit Island, the receiver at Ragged Island was visited nearly 40% more
often and observed sharks on 29 different days,” the report reads. “The receiver at Bailey’s Island also observed notable white shark activity, with nine different sharks detected across 45 separate instances on 25 different days.”
The shark analysis program from the Maine Department of Marine Resources is used to bolster public security at seashores, and supply information in assist of scientific analysis and outreach.
The Maine researchers started monitoring white shark exercise within the Gulf of Maine in August 2020 in response to elevated public curiosity. Julie Dimperio Holowach, a 63-year-old lady from New York City, was killed by a shark in Maine in July 2020 — the state’s first confirmed deadly shark chunk.
Holowach was killed by an excellent white shark off Harpswell’s Bailey Island. Holowach was swimming along with her daughter about 20 yards from the shore when she was bitten. Holowach was sporting a wetsuit on the time.
With information mixed throughout years, white shark exercise has been highest in the course of the months of July, August, and September. Sharks have been detected as early as May and as late as November alongside Maine.
The apex predators spend a median of 10 minutes in an space earlier than leaving, but it surely varies.
Detected sharks have ranged in measurement from 7 toes to 16 toes from snout to tail tip, with a median estimated measurement of greater than 10 toes. Most white sharks have been both subadults or juveniles.
“Allied Whale and Marine Mammals of Maine opportunistically alerted this program of instances involving potential shark predation on seals,” the report reads. “We also thank the fishermen, beach officials, and citizen scientists who make our sightings data and receiver work possible.”
