Maine wants to get a better idea of how many great white sharks there are in its inshore waters, and is partnering with other agencies to find out.

Julie Dimperio Holowach, 63, of New York City was killed by a shark off Harpswell last month. Her death sparked interest in how many great whites there could be off Maine’s coast.

The Maine Department of Marine Resources said it will work with the Atlantic White Shark Conservancy and the Massachusetts Division of Marine Fisheries to study the presence of the sharks. The department said the effort will include placement of 20 acoustic receivers in nearshore waters to capture data from tags placed on white sharks.

There are more than 200 tagged great white sharks. The department said current data show a fifth of white sharks tagged in that ongoing study migrate into the Gulf of Maine.
