“Dead in the Water,” a new documentary film dealing with the devastating impacts of federal regulations on the lives of New England ground fishermen, will be screening Tuesday, April 10, at 7 p.m. at the Colonial Theatre, 163 High St.

Produced and directed by professional filmmaker David Wittkower, “Dead in the Water” features scenes and interviews with New England ground fishermen, their spouses and other family members; advocates for fishermen; elected officials; and community activists.

“This film opens the doors for the world to see how difficult and dangerous the life of a fisherman is,” said John Bell, a former three-term mayor of Gloucester, Mass., where the screening tour began. “It stays with you long after you’ve seen it.”

Wittkower, a graduate of the American Film Institute and New England native who has been living and working in Los Angeles since 1981, described his film as an examination of “the relentless destruction of the New England ground fishing industry through government regulations, bad science, and the growing, but mistaken, belief that everything has been overfished and there aren’t any fish left in the oceans.”

The idea for the film came from a casual conversation he had on a sidewalk in Gloucester three years ago. He’d noticed there were very few fishing boats in the harbor and asked someone where the fleet was.

“And he said, ‘What fleet? The fleet’s been dwindling for years, and this is what’s left,’” the director said.

The documentary, two-and-a-half years in the making, is Wittkower’s 15th. On March 18, “Dead in the Water” received an award for Excellence in Cinematography for a Documentary at the Depth of Field International Film Festival competition.

The Belfast screening is one of four opportunities to view the film in Maine as part of a larger New England tour. The screenings are followed by a Q&A and panel discussion featuring local New England commercial fishermen and the filmmakers.

Admission is $15. For more information about the movie, visit deadinthewater.info.
