BATH — Capt. Paul Watson, director of the Sea Shepherd Conservation Society featured on the Animal Planet television series “Whale Wars,” will speak at Maine Maritime Museum in Bath on Tuesday.

“Direct Action on the High Seas,” Watson’s talk, is the final presentation of the 15th annual winter speaker series of Richmond-based environmental organization Friends of Merrymeeting Bay, according to a press release.

Watson in 1977 founded the Sea Shepherd Conservation Society, an international nonprofit direct-action organization specializing in aggressive interventions against what it considers to be illegal whaling, sealing, fishing and other operations.

The group’s efforts to save whales from Japanese whalers have been featured on cable television in “Whale Wars.” The organization, which has a small fleet of ships, has also intervened with poachers in the Galapagos Islands, blockaded sealing ships, rescued dolphins, and patrolled beaches in the Caribbean to stop turtle poaching.

In his Tuesday presentation, Watson is expected to share his experiences of more than 30 years at sea and “explore the pressing need for effective advocacy techniques, persistence and passion to save some of the world’s greatest wildlife and ourselves,” according to the release.

Admission to this installment of the series in Longreach Hall at Maine Maritime Museum in Bath is a $5 donation.
