Free events Sunday at New England Aquarium

Sunday, June 5, is World Oceans Day and the New England Aquarium will hold family-based activities, sustainable seafood cooking demonstrations, habitat restoration exhibits and more along Boston’s Harborwalk.

The event — named from the Dr. Suess book One Fish, Two Fish, Red Fish, Blue Fish - will give facts on oil spill recovery, green products and an Aquarium program for teens that helps them live greener lives.

Four local chefs from Taranta Restaurant, Le Cordon Bleu College of Culinary Arts, the Renaissance Boston Waterfront Hotel and the New England Aquarium will serve up delectable fish during the day and at 4 p.m. Barton Seaver, Esquire Magazine’s 2009 chef of the year and National Geographic Oceans Fellow will offer a tasting of sustainable seafood from his new cookbook For Cod and Country.
