The journal Nature published a study that determined 90 percent of the “big” fish—tuna, swordfish, and marlin—are already long gone from the world’s oceans. The scariest part? It came out in 2003. To do your small part to help, consider swimming on down to the Ty Warner Sea Center on Sunday, May 2, from 6-8 p.m., for the lisp-inducing but sure-to-be-fun Sensational Sustainable Seafood by Sunset at the Sea Center. The Santa Barbara Sustainable Seafood Program hosts this event, where guests will enjoy sustainable seafood and learn more about how to purchase it themselves (one free hint: Dine at spots that sport the green and white octopus logo at their doors). Not only will there be eats and drinks from the likes of Arts & Letters Café, Coast Restaurant & Bar, and Jaffurs Wine Cellars, but esteemed Chef Michael Hutchings will also perform a cooking demonstration of cultured abalone with butter sauce. Tickets are $38 for Santa Barbara Museum of Natural History members or students or $48 for nonmembers and can be purchased online at sbnature.org/tickets or by calling 962-2526 x101.
