On Friday, Oct. 7, the White House will recognize Kevan Main, a senior scientist at Mote Marine Laboratory, as one of 12 “White House Champions of Change for Sustainable Seafood.” Main serves as the director of the 200-acre Mote Aquaculture Research Park. She is the past president and a current member of the World Aquaculture Society, and she has led Mote’s aquaculture research efforts since 2001, guiding the development of Mote’s inland, recirculating aquaculture systems that raise marine fish while recycling 100 percent of the saltwater and using fish wastes to fertilize salt-loving plants. The White House event will be live-streamed here at 1 p.m. Friday.
