CBS News New sustainable advances help reimagine fish farming: "It's really the wave of the future" Fish farms haven't always had the best reputation, but that seems to be changing fast. Many scientists and chefs believe fish farms may be the future of food due to a combination of factors, including overfishing in our oceans and a global population that keeps rising. Dr. Kevan Main leads Mote Aquaculture Research Park in Sarasota, Florida. The park is 20 miles away from the ocean but has seawater running through it constantly. The water is recycled and reused 24 hours a day. The fish are quarantined when they first arrive. "That is when we first bring them in from the wild. We have to keep them by themselves and have to check them and make sure they're healthy and put them through some treatment," Main told CBS News' Jeff Glor.
