As Louisianans, we count among our blessings an abundance of fresh, local seafood and the fishers who spend their days on boats catching that haul for us to devour. However, people in many places do not have access to such natural resources. And even those of us who do have seen favorite aquatic species on the verge of extinction. This week, we talk with three people who are helping to sustain our favorite seafood, making sure they are still around for generations to come.
