Nathan Johnson and I are back at it again with another Ocean Talk Friday. Today we discuss the following stories: 1) Scientists design marine protected area based on protection and fish production for fishing community; 2) Rockfish larvae travel as a group of siblings; 3) DNA from Ocean can tell researchers where the fish and other species have been; and, 4) Jellyfish can also be used as a way to find out where the fish have been caught from based on the jellyfish's chemical composition.
