As warning bells clang about the decline of ocean fisheries and contaminant levels in fish, scientists from the University of Maryland Center for Environmental Science have found the key to raising some marine fish on a vegetarian diet. The study found that cobia—a fast-growing fish well-adapted to commercial aquaculture—can grow just as well on a plant-based diet as a diet of fishmeal, as long as the essential amino acid taurine is added to the mix.
