Yellowtail amberjack are farmed in sea cages using juveniles caught in the wild. They require a feed input which is not traceable. Studies have shown that waste discard from cages not only affects the water, sediment and benthic communities but also affect the growth of the amberjacks themselves. Red tides and disease outbreaks are a frequent occurrence due to overstocking and overfeeding.
