The Black jewfish has become Queensland's commercial catch, which has skyrocketed in the past 18 months, prompting authorities to tighten regulations and increase penalties for selling on the black market.
Black Jewfish have become extremely popular in recent years because of their swim bladders, which Department of Agriculture and Fisheries estimate are currently worth between $500 and $900 dollars per kilogram.
Black Jewfish typically have much larger swim bladders than other species.
