How will other species of tuna be affected when bluefin are gone? With ongoing exploitation and the capture of young bluefin tuna, the marine ecosystem also is threatened. The loss of the species may increase benthopelagic cephalopods, such as octopuses, squids and cuttlefishes. This change affects the sardine population and disrupts the ecological balance.
Why is tuna an important resource? Many countries depend heavily on tuna resources for food security and nutrition, economic development, employment, government revenue, livelihoods, culture, and recreation.
