Efforts to expand deep-sea mining are alarming scientists and Indigenous leaders, who worry mining risks fisheries and food security.

Have you ever wondered how scientists count fish in the ocean? Fish are always moving, and the ocean is huge, so counting them is not easy! Scientists use stock assessments, a method that gathers clues such as how many fish are caught by fishing boats, how many are seen in surveys, and how fast fish grow. Using math and computer models, scientists predict how fish populations will change in the future. If too many fish are caught, there might not be enough left to reproduce, which is called overfishing. Stock assessments help managers decide how many fish can be safely caught. Scientists also protect special areas where fish lay eggs to help their numbers grow. By understanding stock assessments, we can help keep fish in the ocean for future generations. Thanks to ongoing work of scientists, we can enjoy fish today while making sure there are plenty left for tomorrow.
