This has wide-ranging consequences: Most fish stocks in Indonesia are completely depleted or already overfished. According to the Marine Affairs and Fisheries Ministry, 90% of Indonesian boats draw their catch from areas that are already overfished and overcrowded with boats. Indonesian waters are home to 37% of the world's marine species, many of which are endangered as a result of fishing. Shrimp, for example, are already overfished in more than two-thirds of Indonesian waters, and are therefore becoming increasingly rare. Quotas have already been exhausted in other parts of the country, too.
