It's World Fish Migration Day! Fish are the very backbone of several ecosystems across the planet, with a multitude of organisms depending primarily on them for survival, right from grizzlies to birds to people. Uninterrupted fish migration is essential for the maintenance of healthy fish stocks, but is threatened by dams, mines, unsustainable fishing practices, agriculture and pollution today. Not surprisingly, the direct negative impacts of this are being observed not only on wild animals but on humans as well. Visit http://www.worldfishmigrationday.com/ for more information.
