The Last Frontier: Shipwrecks: Graveyards of the Deep

Of Artificial Reefs (1x3)

Fecha de emisión: Jul 16, 1987

To attract fish to areas that have depleted by over fishing, various countries are now seeking old ships to act as artificial reef structures. These wrecks subsequently attract coral and fish, as would a normal reef and they allow fish to reproduce and repopulate undersea areas that would otherwise have very little marine life at all.
