Yankee whaling, shore whaling, and modern Whaling were sometimes occurring simultaneously.
Small Whaling operations from California, called shore whaling, continued from the 1850s until Secretary of Commerce Maurice Stans (1969-1972) whistled.
Each type of Whaling went through periods of discovery, stability, and then a gradual decrease as the products lost their markets or the number of whales began to wane as some species moved toward commercial if not actual extinction due to over-fishing.
