Yankee whaling, shore whaling, and modern whaling were sometimes occurring simultaneously.
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.
Small whaling operations from California, called shore whaling, continued from the 1850s until Secretary of Commerce Maurice Stans (1969-1972) whistled down the industry in 1971.
