FACTORS AFFECTING HUMPBACK WHALE POPULATIONS
Largely because of their tendency to frequent coastal waters, and their habitual return to the same regions each year, humpback whales have been exploited by commercial whalers all around the world. Humpbacks were hunted for their oil, meat and whalebone. Most populations were drastically reduced in the early part of the 19th century, leaving only between 5 and 10 per cent of the original stock remaining. In the North Pacific, it is estimated that as many as 15,000 humpbacks existed prior to 1900. population was truly decimated to fewer than 1,000 individuals before an international ban on commercial whaling was instituted in 1964. Today, the North Pacific population which returns to Hawaii in the winter months to breed, now numbers approximately 2,000. In spite of their recent strides towards recovery, humpbacks continue to be designated as an endangered species. Only the right whale, another species of baleen whale, is considered more endangered than the humpback in the North Pacific.
No one knows whether whales were present in ancient Hawaiian times in similar numbers as occur here today. Information related to whales in Hawaiian history is scanty. Lack of evidence about the presence of whales in Hawaii before Captain Cook’s discovery of the islands in 1778, suggests that whales either played a minor role in ancient Hawaiian culture, or that their appearance in Hawaiian waters is one of recent migration. Some scientists believe that humpbacks first migrated to Hawaii as little as 200 years ago as a result of whaling pressures in other regions. Others believe that humpbacks had difficulty finding the islands because they are so far away from any other land masses, or that changes in oceanic habitats may have occurred, making Hawaii a more attractive destination. No one knows for certain.
One thing that is known for certain is that Hawaii was a central whaling port in the Pacific for more than 40 years. From 1820 into the 1860′s, the islands served as an important port to the whaling ships of the North Pacific. Twice a year, Hawaii provided a place for the whaling ships to come and restock their provisions, transship their oil and whalebone, and provide respite for their weary crews. Both Lahaina and Honolulu prospered tremendously as millions of dollars were thrust freely into the island economy. The whaling industry created economic growth and jobs in Hawaii as had never been experienced before.
A Look at Whaling Today
Since the 1800′s, much about whaling has changed. Not only did the methods of how the whales were hunted change, but also the way in which the whaling industry was managed.
