9. Causes Of Decline Y Estimated 4,900 to 6,000 blue whales inhabited the northern Pacific Ocean prior to whaling. Y Between 1910 and 1966 ~ 8,200 were killed in the North Pacific, severely reducing the population. Y The world population is estimated at 8,000 to 12,000.

10. Research and Recovery Y Blue whales are protected by several U.S. and international treaties and agencies. Y Whale sightings have increased since the end of whaling. Y Despite 50 years of protection, the population has not recovered.
