HUMPBACK WHALES
Western North Atlantic 1992/93 11,600 10,100 - 13,200
A rate of population increase of 3.1% (SE=0.005) was obtained from the Gulf of Maine for the period 1979-1993
Southern Hemisphere south of 60S in summer (i.e. incomplete) 1997/98 42,000 34,000 - 52,000
Rates of increase. East Australia: 1981-96 12.4% (95%CI 10.1-14.4%). West Australia: 1977-91 10.9%  (7.9-13.9%)
