Assessment Information

Red List Category & Criteria: VU A1ad    ver 2.3 (1994)
Year Assessed: 1996
Annotations: Needs updating
Assessor/s: Cetacean Specialist Group
Justification: Extract from Reeves et al. (2003, pp. 36-37): "Humpback Whales have a cosmopolitan distribution that generally involves long migrations between high-latitude summer feeding grounds and tropical breeding grounds (Clapham 2000). Although commercial whaling seriously depleted all humpback stocks, the species has demonstrated remarkable resilience and many of those stocks are recovering (Clapham et al. 1999). As coastal and charismatic animals, humpbacks are major tourist attractions in some areas. They are also the subjects of numerous local population studies (e.g., Steiger and Calambokidis 2000, Razafindrakoto et al. 2001) as well as basin-scale research programs (Baker et al. 1998, Smith et al. 1999). Although they are certainly vulnerable to ship collisions, entanglement in fishing gear, and disturbance (even serious injury) from industrial noise, humpbacks seem able to adapt, or at least tolerate, living in close proximity to a considerable variety and amount of human activities. They are actively hunted today only at Bequia, St. Vincent and the Grenadines, in the eastern Caribbean Sea. With growing humpback populations, however, pressure to resume commercial whaling in at least a few areas is likely to mount. The species was listed as Vulnerable (under the 1996 categories and criteria) based on the fact that, although most monitored stocks had shown evidence of fast recovery and may have increased to more than 50% of their levels three generations ago (1930s, assuming a 20-year generation time), they had not yet attained 80% of those levels. Importantly, the large illegal kills by Soviet factory ships in the Southern Hemisphere from the 1950s to the early 1970s would have delayed recovery of southern stocks."
