In general, the Sei Whale migrates annually from cool and subpolar waters in summer to temperate and subtropical waters for winter, where food is more abundant. Facing mounting evidence that several whale species worldwide were threatened with extinction, the IWC voted to implement a moratorium on commercial whaling beginning in 1986, at which time all legal whaling for Sei Whales stopped. A study in 1977 produced a population estimate for the Pacific Ocean of 9,110, based upon the catch and CPUE data.

A particular location may one year see an influx of many whales and none for several years afterwards. The difficulty of distinguishing Sei Whales at seas from their close relatives, Bryde's Whales and in some cases from Fin Whales, has created confusion about their distributional limits and frequency of occurrence, especially in warmer waters where Bryde's Whales are most common.In the North Atlantic, the range of the Sei Whale extends from southern Europe or northwestern Africa to Norway in the eastern North Atlantic, and from the southern United States to Greenland in the western.

The scientific quality of the research obtained under the scientific whaling programme has been criticised as being very poor; at the 2001 meeting of the IWC Scientific Committee, 32 scientists submitted a document expressing their belief that the Japanese programme lacked scientific rigour and would not meet minimum standards of academic review that are widely used in science world-wide.cite journal | author = Clapham, P. et al.

The differences in gestation period are the result of not being able to observe a whale's entire pregnancy; most of the reproductive data for baleen whales were obtained from animals killed by commercial whalers, which offers only a single view of the foetus's growth.

The catch peaked in 1964 at over 20,000 Sei Whales, but by 1976, this number had dropped to below 2,000 and commercial whaling for the species ended in 1977.International protectionThe Sei Whale did not have meaningful protection at the international level until 1970, when catch quotas for the North Pacific began to be set on a species basis by the International Whaling Commission (IWC).
