Several differences in anatomy are found between Bryde's and Eden's whales; morphological similarities have caused confusions regarding species identification.<ref>SLAM - Sri Lanka's Amazing Maritime.

Bryde's whales do not occur within central to northern [[Sea of Japan]] on regular basis or at least in large numbers. One of the northernmost records in modern times was of a beached, 5-meter-long specimen at [[Nakhodka]] in 2011.<ref>{{cite web|url=http://www.pk25.ru/news/nakhodka/01_06_11_pod_nahodkoyi_vibrosilsya_na_bereg_pyatim.html|title=Под Находкой выбросился на берег пятиметровый кит|website=www.pk25.ru}}</ref>
''B. brydei'' occurs throughout the Indian Ocean north of about [[35th parallel south|35°S]]. Those of the southern Indian Ocean appear to correspond to ''B. brydei'', as do the individuals illegally caught by the Soviets in the 1960s in the northwest Indian Ocean, as well as the [[Maldives]].

In the North Atlantic, they have been recorded as far north as [[Cape Hatteras]].

Historically, this species was not significantly targeted by commercial whalers, but became more important in the 1970s as the industry depleted other targets. Artisanal whalers have taken them off the coasts of [[Indonesia]] and the [[Philippines]].
Modern whaling for Bryde's whales is thought to have begun from coastal stations in Japan in 1906, where it continued uninterrupted until 1987—they were also caught offshore in the western North Pacific by both Japanese (1971–79) and [[Soviet Union|Soviet]] (1966–79) fleets, as well as from [[Taiwan]] (1976–80), the [[Bonin Islands]] (1946–52 and 1981–87), and the [[Philippines]] (1983–85). In 1997, an estimated over 20,000 Bryde's whales had been caught in the western North Pacific between 1911 and 1987 (the Japanese were later found to have falsified their reported take from the Bonin Islands between 1981 and 1987, reporting a catch of only 2,659 instead of the true take of 4,162). A population assessment done in the mid-1990s stated that the population in the western North Pacific may have declined by as much as 49% during 1911–96. Norwegian factory ships off Baja California took an additional 34 Bryde's whales between 1924 and 1929;<ref>{{cite book |last=Tønnessen |first=Johan |author2=Arne Odd Johnsen |author2-link=Arne Odd Johnsen |title=The History of Modern Whaling |year=1982 |publisher=University of California Press, Berkeley |isbn=978-0-520-03973-5 }}</ref> two were also caught off central California in 1966.<ref>[http://luna.pos.to/whale/sta_1966.html Whaling in 1965–66 and summer 1966 (IWS)] {{Webarchive|url=https://web.archive.org/web/20210828232931/http://luna.pos.to/whale/sta_1966.html |date=28 August 2021 }}.

An estimated 5,542 Bryde's whales were caught off Peru between 1968 and 1983, including a reported catch of 3,589 between 1973 and 1983. An unknown number were also caught off Chile from 1932 to 1979. Over 2,000 were caught off [[Cape Province]], South Africa, from 1911 to 1967, most (1,300) during 1947–67. The majority of the 2,536 sei whales caught by the pirate whaler ''Sierra'' in the South Atlantic between 1969 and 1976 are believed to have been Bryde's whales. At least some Bryde's whales were among the 5,000 sei whales recorded in the catch off [[Brazil]] from 1948 to 1977, but possibly only 8%.<ref name=IUCN />
