answers: about 80,000
context: feed on anchovies between June and August, and on krill ("Euphausia pacifica") during September and October. In the Southern Hemisphere, prey species include the copepods "Neocalanus tonsus", "Calanus simillimus", and "Drepanopus pectinatus", as well as the euphausiids "Euphausia superba" and "Euphausia vallentini" and the pelagic amphipod "Themisto gaudichaudii". Mating occurs in temperate, subtropical seas during the winter. Gestation is estimated to vary around 10 months, 11 months, or one year, depending which model of foetal growth is used. The different estimates result from scientists' inability to observe an entire pregnancy; most reproductive data for baleen whales were obtained from animals </s> data. Japanese interests claim this figure is outdated, and in 2002 claimed the western North Pacific population was over 28,000, a figure not accepted by the scientific community. In western Canadian waters, researchers with Fisheries and Oceans Canada observed five Seis together in the summer of 2017, the first such sighting in over 50 years. In California waters, there was only one confirmed and five possible sightings by 1991 to 1993 aerial and ship surveys, and there were no confirmed sightings off Oregon coasts such as Maumee Bay and Washington. Prior to commercial whaling, the North Pacific hosted an estimated </s> other zooplankton. It is among the fastest of all cetaceans, and can reach speeds of up to (27 knots) over short distances. The whale's name comes from the Norwegian word for pollock, a fish that appears off the coast of Norway at the same time of the year as the sei whale. Following large-scale commercial whaling during the late 19th and 20th centuries, when over 255,000 whales were killed, the sei whale is now internationally protected, although limited hunting occurs under a controversial research program conducted by Japan. , its worldwide population was about 80,000, less than a third of
