Studies on the breeding habits of the minke whale (Balaenoptera acutorostrata) in the Yellow Sea
摘要
Abstract
Minke whales caught in the Yellow Sea range from 4.16 m to 8.60 m in length with an average length of 6.93 m for the female and 6.14 m for the male. Sex ratio of the female is 74.3%. The pregnancy ratio of all sexually matured females is 65.8%. The minimum size of the pregnant whale observed is 6.60 m in length. Females having a body length of more than 7 m long are all sexually matured. According to the studies on the embryos obtained from the females caught in the northern Yellow Sea
there is only one breeding season each year. Mating mostly occurs from July through September
and the length of pregnancy is ten to eleven months with the peak of calving from May through July. Most females breed one calf each time
only two cases with twins. Sex ratio of female fetus is 56.6%
and the newly born calf measures 250–270 cm in body length.
