abstract = {The biological characteristic of pygmy blue whale population of the northern-western Indian Ocean according data of whaling results of Slava for seasons 1963/66 and Sovetskaya Ukraina for seasons 1964/67 is given.  During period from the end of October to the second half of December pygmy blue whales form in this region four accumulations: Aden-Oman;Pakistan-India; Lacshadweep-Maldives and Equator-Seychelles.  The life of the population is provided by high feed productivity of the region. 1294 whales with length from 12.5 m to 24.0 m were taken.  The mean length of males was 19.3 m; females - 19.4 m.  The males tend to become mature at length 19.0 m and width of testicles 18 - 20 kg; females - at length 21.0 m.  The pregnant females form 41.3% from mature ones.  The rate of embryo growth is satisfactory described by monoparabola L = 5.98(t - 20.5)1.90The mean new born whale length is 5.5 - 5.6 m.  The peak of two seasons of mating are at May and November, the peaks of births - at April and October.     The pregnancy is 10.5 - 11.0 months long.  The re productivity of pygmy blue whales are low - one new born whales per 2.5 year.},
