Abstract: The distribution of Daphniopsis tebitana Sars in Xizang inland saline lake and its biological parameters in the experimental population were investigated. D. tebitana are widely found in saline lakes in northern Xizang Region, where the temperature ranged from
–2℃ to 20℃ , salinity varied from 9 to 35, and pH ranged from 9. 0 to 10. 4. D. tebi-tana lives in the plateau lakes which altitude is more than 4000 m. Life expectancy in salini-ty 16～ 17(Lake Namukacuo), 22～ 25(Lake Namukacuo) and 31～ 32(Lake BangeⅢ) groups were 48. 00± 12. 60, 44. 60± 14. 20 and 55. 10± 9. 70 d, respectively; the maximum life expectancy was 69,68 and 72 d; the average preceding duration of procreation was 21. 33± 1. 41, 23. 25± 3. 38 and 22. 34± 3. 76 d; and the average interval of each procreation was 7. 55± 1. 48, 8. 07± 1. 82 and 7. 88± 1. 88 d; the number of each procreation was 8. 86± 1. 47, 7. 67± 2. 19 and 6. 82± 0. 81 ind.;and the max- imum of each procreation was 17, 15 and 9 ind.; cumulative production of young was 24. 33± 15. 78, 19. 33± 7. 00 and 20. 50± 5. 67 ind.; its maximum production was 59,37 and 33 ind, respectively. The exploitation and use in marine aquaculture of D. tebitana was discussed.
