SUMMARY

 

Hallajian A, Yousefi Jourdehi A, Kazemi R, Yarmohammadi, M., Sexual maturation of male and female gonads of cultured Beluga (Huso huso), Onl J Vet Res., 20(5):362-370, 2016. Sexual development in fish can be determined through gonad biopsy and microscopy. Twenty four farmed 5 yr old Huso huso gonads were biopsied and subjected to microscopy. Fourteen (58.3 %) were females and 10 (41.7 %) males. In females 7.1% were stage I maturation, 64.3% stage II, and 28.6% stage II-III. In males 40% were stage II, 10% stage III, 20% stage III-IV and 30% sexual maturation stage IV. Results suggested that at same age, males matured sexually earlier than females

 

Key words: Farmed Huso huso, Gonad, Biopsy, Sexual maturation stages.
