یافته علمی کوتاه: کاریولوژی ماهی خیاطه (Alburnoides bipunctatus) منطقه زابل

The chromosomal spread and karyotype of spirlin (alburnoides bipunctatus) from zabolregion were identified using tissue squashing techniques with injection of 0.5ml/100g bodyweight of 0.01% colchicines solution in fish fingerlings. kidney and gill tissues wereextracted and chopped in kcl 0.075m for 30 min and fixed in carnoy solution in 3 stages.the chromosomal spreads were stained in 20% gimsa for 20 min. from 34 chromosomalspread counts, the results showed diploid chromosome number of this species 2n=50.karyotype composed of 9 metacentric, 14 submetacentric and 2 acrocentric or subtelocentricchromosome pairs, and the number of chromosome arms (nf) was determined as nf=96
