Title

REPRODUCTIVE INDICES OF MALE CASPIAN KUTUM (RUTILUS FRISII) IN GHESHLAGH RIVER (SANANDJ, IRAN)

Pages

  67-78

Abstract

 RUTILUS FRISIIis an endemic fish species of the Caspian Sea basin that have been introduced to Gheshlagh River basin, recently. To understand the reproductive characteristics of transplanted Caspian Kutum to Gheshlagh River basin, twenty male of Caspian Kutum with average 2.1 years old and 133.41 gr (total weight) were caught from Gheshlagh Dam Lake during April to May 2015 by cast net. Some spermatological characteristics; sperm volume, duration of motility, sperm density, spermatocrite, pH and osmolarity of seminal plasma were measured for all sperm samples. The mean values (±SD) for these spermatological characteristics were 2.41 ± 0.16 ml, 42.46 ± 1.07 sec, 17.31 ±2.24 million cells/mm3, 40.8 ± 2.34% and 282.1 ± 4.87 mOsmol/Kg, respectively. The mean gonadosomatic index (GSI) was 5.71 ± 0.31 %. Na+, Cl- and K+ were predominant ionic in the seminal plasma. The concentrations of aspartate aminotransferase (AST), alkaline aminotransferase (ALT), and alkaline phosphatase (ALP) were also measured in the seminal plasma together with serum testosterone and di-hydroxyprogesterone (DHP). AST, ALT and ALP concentration were 48.7 ± 7.29, 16.92 ± 1.57 and 25.4 ± 1.97 U/L respectively. Serum testosterone and DHP concentrations were 1.23 ± 0.24 ng/ml and 0.16 ± 0.04 ng/ml, respectively. Histological study of testes showed spermatozoa were the predominant cells that could be a sign of spermiation stage in male Kutum. Results from our study in comparison with results that obtained by Fallah Shamsi in Sefid Rood River, revealed that habitat changed some reproductive parameters. However, habitat does not have any harmful effect on reproduction capability of Caspian Kutum in the Gheshlagh River basian.
