Study of testis morophocytological indexes of Benni (Barbus sharpeyi) in Shadegan Wetland
In this study, histological characteristics of testis in Barbus Sharpeyi at different stages were investigated. Fishes were collected from February 2008 to Shadegan Wetland. Testis of 40 fishes were sampled and fixed in Boun solution. Samples were processed through standard histological method and studied under light microscope. Following eight maturity stage was observed: Immature, Immature developing, Developing, Developed, Mature, Prespermation, Spermation, Reabsorbtion. Diameter of testis sexual cells were calculated in immature testis 40 micron, spermatogonium cells 35 micron, primary spermatogenes cells in during evolution 30 Micron, primary spermatogenesis cells in during evolution 30 Micron, Evaluated middle spermatogenoces cells 25 Micron and final rip spermatogenesis 10 Micron.
