[ 1 ] - Ultrastructure of the chorion and the micropyle of an endemic cyprinid fish, Cyprinion tenuiradius Heckel, 1849 (Teleostei: Cyprinidae) from southern Iran

 The scanning electron microscope was used to investigate the ultrastructures of the egg membrane surface (unfertilized egg) of an endemic cyprinid fish, Cyprinion tenuiradius Heckel, 1849. The eggs of this species were almost circular in shape, had a smooth surface and one type II micropyle consisting of the flat pit and a long canal in the animal polar region. The micropyle region was not fla...

[ 2 ] - Reproductive biology of Cobitis keyvani (Cobitidae) from the Talar River in the southern Caspian Sea basin

 Some aspects of the reproductive biology of Cobitis keyvani (Mousavi-Sabet, Yerli, Vatandoust, Ozeren and Moradkhani, 2012), an endemic Loach fish species from the Talar River in the southern Caspian Sea basin, in north of Iran was studied by regular monthly collections throughout a year. Fecundity, condition factor, gonado-somatic, modified gonado-somatic and Dobriyal indices were estimated. ...

[ 4 ] - Scanning Electron Microscopy of the scale morphology in Cyprinid fish, Rutilus frisii kutum Kamenskii, 1901 (Actinopterygii: Cyprinidae)

The normal and lateral line cycloid scales of a cyprinid fish Rutilus frisii kutum Kamenskii, 1901 have been subjected to scanning electron microscopy technique to study their detailed structure. The scales have the general morphological characteristics of the cycloid scales. In the normal scale located below the dorsal fin, the focus lies on the anterior region with few mucous pores. There is ...

[ 5 ] - بررسی مقدماتی فون خزندگان منطقه شکار ممنوع کوه گرم جهرم در استان فارس

منطقه شکار ممنوع کوه گرم با وسعت حدود 80000 هکتار در شمال غرب شهرستان جهرم در استان فارس و جنوب ایران واقع شده و از سال 1374 تحت عنوان منطقه شکار ممنوع معرفی گردیده است. فون خزندگان این منطقه از فروردین 1386 تا فروردین 1387 مورد بررسی و مطالعه قرار گرفت. برای نمونه‌برداری از خزندگان، 3 کوادرات در اندازه 100 × 100 متر در ارتفاعات مختلف انتخاب و در مجموع از 225 تله چاله‌ای (چال تله) (pitfall) در ...
