The inlandwater resourses are including;lakes,wetlands,rivers ,springs and qanats. The qanat is the water or channel through which water flows from the depths of the earth to its surface. Over the past two decades, studies have been done on the  inlandwater resources by writers of this article and other reseachers. The results of the studies showed that 22 fish species belonging to 5 family comprising of   Syprinidae, Poeciliidae, Nemacheilidae, Cyprinodontidae and Channidae have been  identified . Among them 6  species including, Aphanius dispar, Chaana gachua, Paraschistura kessleri,،Garra rosica , Garra persica and Garra rufa are suitable to introduce as aquarium fishes.

In order to some morphometric and meristic study of capoeta fusca Nikolskii, 1897 in Qanats of Ferdows city during 2010 to 2011, 90 specimens were collected of three Qanats in Ferdows city. Specimens after fixation in 10% formalin, were transferred to the Razi laboratory of Ferdows city and identiffed by identification key. The maximum and minimum of Total length for C. fusca of Ferdows city Qanats were 19.6 cm and 3/02 cm. The results showed in this species there is in the Dorsal fin 3 unbranched ray and 7 branched ray, in Anal fin 3 unbranched ray and 5 branched ray, in Pelvic fin 1 unbranched ray and 8 branched ray and in Pectoral fin 1 unbranched ray and 16 branched ray. Also were counted, lateral line scales 45 to 53; Above the lateral line scales 8-9, Bottom the lateral line scales 7. The relationships study for this species showed between Total length- Head length, Total length- Body Depth and Head length- Body Depth, is a positive and significant correlation and have are. /99 of correlation coefficient. Also, in The statistical comparison of morphometric and meristic characters of specimens between three locations by F-test, were not significantly different(P>0/05).

In order to identify the fishes of Qanats in Birjand area located in north-east of Iran, a series of sampling were carried out during 2001-2002, with covering 44 Qanats. The samples were collected by net and after fixation in 10% formaline, they were transferred to laboratory for further precise identification.
At the end, there were found only 2 species of Capoeta fusca and Garra rossica belong to Cyprinidae family. Also, some samples were sent to Canada for attesting the identifications.
It was found that the Capoeta fusca is an endemic species and geographically is only found in eastern part of Iran.
