Fish Species Biodiversity in Kirmir Stream of Sakarya River, Turkey
Abstract
In this study, it was aimed to determine some
diversity indices of fish species in Kirmir Stream of Sakarya River, Central
Anatolia Turkey. Fish samples were caught by electrofishing between November
2006 and November 2007. A total of 9 fish species representing 3 families
Cyprinidae, Cobitidae and Nemacheilidae were recorded. Fish species identified
are as follows: Sakarya chub (Squalius
pursakensis Hankó, 1925), Ankara barbel (Barbus escherichii Steindachner, 1897), Sakarya barb (Capoeta baliki Turan, Kottelat, Ekmekçi
and Imamoğlu, 2006), colchic khramulya (C.
sieboldii Steindachner, 1864), schneider
(Alburnoides bipunctatus Bloch,
1782), Ankara nase (Chondrostoma angorense Elvira, 1987), Sakarya bleak
(Alburnus escherichii Steindachner,
1897), Sakarya spined loach (Cobitis
simplicispina Hankó, 1925) and Angora loach (Oxynoemacheilus angorae Steindachner, 1897). A. escherichii was the most occurence species, constituting 28.77 %
of the total fishes. Shannon-Wiener diversity index (H'), evenness based
on Shannon’s index (J'), Simpson’s diversity index (1-D), evenness based on Simpson’s index (V’) and
dominance index from diversity indices were calculated. The mean indices values
were estimated as 1.67±0.12, 0.77±0.06,
0.76±0.03, 0.86±0.04 and 0.61±0.07,
respectively. S. pursakensis, A. escherichii and O. angorae, included on least concern (LC) species, B. escherichii and C. sieboldii endangered (EN) species, A. bipunctatus vulnerable (VU) species, C. angorense and C.
simplicispina critically endangered (CR) species in the 2014 IUCN Red List
of Threatened Species, were recorded in Turkey.
In the study area, the most important factor threaten sustainability of
the species is considered to be the environmental pollution, agricultural
pollution, metal pollution, habitat loss and drought.
