The Effect of Preservation in Alcohol on The Morphological Characters of The Zagros Tooth-Carp, Aphanius vladykovi Coad, 1988

The present research was performed to investigate the effects of fixed and preserved in 96% alcohol on the morphological characteristics of the Zagros pubfish, Aphanius vladykovi Coad, 1988. For this purpose, 30 specimens of A. vladykovi were collected from rivers in Chaharmahal-o-Bakhtiyari Province, Iran. After an initial evaluation on morphological characters (TL, SL and HL), Samples were fixed and preserved in 96% alcohol for 3 months. After this period, samples were removed from the alcohol and then measurement and evaluation of color features were performed once again. The results indicated that shrinkage was common in all the specimens and changes in body color were clearly distinguishable compared with fresh fish such a way that the body and fin colors were opaque, while color pattern was detectable, although the intensity was reduced.
