چکیده مقاله:

In the present study, the effect of salinity on the body shape was studies in the zebrafish (Aphanius sophiae) using geometric morphometry method. 30 zebrafish at twosalinity levels (0 and 14 ppt) were reared for a month. Then the left side of thespecimens were photographed and landmarks put on two-dimensional images usingtpsDig2. Landmark data after GPA (Generalized Procrustes Analysis) analyzed usingDFA and MANOVA. Results showed significant differences between salinitytreatments (P= 0.0098), so that at low salinity the upper edge of the gill cover, withupper mobility and increase the height of the opening the gill cover, as well as mouthshowed lower mobility mode. Observed changes in high salinity was quite opposite.These results suggest a direct effect of salt on the zebrafish body shape.
