In the present research, an attempt was made to study the seasonal variations in spleen somatic index (SSI) of Garra gotyla gotyla. Fish Garra gotyla gotyla selected for the present studies, were collected from the Jhajjar stream at Jhajjar Kotli one of the tributaries of river Tawi situated at an elevation of 400 meters above the mean sea level (msl) and is 34Km from Jammu on NH1A to Kashmir, the study was carried out from November,2009 to October, 2010. The lowest value of SSI was recorded during the summer season (0.150) and highest was observed during winter season (0.330). SSI exhibits an inverse relation with gonado somatic index (GSI) and total leucocyte count (TLC). The peak value of GSI was recorded during the summer season (9.31) whereas lowest value of 0.40 was noted during winter season. In similar manner TLC was highest during summer season (17.21×103/cmm) and lowest during winter season (14.29×103 /cmm).
