Abstract: The present study was conducted to investigate changes in haemato-biochemical parameters and GSI of Schizothorax niger Heckel during pre-spawning, spawning and post-spawning period in Dal Lake, Kashmir from November, 2014 to July, 2015. Fishes ranging in length from 75-374mm and in weight from 56-557g were taken during the study. The mean values of haemoglobin, RBC, WBC, PCV, MCV, MCH, ESR, Total protein, Total albumin and GSI were recorded as 6.45 g/dl, 2.34×106/mm3, 4.36×104/mm3, 29.86%, 130.68 µm3, 27.78 µg, 3.49 mm/hr, 8.36 g/dl, 5.26 g/dl and 2.02 respectively of the fish during pre-spawning period. During spawning period the mean value of haemoglobin, RBC, WBC, PCV, MCV, MCH, ESR, Total protein, Total albumin, GSI, Absolute fecundity and Relative fecundity were recorded as 4.57 g/dl, 2.35×106/mm3, 7.44×104/mm3, 23.66%, 107.06 µm3, 20.26 µg, 1.58 mm/hr, 3.71 g/dl, 2.72 g/dl, 20.37, 21981 and 109 respectively. During post-spawning period the mean value of haemoglobin, RBC, WBC, PCV, MCV, MCH, ESR, Total protein, Total albumin and GSI were recorded as 6.19 g/dl, 2.56×106/mm3, 5.26×104/mm3, 26.86%, 107.60 µm3, 23.6 µg, 4.06 mm/hr, 8.73 g/dl, 4.53 g/dl and 1.43 respectively. Hb, PCV, ESR, Total Protein, Total Albumin and MCH, MCV were found low in fish during spawning period as compared to pre-spawning (P<0.01) and post-spawning (p<0.05) periods and other parameter such as TEC (p>0.05) did not show any significant difference during the three seasons. TLC, Lymphocyte and Neutrophil were found significantly higher in fish during spawning period (p<0.01) as compared to pre-spawning (p<0.05) and post-spawning periods (p<0.01). Maximum Gonadosomatic Index in Schizothorax niger Heckel were recorded in March, i.e. during spawning period (mean value of 20.37 in females). The GSI then started decreasing gradually and was recorded minimum in July (mean value of 1.43 in females). Thus the peak breeding season of the fish during the present study was found in March. Absolute Fecundity and Relative Fecundity of S. niger were recorded with mean values of 21981.60 and 109.82 respectively. During all periods Hb was found positively correlated with MCH. A negative correlation was found between TEC and MCH, MCV during pre-spawning and spawning periods respectively. A significant positive correlation was found between ESR and GSI at p<0.05 level of significance during pre-spawning period. During post-spawning period MCV was negatively correlated with Total Protein and also a negative correlation was seen between ESR and GSI during this period at p<0.05 level of significance and a positive correlation between ESR and Total Albumin (p<0.05). A positive correlation was recorded between Total Protein and GSI (p<0.05) during pre-spawning period and also between Total Albumin and Absolute Fecundity (p<0.01) during spawning period. A positive correlation was observed between GSI and Relative Fecundity at p<0.05 level of significance during spawning period.
