Abstract


Present study was undertaken to investigate fish potential from Karez Sarawan, Balochistan. In total 2694 specimen of different fish species were collected ranged between 5.5 to 13.08cm and 0.9- 22.06g respectively. It was observed that the fish potential of Karez Sarawan consists of 3 families, 4 genera and 7 species namely Cyprinion watsoni, Channa striata, Labeo buggut, Labeo bata, Schizothorax sp: Aphanius ginaonis, Aphanius dispar. Among the species Cyprinion watsoni was considered as the most abundant and constitutes about (70.68%) followed by Schizothorax sp and Labeo buggut (11%) of the total catch. The lengthweight relationship values of the above fish were calculated and observed from the equation that Labeo bata found to be in ideal condition, C. striata, C. watsoni and Labeo buggut found in satisfactory growth respectively and poor growth was noticed in case of Schizothorax sp. from Karez Sarawan. The Simpson’s biodiversity index (1-D = 0.481) shows that the Karez has low ichthyic diversity. It is an intense need to monitor water quality parameters regularly and stock fish in the Karez to improve and enhance the diversity. Finally it was concluded that the environment of Karez Sarawan favors the potential of economically important carp L. bata.
