ABSTRACT

 This study was designed to assess the population status of Oncorhynchus mykiss (Rainbow trout), Salmo trutta (brown trout) and Schizothorax plagastimous (swati fish) in river Swat. Data were collected from four subareas (SAs) namely Madyan (SA1), Mankiyal (SA2), Kalam (SA3) and Mahoo Dhand (SA4). Fishes captured with electrofisher were identified morphologically and the wet weight and body length were determined. A total of 502 fishes were captured and identified. The highest capture (206) was recorded at SA4 whereas the lowest (64) at SA1. Similarly the highest captured specie (276) was Salmo trutta while the lowest (22) was Schizothorax plagastimous. The body length ranged from 15-36 centimeters whereas the wet weight varied from 47-304 grams. Out of 502 fishes, 64, 104, 124 and 206 were from SA1, SA2, SA3 and SA4, respectively. The mean wet weight of Oncorhynchus mykiss, Salmo trutta, and Schizothorax plagastimous 137.15g, 124.57g  and 138.85g, respectively. The aim of the study was to determine species-wise, size-wise and sex-wise relative abundance of fishes in river Swat.
