Abstract

For evaluation of Fulton’s condition factor (CFf), relative body weight (BWr) and form (a3.0) factor affecting growth, 5 fishes (Aspidoparia jaya, Gagata cenia, G. youssoufi, Salmophasia bacaila and S. phulo) were collected from the Atari River in Dinajpur district of Bangladesh. Significant differences (p < 0.05) were recorded among the values of CFf (0.47-1.56) but not for BWr (79.60- 128.39). Based on CFf values, analysis of similarities (ANOSIM, p < 0.01) revealed that maximum distances (R = 0.9946) were found between G. youssoufi and S. bacaila while lowest (R = 0.2175) between G. cenia and S. phulo. Using two-dimensional nMDS scaling of CFf and BWr, G. youssoufi showed good health condition (CFf = 1.22±0.01; BWr = 100.63±0.79) and were separated (stress = 0.0003) from other fishes. Lowest a3.0 value was noted for S. bacaila (0.004) and highest for G. youssoufi (0.012). Therefore, G. youssoufi showed healthier and former body with more adaptability in this river than those of others. These are the first records for proper management of above mentioned fish species and future research in the near future.
