“…The present mean values of TL and BW are higher than the values for A. jaya (2.75-7.81 cm and 0.14-3.67 g, Kaushik et al, 2015) relative body weight; n, specimen size; ns, not significant at any level; **, highly significant at 1% level (p < 0.01); *, significant at 5% level ( p <0.05) Table II. Spearman rank correlation coefficient (rs) for condition factors (Fulton's condition factor and relative body weight) with lengths (cm) and body weights (g) of five fishes in the Atrai River, Dinajpur, Bangladesh due to geographical variation but are within the limits for G. cenia (5.50-6.65 cm, Chaki et al, 2013), S. bacaila (3.40-15.20 cm, Masud andSingh, 2015) and S. phulo (6.00-10.70 cm and 1.36-7.21 g, Siddik et al, 2016), respectively. As there is a first record on length and body weight of G. youssoufi in the Atrai River (Islam and Mia, 2016), so no comparison was possible against this value with the previous one.…”

For evaluation of Fulton's condition factor (CF f ), relative body weight (BW r ) and form (a 3.0 ) 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 CF f (0.47-1.56) but not for BW r (79.60-128.39). Based on CF f 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 CF f and BW r , G. youssoufi showed good health condition (CF f = 1.22±0.01; BW r = 100.63±0.79) and were separated (stress = 0.0003) from other fishes. Lowest a 3.0 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.

“…The growth coefficient value b normally lies between 2.5 and 3.5 (Carlander, ; Froese, ) and this value of all three species in the present study was within the expected range as well as within the 95% confidence limits of the Bayesian LWR predictions value in Fishbase (Froese & Pauly, ). Thus, the b value of the same fish species differed with the length range used, sampling sites and season, stomach fullness, gonadal maturity, sex, diet and environmental (Islam et al., ; Siddik, Hanif, Chaklader, Nahar, & Fotedar, ; Siddik, Chaklader, Hanif, Islam, & Fotedar, ; Chaklader et al., ). The co‐efficient of determination ( r 2 ) values narrated the proper fitness of the model for growth (Datta, Kaur, Dhawan, & Jassal, ) and fish with ideal growth always shows co‐efficient of determination between 0.9 and <1.…”

Summary The present ichthyological report describes the length‐weight relationships (LWRs) of three catfish species (Eutropiichthys murius, Nangra nangra and Gagata viridescens) belonging to two families from the Kaliganga River, a tributary of the Dhaleshwari River, Bangladesh. The analyses included 306 specimens collected monthly from fishermen's catches during October 2015 to April 2016. Ranges of regression parameters a and b of the three species were within 0.0058–0.0099 and 2.900–3.142, respectively with highly correlated coefficients of determination (r2 > .995; p < .001). The LWRs for all three species presented herein for the first time with a new maximum length record for N. nangra.

Sandha River water regime is used as a nursery, feeding and breeding places by commercially important fish species due to the presence of unique environment. Therefore, the present study has been conducted to assess water quality parameters, fish species abundance, fish diversity indices, conservation issues and management policy to guard the valuable aquatic resources of Sandha River from March 2015 to February 2016. Among the water quality parameters, temperature and pH were found at a slight rising level which possessed insignificant negative correlation with fish species abundance (p<0.01). Fish diversity indices were calculated of which the value of Shannon-Wiener Index just above 3 which indicated the river ecosystem still approving good fish community structure where lower value of richness described short food webs. Garretts Ranking Technique was applied to identify the reasons behind the decline of Sandha River fish species over the periods. The study, therefore, concluded that the river has experienced with slight climate modifications and significant anthropogenic activities especially huge fishing pressure which in a feedback reduce the fisheries stock resources with time. Community-based fisheries management (CBFM) hence would be an appropriate tool to make the water resources sustainable.
