| Abstract | For the first time, we describe the life-history traits including growth pattern, condition factors including (relativeweight WR), form factor (a3.0), size at sexual maturity (Lm), and natural mortality (Mw) of Gudusia chapra in the MahanandaRiver, Bangladesh. Fishing gears, including gill (fash jal) and push nets (thela jal), were used for sampling during August 2016to July 2017. Body lengths and weight (BW) of each individual were measured. A total of 226 individuals ranging from 6.20-15.10 cm total length (TL) and 2.44-26.10 g BW were collected. On the basis of b value, the growth pattern of G. chapra wasnegative allometric (b<3.0). KF was the best for assessing the overall health of this species. WR was not significantly differentfrom 100 indicating balance population. Also, a3.0 was 0.0062, which indicates that the fish was fusiform in shape. Moreover, Lmand Mw were 9.13 cm TL and 1.14 year-1, respectively. These results should benefit shad management. |
