All fishes were sampled by boat trawl, beach seine and trapping barriers. Growth parameters were determined using the monthly length–frequency data. The Mean total length was calculated 8.5±1/35 cm for Common silver-biddy. The value of L∞ and K were calculated 18 cm and 1.5 yr-1 respectively. The rate of natural mortality (M) were estimated 2.68 yr-1. The length-weight relationship were determined as W= 0.0088 L 3.21 and W= 0.00887L 3.21 for Common silver-biddy. Results showed these fishes were juvenile and emphasized on supporting roles of creeks for Gerridae as nursery ground.
