The present study describes the length-weight (LWR) and morphometric relationships of the tank goby Glossogobius giuris (Hamilton 1822) (Perciformes: Gobiidae) an important small indigenous fish species in the Ganges northwestern Bangladesh. A total of 266 specimens 11.30-23.60 cm in total length (TL) were caught using traditional fishing gear from March 2006 to February 2007. The allometric coefficient b of the LWR for the combined sexes was close to the isometric value (b 3.068 for TL and b 3.089 for SL standard length) but with a slight negative allometric growth for males (b 2.954 for TL b 2.953 for SL) and a slight positive allometric growth for females (b 3.293 for TL b 3.166 for SL). The results further indicated that morphometric relationships were highly correlated (r 0.712; P 0.001). To the best of our knowledge this study presented the first reference on LWR and morphometric relationships for G. giuris from Bangladeshi waters. These results will be useful for fishery managers to impose adequate regulations for sustainable G. giuris fishery management not only in the Ganges of Bangladesh but also in neighbouring countries.

Abstract

The present study describes the length-weight (LWR) and morphometric relationships of the tank goby Glossogobius giuris (Hamilton 1822) (Perciformes: Gobiidae) an important small indigenous fish species in the Ganges northwestern Bangladesh. A total of 266 specimens 11.30-23.60 cm in total length (TL) were caught using traditional fishing gear from March 2006 to February 2007. The allometric coefficient b of the LWR for the combined sexes was close to the isometric value (b 3.068 for TL and b 3.089 for SL standard length) but with a slight negative allometric growth for males (b 2.954 for TL b 2.953 for SL) and a slight positive allometric growth for females (b 3.293 for TL b 3.166 for SL). The results further indicated that morphometric relationships were highly correlated (r 0.712; P 0.001). To the best of our knowledge this study presented the first reference on LWR and morphometric relationships for G. giuris from Bangladeshi waters. These results will be useful for fishery managers to impose adequate regulations for sustainable G. giuris fishery management not only in the Ganges of Bangladesh but also in neighbouring countries.
