Abstract

Length–Weight Relationships of Twelve Fishes from the River Padma near Rajshahi City, Bangladesh

Golam Mortuza M and Fahad A. Al-Misned

The objective of this study was to evaluate the length-weight relationships (LWRs) of freshwater fish species, which serves as a baseline for comparison to other relatively altered tropical Bangladeshi rivers. The LWRs of 12 species belonging to four classes, seven families and 11 genera (Gagata youssoufi, Cirrhinus reba, Clupisoma garua, Ompok bimaculatus, Pangasius pangsius, Securicula gora, Ailia coila, Chanda nama, Parambassis ranga, Botia lohachata, Rhinomugil corsula and Labeo boga) captured from the River Padma near Rajshahi City, Bangladesh, were studied. The allometric coefficient (b) of the LWRs indicated positive allometric growth in P. pangsius, A. coila, C. reba, B. lohachata and C. nama (b>3.00), but negative allometric growth in G. youssoufi, C. garua, O. bimaculatus, S. gora, P. ranga, R. corsula and (b<3.00). The results would be useful for sustainable management and conservation of the limited stocks in the Padma River ecosystem.
