Length-weight and length-length relationships of some small indigenous fish species from the Mathabhanga River, southwestern Bangladesh

Abstract

The present study describes the length–weight (LWR) and length–length (LLR) relationships for eight important small indigenous fish species (SIS) from the Mathabhanga River, southwestern Bangladesh, namely Amblypharyngodon mola (Hamilton, 1822), Channa punctata (Bloch, 1793), Hyporamphus quoi (Valenciennes, 1847), Macrognathus aculeatus (Bloch, 1786), M. pancalus (Hamilton, 1822), Nandus nandus (Hamilton, 1822), Puntius sophore (Hamilton, 1822), and Setipinna phasa (Hamilton, 1822). A total of 2543 specimens used for this study was caught by traditional fishing gear from January to December 2005. To the best knowledge of the authors, this study presented the first reference on LWR and LLR for these species from Bangladeshi waters.
