Life-history traits of the freshwater garfish xenentodon cancila (Hamilton 1822) (Belonidae) in the Ganges River, Northwestern Bangladesh

The freshwater garfish, Xenentodon cancila (Hamilton 1822), is one of the commercially important, nutritionally valuable food fish in Asian countries, but the natural populations are seriously decreasing due to high fishing pressure and other factors. This study describes the life history traits, in...
