Some aspects of reproductive biology of gangetic ailia, Ailia coila (Hamilton, 1822) in Bangladesh

In the case of length weight relationship (LWR), the coefficient of determination value (r2 ) was found 0.96 and the slope was found b = 1.50 which indicated the pattern of negative allometric growth of this species as b < 3. In contrast, an increase was recorded in the fecundity associated with the rise of total length, body weight and gonad weight showed a significant linear relationship. This study would assist in the development of induced breeding techniques and provide valuable information for the sustainable management of this population in the inland open ecosystem.
