Breeding techniques

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.

Common carp is one of the most important cultured species in Vietnam. The goal of the carp breed program was creation of a common carp breed with stable genetic qualities such as fast growth, high survival rate and attractive appearance. In the first phase (1981-1985) the program focused on the assessment of the original carp varieties, which should be used as initial materials for selection.
