Comparative analysis of age and growth of Oreochromis Nilotic’s in the Yamuna and Ganga Rivers

Abstract

This study presents a comparative analysis of the age and growth characteristics of Oreochromis niloticus populations from the Yamuna and Ganga Rivers in India. Utilizing scale-based age determination methods and evaluating growth rates, we identified significant differences in growth trajectories and age distributions between these populations. The results highlight the influence of environmental conditions and habitat characteristics on fish growth, underscoring the necessity for region-specific management strategies to promote sustainable fisheries.
