Temporal Variability and Predictors of Fish Catch (2009-2011) in the Niger and Benue Rivers: Implications for Contemporary Natural Resources Management in Kogi State, Nigeria
Keywords:

The Niger and Benue Rivers are critical to the livelihoods of communities in Kogi State, Nigeria, particularly in the fishing industry. However, fish catch variability due to environmental and anthropogenic factors poses significant challenges to sustainability. This study examined fish catch variability in the Niger and Benue rivers, Kogi State, Nigeria, from 2009 to 2011. Results revealed significant seasonal fluctuations, with average catches ranging from 26.7 to 50.2 units during the study period. Environmental factors, such as temperature (r = 0.999) and river flow rates (r = -0.999), were strongly correlated with fish catch variability. Anthropogenic activities, including dam construction and pollution events, also impacted fish populations. The study emphasizes the need for sustainable fisheries management, including adaptive strategies, environmental monitoring, mitigation measures, community engagement, and climate change adaptation. By understanding the complex interplay of environmental and human factors, effective management plans can be developed to ensure the long-term sustainability of fish populations and the livelihoods of dependent communities.
