Primary production and some limnological aspects of Nasarawa reservoir Katsina, Nigeria


Author(s): Zahraddeen Hassan Yusuf, Isiyaku Ibrahim Indabawa and Babangida Abdulkarim

Abstract: Primary production, and some limnological aspects of Nasarawa reservoir was investigated from February to November, 2018 weeks to ascertain the health of the reservoir’s ecological system. Sampling was conducted on five sites near the dam wall on a monthly basis, at a one meter interval depth profile. The phyico-chemical parameters were analysed using standard techniques. Dark and light bottle dissolved oxygen method was employed for the analysis of Net primary productivity, Gross primary productivity and Community respiration. pH, temperature, conductivity, transparency, dissolved oxygen, nitrate nitrogen, phosphate phosphorus and net primary productivity shows seasonal variation while biochemical oxygen demand and community respiration showed no seasonal variation. The parameters analysed were higher in dry season. Net primary productivity and gross primary productivity was highest in site C while community respiration was highest in site E. The low productivity of the reservoir in the wet season might be due to high suspended solids in the flood water which restrict light penetration into the reservoir and thereby results in less photosynthetic activities. Primary production in Nasarawa reservoir in all the stations was probably because of the rate of photosynthesis caused by seasonal fluctuations in water temperature, transparency and nutrients experienced.
