Vertical and seasonal distribution of phytoplankton in the Shen Reservoir Plateau State, Nigeria.
In: 4th Annual Conference of the Fisheries Society of Nigeria (FISON)
, 26-29 November, 1985
, Port-Harcourt, Nigeria.
The phytoplankton distribution of the Shen Reservoir, Bukuru in the Jos Plateau, Nigeria was monitored at 6 depths. Higher floral abundance occurred within the upper 00-03 meters with highest values at the first 1 meter. Bacillariophyceae and Dinophyceae recorded higher values in March-April with lower values in July and January respectively. Phytoplankton were most abundant in the rainy season. Secchi disc transparency was lowest in the peak of the rainy season (July) due to higher levels of suspended matter resulting from the increased run-off from surrounding farmlands of allochthonous materials as well as higher levels of phytoplankton population arising from the former factor. The low water temperature of December/January 15 degree C plus or minus 2 degree C might have depressed growth among the major groups of plankters but enhanced rapid multiplication of the Chlorophyta, Trachelomonas which showed a bloom at this season
