“…This is in tandem with findings of Rabiu et al (2018) who obtained higher total dissolved ions during the dry season relating it to dissolved materials and rise in amount of dissolved solids. Similar observation in high TDS was also reported by Abubakar and Abdullahi (2015) in Jakara Dam, Kano. Turbidity in Jakara Reservoir varied significantly between the sampling sites and it did not indicate any significant difference among the sampling sites.…”

The risk of heavy metals bioaccumulation in gills and liver of C. gariepinus of Jakara Reservoir, Kano was assessed for period of twelve months (March, 2020 to February, 2021). In situ and in vitro examinations were performed using standard procedures. Sites for sampling were categorized into three as offshore (A), midshore (B) and inshore (C) were chosen based on the impact of varying humans activities within the reservoir. The mean range of physicochemical parameters were water temperature (27.1 – 28.30 °C), Dissolved Oxygen (5.9 – 6.6mg/L), Biological Oxygen Demand (2.4 – 3.7mg/L), transparency (0.9 –1.2m), electrical conductivity (637.1– 1064μS/cm), pH (7.8 – 8.1), and Total Dissolved Solids (433.1–733.8mg/L).Gills had accumulation of Fe, Cr, Cu, Pb and Cd in a concentration graded fashion with Fe being the highest and Cd the lowest in terms of concentration. BAF in liver tissues recorded a decrease in the following sequence: Cu >Cr> Pb > Fe >Cd. Physicochemical parameters, heavy metals bioaccumulation differed significantly (P<0.05) between the sites and seasons with the exception of TDS, EC, turbidity and Cadmium. It can be deduced that fluctuation in water quality parameters and heavy metals concentrations in the reservoir could be attributed to high influx of nutrients due to farming activities among other anthropogenic input. It is hereby recommended that indiscriminate discharge of agro chemicals among other domestic inputs should be minimized in order to curtail degradation of the reservoir in the long run. Relevant authorities should develop strategies to control potential effect of the pollutants on the aquatic biota in the water body.

“…According to Belcher and Swale (1972) A. vegetans is widely distributed, and literature searches revealed its presence in the freshwaters of most continents, including Europe, Asia, North and South America, and Australia (Figure 1). In Africa, it has been recorded only once before, in the Jakara Dam in Nigeria by Abubakar and Abdullahi (2015). No records could be found of this species' presence south of Nigeria on the African continent.…”

“…Anthophysa vegetans is well documented from all continents, except Africa, where it has been recorded only once in the Jakara Dam in Nigeria (Abubakar & Abdullahi 2015), and Antarctica with no known record. Unidentified members of the genus Anthophysa were recorded in the Klip River, South Africa, by Hancock (1973), as well as in and around Kirstenbosch National Botanical Garden in Cape Town by Joska et al (2005).…”

Background: Although the colonial flagellate alga Anthophysa vegetans is well known in Europe, it has only been recorded from Africa (Nigeria) once. It was recently found in the Mooi River, South Africa – making this a first record of the presence of A. vegetans in southern Africa. Objectives: The objective of this study is to record a new geographic locality for A. vegetans for South Africa. Method: Light microscopy was used to compare morphological features of the species found in South Africa with illustrations and literature on A. vegetans found in Europe and other countries of the world. An extensive literature survey was done to determine the species’ current geographic distribution. Results: A. vegetans is widely distributed across all continents, except Africa and Antarctica. During this study, it was described from a new location in the Mooi River near Potchefstroom in the North West province, South Africa, making this a first record of its presence in southern Africa. Conclusion: The known geographic distribution of A. vegetans was expanded to include southern Africa and, to be more specific, South Africa.
