Title: The effect of anthropogenic activities on fish composition and diversity of river Chanchaga in Niger State, Nigeria Authors: Ibrahim, S.U; Adejola, Esther O; Amanambu, Onyediku P Abstract: Fish species composition and diversity of River Chanchaga which is located in theSouthern part of Niger state, Nigeria were studied. The sampling was conducted for a period of 4months, 20 species from 8families were identified. These families are Bagridae, Clariidae, Cichlidae, Characidae, Claroteidae, Mochokeidae, Malapteruridae and Mormyridae. The total catch for all species during the sampling period was 282, Cichlidas were the most dominant with total catch of142, while Bagridae had the lowest 'diversity with total catch of 3. On the monthly fish species, the result indicated that August had the highest composition and diversity 7.190±7.520°while June had the lowest of 5.714 ± 13.330a Therefore, there is need for effective monitoring and conservation strategies to ensure sustainability of the River.

Title: WATER QUALITY ASSESSMENT OF THE PROPOSED KWADNA RESERVOIR WITHIN GIDAN KWANU MAIN CAMPUS, FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, NIGER STATE, NIGERIA Authors: Ibrahim, S. U; Ibrahim, A.,; Yusuf, J.,; Adama, S. B.,; Abdulmumini, A.N. Abstract: The study assessed the Water Quality parameters of the Kwadna Reservoir located at Federal University of Technology, Minna guided by the following objectives: determine the variation of the physico-chemical parameter across the months, the stations and to provide baseline data of the various physical and chemical properties of water. The Physico-chemical parameters of the river were studied for twelve weeks. Water samples was taken from five (5) stations in the reservoir, biweekly for the period of study. Samples collected was taken to the department of Water Resources, Aquaculture and Fisheries Technology (WAFT) laboratory for analysis. The results of the research depict that there was no significant variation in the mean values of physico-chemical parameters observed across the Station (p>0.05), pH range from 7.05±0.03 -7.36 ±0.03, Conductivity 281.5±45.5-311.7±44.9 μS/cm, Total alkalinity 115.7±22.0 -174.0±18.9, Total hardness 48.1±9.5-57.4±11.3mg/L, Calcium 17.3±5.4-24.6±4.6mg/L, Magnesium 4.0±2.4- 8.6±2.9 mg/L, TDS 177.2±28.3-199.3±28.9mg/L,BOD 2.7±0.1-3.1±0.4mg/L, Dissolved oxygen 4.9±0.6-5.7±0.1mg/L, Carbon dioxide 1.7±0.9-3.4±2.3mg/L, BOD 2.7±0.1-3.1±0.4mg/L. Except Temperature and COD that has significant difference (p<0.05) range between 27.0±0.0- 28.5±0.50C and 18.1±2.8-104.9±45.9 mg/L respectively. For monthly variations most parameters had significant difference (p<0.05) except Temperature and BOD that has no significant difference (p>0.05). Most of the physico-chemical parameters studied were within WHO range set standard for optimal fish production and survival. The mean temperature of the Reservoir (29.46°C) is in line with FAO (2006), which states that temperature requirements of 250C–300C is optimum for fish growth. This shows that temperature in the proposed Kwadna Reservoir is suitable to support the growth of fish Therefore, constant monitoring of the reservoir should be encouraged.

COMPARATIVE ASSESSMENT OF LANDUSE LANDCOVER CHANGES ON WATER QUALITY OF RIVER KADUNA FROM 2012-2020 AT WUYA, NIGER STATE, NIGERIA

Title: COMPARATIVE ASSESSMENT OF LANDUSE LANDCOVER CHANGES ON WATER QUALITY OF RIVER KADUNA FROM 2012-2020 AT WUYA, NIGER STATE, NIGERIA Authors: Ibrahim, S.U.; Dania, M.O.; Yusufu, F.O; Kolo, R.J; Sadiku, S.O.E. Abstract: The study investigates the effects of land use land cover changes on water quality of River Kaduna from 2012-2020 at Wuya, Niger state, Nigeria using Landsat 7 imagery. Five classes of LULC types where selected and used as basis for classification. Also, five (5) sampling stations selected on the water body for water quality analysis which were collected once monthly for a period of six months from February 2020 to July 2020. The results of LULC classification depicts an increase in water body from 2.241km2 in 2012 to 3.029km2 in 2020 while Agricultural areas increased drastically from 4.718km2 in 2012 to 22.862km2 in 2020. Physical and Chemical parameters showed range values of Total dissolved solids varying from (15.54±18.00 - 61.00±21.38) in 2012 while (3.67±1.05 - 5.67±2.57) in 2020, Alkalinity was between (31.33±8.08 - 62.33±17.79) in 2012 whereas (21.33±11.55 - 29.33±6.11) in 2020, Hardness ranged from (38.67±4.16 - 51.33±10.26) in 2012 whereas (15.00±1.73 - 22.33±7.77) in 2020. The result showed no significant difference (p > 0.05) except Total dissolved solids, Alkalinity and Hardness which recorded higher values on both seasons across stations and months. In general, the study revealed increase in agricultural area drastically, so there is a need to constantly monitor and update the check list of land use land cover, Physical and Chemical parameters changes in and around the River to control anthropogenic pollution from residence, on the water and from nearby farmlands.
