    (Department of Zoology, Faculty Of Natural And Applied Sciences, Nasarawa State University, Keffi, 2020-01-13) Cheka, B.C.; Banyigyi, A.H.; Ameh, S.M.
    Analysis ol the stomach contents of Barbus occidental is from River Uke, Nasarawa Slate, Nigeria was studied using 219 Barbus occidentals samples collected between March - August 2017. Food and feeding habit of the sample was done using numerical, frequency of occurrence and volumetric methods. The result showed that the fish fed mostly on phytoplankton (Cyanophyceae (15.84%), Chlorophyceae (12.29%), Filamentous algae (1.09%), three groups of zooplankton encountered were copepods (0.41%), cladocerans (5.56%) and nematode (20.94%), and they also fed substantially on anthropods (7.16%), fish remains, insect larval (1.19%) and benthos organisms (5.68%), the study indicated that the fish is omnivores. There was no significant difference (p>0.01) on the item consumed in wet and dry seasons. The information gathered from this present study serves as a guideline for further research on the river

    ASSESSMENT OF HEAVY METALS IN WATER CONTAMINATED WITH PETROLEUM PRODUCTS IN KEFFI LOCAL GOVERNMENT AREA, NASARAWA STATE, NIGERIA
    (Department of Zoology, Nasarawa State, University Keffi, 2019-08-08) Makpo, James Kpuk; Ameh, S.M.; Gambo, Y.P.
    This work assessed the presence of heavy metals in water contaminated with petroleum products in Keffi Local Government Area. Two water sampling stations were selected based on the stratified method of sampling of Antau River. Station A was located along Federal Government College Keffi popularly known as Antau Bridge where Agricultural and mechanical activities, with sales of petroleum product took place. Station B was located at Dadin-Kowa known as Gadamanu where human activities such as bathing and washing took place which served as control. The distance between stations is 1km. The procedural plan of this study was monthly sampling of water from both Stations. Materials such as funnel, sampling container, distilled water, conical flask, filter paper, 50ml polypropylene centrifuge tube, cooler were used. Heavy metal concentrations were determined using X - ray Fluorescent Spectroscopy (XRF) at the Center for Energy Research and Training (CERT), Ahrnadu Bello University Zaria. The water parameters of the four samples were determined using the Extech instrument. The result on Physico - chemical parameters revealed the values obtained from contaminated water samples to be pH (7.31), Dissolved Oxygen (1.14), Electrical Conductivity (8.22), Total Dissolved Solid (4.13), Temperature (27.45) and Salinity (0.091) while the controlled Station at point B were pH (7.43), DO (7.35), EC (3.14), TDS (1.54), Temperature (26.75), Salinity (0.094) respectively. From the result obtained, the heavy metal contaminated samples had the following values: Mg (29.3ldb), A1 (218.69±), Si (230.12±), S (1153.65±), Cl (54.25±), Ca (106.56±), Ti (23.66±), Cr (3.15±), Fe (15.92±), Cd (7.54±). For the control sample at point B, the following values were obtained: Mg (27.49±), A1 (223.71±), Si (243.21±), S (94.84±), Cl (23.52±), Ca (28.44±), Ti (32.99±), Fe (16.63±), Cd (7.67±) respectively. The P-value was 0.8105 (p>0.05) for the water quality parameters while for the concentration of heavy metal P-value was 0.2054 (p>0.05), which indicated a non significant difference between the concentrations of elements. However, the concentration values of heavy metals in the contaminated water at Station A and control water samples at Station B were higher than the World Health Organization values (Standard) for drinking water

    GILLS AND INTESTINAL PARASITES OF MORMYRUS RUME AT UKE RIYER, KARU LOCAL GOVERNMENT AREA, NASARAWA STATE, NIGERIA.
    (Department of Geography, Nasarawa State State University Keffi, 2020-01-06) Banyigyi, A.H.; Akpanwa, Y.R.; Makpo, James Kpuk; Ameh, S.M.
    30004 and farm *51 are potential host of various parasitic species that cause grater mortalities. The normal of fish is affected by the parasites that lives on the fish if highly infested, Mormyrus mme are increasingly becoming important in the aquarium business and aquaculture, thus the need arises for a better knowledge about the nature and control of parasites affecting them. Total of one hundred and ten (110ر samples of different sizes of Mormyrus هاذا were collected at different dates at Uke River. Kam Local Govermneni Area of Nasarawa State between July and September2O19 from local fishermen. The fish were transported in a cooler containing ice to the Zoology Labouratory of Nasarawa State University, *•05 for gills and intestinal parasites examimatiori. Forty-two (42) were found to infected with parasites and the total of number of parasites recovered were sixty-nine (69). Parasites isolated were Eimeria ولحلآى, Procamdmis spp, 50, D. latum and B. daviceps. Apart from Eimeria spp that recovered from gills the rest parasites were recoverd from the instestine. The highest number (50) of parasites species isolated was Procamallan spp, followed by Dactylogyrus spp (9) while Eimeria spp and B. claviceps parasites isolated were four (4) each and the lowestnumber(2) ofparasites isolated wasD. latum. Continue study on the parasites of other fish in Uke River is recommended to provide knowledge on the parasitic infestationlevel ofthe fish in the River.

    GROWTH PERFORMANCE AND FEED UTILIZATION OF CATFISH (Clarias ga 7epinus) FINGERLINGS REARED IN STRUCTURED AND UNSTRUCTURED WATER
    (Department of Zoology, Nasarawa State University Keffi, 2018-01-06) Ameh, S.M.; Makpo, James Kpuk; Sotolu, A.O.; Banyigyi, A.H.; Cheka, B.C.
    This study dett 'mined the growth performance and feed utilization of catfish (Clarias gariepinus) fingt lings reared in structured and unstructured water (de-clorinated tap water). Structurec Water used for the study was obtained from Innovative Biotech Limited along Abuja - Kefl. Road while de - chlorinated tap water (Unstructured Water) from the University environment. Two (2) treatments were replicated, each having three (3) groups. Length-weight measurement were taken using electronic weighingbalance,measuringboard and a centimeter rule.Some physio - chemical parameters were determined using titrimetric method while water temperature, DO and BOD were determined using Biocotek water portable DO analyzer model JPB - 607A. Water pH and Electric Conductivity were analyzed using JENWAY portable pH and conductivity meter model number 430. The mean value of temperature for structured water (SW) and Unstructured water (UW) was 27°C while the pH value was 6.96 for SW and 7.51 for UW. DO had mean value of 9.8mg/L in SW and 7.5mg/L in UW. Mean value of conductivity was 62pS in SW and 98.8pS in UW while water hardness recorded a value of 24mg/L in SW and 80mg/L in UW. The mean for BOD was*3.8nig/L in SW and 6.2mg/L in UW. The highest mean weight recorded in SW was 78.1g and mean length of 19.7cm in SW after the ten (10) weeks experimental period which represents the best growth performance. The highest Specific Growth Rate (SGR) in SW was 33% while the lowest value of 29% was recorded in UW. Feed Conversion Efficiency (FCE) had the highest value of 29.4% in SW. The highest Protein Efficiency Ratio (PER) of 1.6% was recorded in SW while the lowest value of 0.9% was observed in UW. Apparent Net Protein Utilization (ANPU) recorded the highest value of 41% in SW whereas the lowest value of 11.16% was observed in UW. Based on the results obtained in the study, Clarias gariepinus fingerlings performed better in SW than U W with the values of 33% SGR, 78.Ig weight and 19.7cm in length. FCE was 29.4%, PER was 1.6% and ANPU was 41%. The use of structured water in aquaculture will give better yield in terms of food output and cash value of the Fish cultured. This is in view of the better growth performance for fish cultured in structured water.
