    (Department of Zoology, Faculty Of Natural And Applied Sciences, Nasarawa State University, Keffi, 2019-05-16) Ameh, S.M.,; Makpo, James Kpuk; Sotolu, A.O.,; Banyigyi, A.H.; Cheka, B.C.
    This study determined the growth performance and feed utilization of catfish (Clarias gariepinus) fingerlings reared in structured and unstructured water, (de-clorinated tap water]. Structured Water used for the study was obtained from Innovative Biotech Limited along Abuja - Keffi 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 weighing balance, measuring board 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 98.8gS in UW while water hardness recorded a value of 24mg/L in SW and 80mg/L in UW. The mean for BOD was 3.8mg/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 . UW with the values of 33% SGR, 78.lg 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. '

    STUDIES ON SOME PHYSICO - CHEMICAL PARAMETERS AND BACTERIAL GROWTH IN THE GUT OF CATFISH (Clarias gariepinus) FINGERLINGS REARED IN STRUCTURED AND UNSTRUCTURED WATER
    (Department of Zoology, Faculty Of Natural And Applied Sciences, Nasarawa State University, Keffi, 2019-10-17) Ameh, S.M.,; Makpo, James Kpuk; Banyigyi, A.H.
    Water is ubiquitous in nature, and it may be from this property that it is frequently taken for granted. For the last few decades, researchers have been differentiating "bulk water" from other forms of water'and there is now a name for this other water presently referred to as Exclusive Zone or EZ water. It is also called structured water, energy water, reactivated water, activated water, etc. The studies on some physico — chemical parameters and bacterial growth in the gut of Catfish (Clarias gariepinus) Fingerlings reared in structured and unstructured water was carried out in the Zoology Laboratory of Nasarawa State University Keffi. Water temperature was analyzed using a dry mercury thermometer. Dissolved Oxygen and Biological Oxygen Demand (BOD) were determined using Biocotek water portable DO analyzer, model number JPB - 607A. Water pH and Electric Conductivity were analyzed using JENWAY portable pH and conductivity meter, model number 430 while the titrimetric method was used in analyzing water hardness. The mean value of water temperature for Structured Water (SW) and Unstructured water (UW) was 27°C, pH value was 6.96 for SW and 7.51 for UW. Dissolved Oxygen had a mean value of 9.8mg/L in SW and 7.5mg/L in UW. Mean value of electrical conductivity was 62pS in SW and 9S.8pS in UW while water hardness recorded a value of 24mg/L in SW and 80mg/L in UW. The mean value for BOD was 3.8mg/L in SW and 6.2mg/L in UW. Bacterial growth was investigated using MacConkey Agar (MAC) and Eosin Methylene Blue Agar (EMB)._ The initial analyses for MAC and EMB recorded no growth of bacteria, which meant their absence. In the final analysis of MAC, Catfish (Clarias gariepinus) reared in UW showed bacterial growth with pink-red colour while poor growth of bacteria was recorded in fish reared in SW. In EMB, the final analysis of the fish sample reared in SW showed Mucoid pink and Colorless colonies, an indication of organism fermenting neither Lactose nor sucrose while in UW, colonies appeared purple — black showing bacterial growth in the gut of the fish. This result indicates the repulsive nature of structured water (SW) to harmful germs in the living cells of an organism which helps to maintain a healthy environment within the cell.
