B. Iriyadi, S. Nompo, S. Hasan

Abstract Background: that liquid organic fertilizer could be a good alternative in replacing inorganic fertilizers. Meanwhile, the water hyacinth is a plant that has the potential to be used as the basic material in liquid organic fertilizer production. It is, therefore, necessary to study scientifically the effect of liquid organic fertilizer produced from water hyacinth to the production and the quality of Brachiaria brizantha. Objective: the object of this study are hyacinth and gala leaves as organic fertilizer as well as Brachiaria brizantha. Results: The results of the analysis of variance indicated that the effect of liquid organic fertilizer at a dosage of 0,10,20,30,40 ml/poly-bag on the production and the quality of Brachiaria brizantha was significant on the number of tillers and leaf chlorophyll. However, there was no significant effect on the plant height, leaf numbers, leaf area, fresh matter production and crude protein content. Conclusion: Based on the research, it can be concluded that the supplementation of liquid organic fertilizer indicated good response in terms of production and quality of Brachiaria brizantha. The supplementation of liquid organic fertilizer at the dosage of T4 is the best treatment. Although the results indicate no significant difference, the results consistently showed an increasing tendency.

Abstract Ekiti East Local Government Area Southwestern Nigeria suffered continual shortage of potable water arisen from lack of government pipe borne water and incessant boreholes failures. Therefore, this research was carried out with the objectives of estimating aquifer parameters (transmissivity, specific capacity and borehole yield) and classifying the study area into different groundwater potential zones. Siting of 35 boreholes locations was carried out using vertical electrical sounding geophysical technique. Boreholes were drilled in the 35 locations and pumping test was carried out in each of the borehole. Data from the thirty-five (35) boreholes were interpreted using Jacob straight line graphical simplification method which entailed plotting of time versus drawdown on a semi-log paper. A best straight line fit for the plot was subsequently drawn and extended to cut across the drawdown axis. Two points on a log-cycle apart in time were chosen and change in drawdown over that time interval was determined (ΔS). Yield (Q) was determined from the pumping volume per time i.e. volume /time. Transmissivity (T), specific capacity (Cs) were estimated using T= 2.3Q/4πΔS and Cs = Q/ΔS respectively. Parameters obtained from the interpretation of the pumping test were employed to generate the yield, transmissivity, specific capacity and groundwater potential maps respectively using Surfer 12 software. Subsequently, the transmissivity values were subjected to quantitative evaluation employing statistical method and transmissivity analysis. Results of the pumping test revealed that the boreholes yield ranged from 0.38 – 1.43 (av. 0.98) L/s, transmissivity from 0.007 – 0.095 (av. 0.034) m2/min and specific capacity from 0.038 – 0.52 (av. 0.183) m3/min/m. Statistical/Transmissivity analysis revealed that the standard deviation of the estimated transmissivity index , signified extreme large variations in transmissivity and heterogeneous environment with varied aquiferous conditions over a short lateral distance. Furthermore, the result indicated that 74% of the study area (mostly northern part) has groundwater occurrence that was good for local water supply while the remaining 26% in the southern part especially at Isinbode-Ekiti has groundwater potential that could serve for private consumption only. The groundwater potential map zoned the area into good, fair and poor groundwater potential zones. The good groundwater potential zone is in the north central and north-eastern part of the study area. Groundwater in the study area is suitable for local water supply except at Isinbode-Ekiti where it could only serve for private consumption. This study, apart from providing a frame work for groundwater resources development in the area, it serves a guide to other researchers and intending boreholes drillers.

Babalola T.O., Salami M., Olasunkanmi J.B. and Jimoh J.O.

Abstract The purpose of this study was to evaluate the effects of replacing soybean meal with fermented and autoclaved castor seed meal on growth performance, carcass quality and haematological parameters of Clarias gariepinus fingerlings. 150 Clarias gariepinus fingerlings with initial body weight 5.61 ± 0.03 were used in this study. The fish were equally distributed over 15 aquaria (120 l each, triplicate per treatment). Fermented and autoclaved castor seed meal (FACSM) was prepared by soaking de-oiled seed in water to allow natural fermentation for five days, dried and autoclaved at 15psi pressure and temperature of 1200C for 30 minutes. The resulting cake was incorporated into five isonitrogenous and isocaloric diets. The diets consisted of five levels of soybean meal substituted with FACSM. The control diet (FACSM0) contain no FACSM, in the other four diets soybean meal was partly replaced with FACSM resulting in the FACSM50, FACSM100, FACSM150 and FACSM200 diets. At the end of the study, no significant differences were observed in the growth performance of fish fed the control diet and fish fed diets containing FACSM up to 100 gkg-1 (diet FACSM100). The carcass quality of the fish indicated that fish fed diet FACSM50 was as good as the fish fed the control diet. The fish health status based on the haematological parameters measured, was not affected by the incorporation of FACSM in the diet up to 50 gkg-1 (FACSM50). The use of fermentation with 30 minutes autoclaving of castor seed meal led to improvement of growth, carcass quality and haematology of C. gariepinus fingerlings. Therefore, the inclusion of FACSM in the diets of C. gariepinus at 50 gkg-1 (diet FACSM50) is recommended because it improved growth performance, carcass quality and fish health status.

Hatice Banu Keskinkaya, Cengiz Akköz , Numan Emre Gümüş, Serdar Karakurt

Abstract Background: Living organisms in the aquatic environment environmental waste/chemicals they are exposed to various molecules. Too much toxic chemical is a very important threat to the health of organisms living in the sea and to the consumer of these organisms, Therefore, it is very important to identify the relationship between the pollutant level (exposure) and its biological effects before any harmful effects are generated at the higher organization level. Objective: This study was carried out to clarify the possible effects of pollution in Beyşehir and Çavuşçu Lakes on the activities of CYP450 enzymes that perform detoxification and metabolic activation of environmental toxins, environmental agents containing mutagen and carcinogens. We aimed at this study to investigate the effect of toxic and carcinogenic organic pollutions of lake carp (Cyprinus Carpio L.,1758) in Beysehır and Cavuscu Lakes. In this way, CYP450 enzymes have been used as a biological indicator to determine the presence of organic pollutants. Hepatic cytochrome CYP2E1 and CYP3A4 enzyme activities of induction with organic pollutants assets in determining early warning signal task, making it the most sensitive biological indicators were be used in fish. In 2014 and 2015 samples of carp were brought from the designated localities and their CYP2E1 and CYP3A4 activities were measured with ELISA by spectrophotometric method. Results: CYP2E1 activity was found as 101,5±9.661, 98,17±1.124 (n=6) pmol/min/mg in Cavuscu and Beysehır lake carp samples, respectively. Both ın the lake, the effect of CYP2E1 activity, there was no significant difference however, CYP3A4 activity was determined as p=0.0073, and the difference between the two lakes was statistically significant. (p<0.05) Fe was found to be higher in liver samples (255,82 mg/kg) in Beyşehir lake than in the Çavuşçu Lake (61,91 mg/kg). Cd and Co levels are below the detection limit in the examples in Çavuşçu Lake and also Cr levels were determined as 0.14 mg/kg and no significant difference was observed between the levels in the samples in Beyşehir Lake. Mn levels were measured at similar rates in the samples in Beyşehir and Çavuşçu Lake (1.15 mg/kg, 1.17 mg/kg, respectively) Conclusion: According to these results, it is thought that pollutants can pass to humans through the consumption of fish in the aquatic environment or the food chain. Exposure to organic pollutants including environmental toxicants and exposure to these chemicals is thought to increase the likelihood of clinical toxicity and is known to be a carcinogen. Besides, it is considered that the concentration of pollutants, aquatic organisms, and human beings are the other important issues to be investigated.
