In the present study, antibiogram of Escherichia coli isolated from farmed Asian clam, Corbiculafluminea was characterised. Asian clam or locally known as ‘etak’ is processed to became smokedclam and consumed as snack by Kelantanese. However, there are many diarrhoea cases afterconsuming smoked clam. Furthermore, there are also insufficient information about the E.coli levelin Asian clam farm and effective antibiotic in controlling the bacteria in the litereature. Hence, thisstudy was carried out to provide information of antibiogram of E.coli to be reference in the future.Eosin Methylene Blue agar (EMB) was used to isolate E. coli. A total of 100 isolated bacteria weresubjected to antibiotic sensitivity test using disk diffusion method. A total of 18 types of antibioticsnamely novobiocin (30µg/disk), fosfomycin (50 µg/disk), tetracycline (30µg/disk), lincomycin(15µg/disk), flumequine (30µg/disk), sulphamethoxazole (25 µg/disk), amoxycillin (25 µg/disk),chloramphenicol (30 µg/disk), oleandomycin (15 µg/disk), spiramycin (100 µg/disk), ampicillin(10 µg/disk), oxytetracycline (30 µg/disk), doxycycline (30 µg/disk), nalidixic acid (30 µg/disk),florfenicol (30 µg/disk), erythromycin (15 µg/disk), kanamycin (30 µg/disk) and oxolinic acid (2µg/disk). The findings of the present study showed total plate count of E. coli was 6.45 x 103 colonyforming unit (CFU/100g) of sampled Asian clam. Hence, the clam is needed to be under cleansingtreatment before can consider safe for human consumption. Antibiotic results showed 51 % wasrecorded as antibiotic resistance case, 44 % antibiotic sensitive case and 5 % as antibioticintermediary sensitive case. None of the tested antibiotics was successfully inhibited the growth ofthe present bacterial isolates indicating more antibiotics are needed to be screen in the future studyto find out the most effective antibiotic in controlling isolated E. coli.

Aquaculture is one of the fastest growing industries in the world. This industry supplies half of thefisheries products consumed annually, and future global demand can only be supplied by increasingaquaculture production, which, in turn, requires more aquafeed. Alternative ingredients must beincreasingly used to supply significant proportions of protein and energy in aquafeeds, creatingboth challenges and opportunities for researchers and industry. Nowadays, there are too manyresearches on fish disease, growth and health but less in a fish feed especially a replacement ofprotein from plant sources in the fish feed. One of the alternative ways to optimise the growth andhealth condition of the fish is provide them a good protein from plant as a replacement in fish mealwith the natural source protein instead of giving a good rearing condition and caring of the fish.The present article was constructed to highlight a replacement of plant protein sources as analternative of fish meal for fish feed in African catfish, Clarias gariepinus that has been done byresearchers. However, the application of replacement from plant protein sources in fish meal is nowgradually gaining importance in commercial aquaculture practices and opened the door for theresearchers to expend of this application, thus more detailed studies on molecular basis should belooked as to get the quality and enough nutrient fish feed for good production of aquacultureindustry.

Biomass transfer using fertiliser tree species is a more sustainable means for maintaining nutrient balances in maize based production systems. This research investigated the combined effects of incorporation of leafy biomass of fertilizer trees as organic fertilizer and urea as inorganic fertiliser for sustainable food production viz-a-viz maize-based crop in semi-arid, Nigeria. The experiment was laid out as 3 x 4 x 2 factorial in a split-split plot design with three replicates. Data were analysed using Analysis of Variance (ANOVA) at p =.05. Albizia lebbeck amended plots consistently had significantly higher values in 2014, 2015 and combined means (12.8 kg ha-1, 13 kg ha-1, 12.9 kg ha1) of cob length, (345.8 kg ha-1, 311.8 kg ha-1, 328.8 kg ha-1) of grains per cob and grain yield (2097.3 kg ha-1, 1667.7 kg ha-1, 1881.9 kg ha-1) throughout the cropping seasons and combinedeffect respectively compared to Parkia biglobosa. Positive significant correlation was experienced between the growth and yield components. Inclusion of nitrogen fertilizer and fertilizer trees improved the production of these maize varieties compared to control. It is therefore concluded that incorporation of Albizia lebbeck with up to 40 kg N ha-1 rate of nitrogen fertilizer into the soilimproved its quality for better yield of both 2009 EVAT and DMR-ESR-7 maize varieties.
在以玉米为基础的生产系统中，利用肥料树种进行生物量转移是维持养分平衡的一种更可持续的手段。本研究调查了在尼日利亚半干旱地区，肥料树叶生物量作为有机肥料和尿素作为无机肥料对可持续粮食生产(即玉米作物)的综合效应。试验采用3 × 4 × 2的因子设计，分为3个重复。数据分析采用方差分析(ANOVA)， p = 0.05。2014年、2015年，小叶合欢改良小区的穗轴长(12.8 kg ha-1、13 kg ha-1、12.9 kg ha-1)、单穗轴粒数(345.8 kg ha-1、311.8 kg ha-1、328.8 kg ha-1)和籽粒产量(2097.3 kg ha-1、1667.7 kg ha-1、1881.9 kg ha-1)和组合效应均显著高于小叶合欢。生长成分与产量成分呈显著正相关。与对照相比，施用氮肥和肥树提高了这些玉米品种的产量。综上所述，在土壤中施用40 kg N - hm -1氮肥可改善小叶合欢的品质，提高2009年EVAT和DMR-ESR-7玉米品种的产量。

The present work has been done to provide basic data for a better conservation and valorization ofKhaya senegalensis stands in Sudano-Sahelian zone of Cameroon. A 100 m x 50 m transectmethod was undertaken to measure floristic diversity through the use of species richness,Shannon index, Pielou equitability, Simpson index, importance value index and importance valuefamily. The vegetation structure is determined by density, basal area and biovolume. Theinventory included trees with a dbh ?10 cm on an area of 1 ha per plot. A total of 6743individuals distributed in 24 families, 33 genera and 54 species were inventoried in all Khayasenegalensis stands studied. Statistical analysis showed significant differences, Shannon index,Simpson index, Pielou equitability, density, basal area, biovolume, species richness, heights class,diameters class, circumferences class but does not certify a significant difference of importancevalue index among in the villages. The undergrowth of Khaya senegalensis stands is more diverseat Bamé with a Shannon diversity index (ISH=5.87 ± 0.12 bit). The greatest of Pielou equitabilityis observed at Bamé (EQ=0.80 ± 0.01). The largest of Simpson index is recorded at Bamé(D=0.098 ± 0.001). Khaya senegalensis Stands are denser at Bamé (194 ± 3.12 individuals/ha).The basal area and biovolume of Khaya senegalensis stands are very high at Bamé (BA=25.87 ±0.06 m2/ha and Biovolume =15.32 ± 0.012 m3/ha). The species importance value is maximal in allthe studied villages (SIV=300 ± 71.45). The importance value index of species revealed a cleardominance in the undergrowth of Khaya senegalensis stands are Combretum adenogonium;Acacia senegal; Terminalia laxiflora; Guiera senegalensis; Acacia nilotica; Entada Africana.The vertical structure has three aspects, like the L (Dbh), asymmetric (height) and dissymmetrical(circumference) structures attesting to a strong regeneration of the understory ligneous woods ofKhaya senegalensis stands studied.

The present study investigated the floristic structure and ecological role of Rourea afzelii stands insavannah, forest galleries and swampy areas to Cameroon. An 80 m x 50 m transect method wasundertaken to measure floristic diversity using Shannon index, Pielou equitability, Simpson’s indexand the importance value index. The structure of Rourea afzelii stands is determined by density,basal area and biovolume. The results of this study show that Rourea afzelii stands are morediversified in savannah with a Shannon diversity index (ISH =4 ± 0.03bit). The highest log stabilityof Rourea afzelii stands is observed in the savannah (EQ=0.75 ± 0.008). The Simpson index of theRourea afzelii stands is larger in the forest gallery (D=0.088 ± 0.0022). Rourea afzelii Stands aredenser in savannah (113 ± 2.54 individuals/ha). The basal area and biovolume of Rourea afzeliistands are very high in swamp area (St=15.75 ± 0.02 m2/ha, Biov=9.08 ± 0.12 m3/ha). The diametricstructure has an asymmetrical “L” shaped appearance, indicating a strong regeneration of Roureaafzelii Stands in the three sites studied. Rourea afzelii Stands in forest galleries sequestered morecarbon (26.41 ± 0.0015 ton C/ha) than those in savannahs and swampy areas. This valuecorresponds to sequestration of carbon dioxide of 96.92 ± 0.82 ton CO2/ha. Economically, thiscorresponds to the CDM carbon price (290.77± 3.332 Euros/ha), a Voluntary Market Carbon Priceof 455.54 ± 1.908 Euros/ha, a REDD + carbon price of 9692 ± 8.152 Euros/ha. In conclusion, theresults of this study can be used in the context of protection and conservation as well as thedomestication of such a species.
本文研究了喀麦隆热带稀树草原、森林廊道和沼泽地区乌利亚林分的区系结构和生态作用。采用80 m × 50 m样带法，利用Shannon指数、Pielou公平度、Simpson指数和重要值指数测定植物区系多样性。林分结构由密度、基面积和生物量决定。研究结果表明，在热带稀树草原上，红豆林分的多样性较高，其Shannon多样性指数(ISH =4±0.03bit)。大草原林分的对数稳定性最高(EQ=0.75±0.008)。林间廊道林分的Simpson指数较大(D=0.088±0.0022)。热带稀树草原红木林分密度较高(113±2.54株/公顷)。沼泽区Rourea afzelies岛的基底面积和生物体积非常大(St=15.75±0.02 m2/ha, Biov=9.08±0.12 m3/ha)。直径结构呈不对称的“L”形外观，表明在三个研究地点，Roureaafzelii林分具有很强的再生能力。林道林分固碳量(26.41±0.0015 t C/ha)高于稀树草原和沼泽林分。这一数值相当于二氧化碳固存量为96.92±0.82吨/公顷。经济上，这相当于CDM碳价(290.77±3.332欧元/公顷)，自愿市场碳价(455.54±1.908欧元/公顷)，REDD +碳价(9692±8.152欧元/公顷)。综上所述，本研究结果可用于该物种的保护和驯化。

Utilization of soy waste as a ruminant feed is low due to storage problems and transportation costs.An experiment was carried out with fifteen goats to assess the feeding value of Napier grass(Pennisetum purpureum) ensiled with or without soy waste. Grass ensiled without soy waste wastermed as NM silage, while grass ensiled 30% soy waste (w/w) was termed as NMS silage. In bothsilages, 1.0% molasses (w/w) were incorporated to enhance the fermentation process. After 2months of ensiling, three diets were formulated and assigned to one of three groups: (i) Napier grassad libitum plus 1% pellet of body weight (BW) on a dry matter (DM) basis (T1), (ii) NM silage adlibitum plus 1% soy waste of BW on a DM basis (T2), and (iii) NMS silage ad libitum (T3). TheNMS silage showed a lower pH (4.04 vs. 4.64) than NM silage. The NMS silage exhibited higherproportions of DM, organic matter (OM), and crude protein (CP) compared to NM silage. Animalsreceived T1 diet showed higher (p<0.05) DM, OM and neutral detergent fibre intake compared tothe animals received T2 and T3 diets. However, animals received T2 diet showed higher CP intakethan the animals received T1 and T3 diets. Similarly, animals received T2 diet showed higher(p<0.05) BW gain (49.4 vs. 16.5 g/d) than the goats fed T3 diet. In conclusion, the T3 diet mayhave limited goat performance, which needs further study to improve the quality of silage.
由于储存问题和运输成本，大豆废料作为反刍动物饲料的利用率很低。以15只山羊为试验对象，研究了添加或不添加豆渣青贮纳皮草(Pennisetum purpureum)的饲喂价值。青贮不含豆渣的青贮草为NM青贮，青贮30%豆渣(w/w)的青贮草为NMS青贮。在两种青贮中均添加1.0%糖蜜(w/w)以促进发酵过程。青贮2个月后，配制3种饲粮，分为3组:(i)纳皮草料+ 1%干物质(DM)基础上的体重(BW)颗粒(T1)， (ii) NM青贮料+ 1%干物质基础上的体重(BW)颗粒(T2)， (iii) NMS青贮料自由(T3)。TheNMS青贮pH值(4.04比4.64)低于NM青贮。NMS青贮的DM、有机质(OM)和粗蛋白质(CP)含量均高于NMS青贮。与T2和T3组相比，T1组动物的DM、OM和中性洗涤纤维摄取量显著增加(p<0.05)。然而，T2组动物的粗蛋白质摄入量高于T1和T3组动物。T2组的体重增重(49.4 g/d vs 16.5 g/d)高于T3组(p<0.05)。综上所述，T3饲粮可能限制了山羊的生产性能，需要进一步研究以提高青贮品质。

Soil is a complex matrix and a major reservoir of contamination. It can bind many potential toxicelements such as heavy metals, and they can exist in various forms. The main objective was tocharacterize the soil sample in relation to heavy metal concentrations in the Tanah Merah wastedumping site. Soil samples were taken from three different locations around the waste dumping siteand determined by Atomic Absorption Spectrophotometry (AAS) for Cu, Fe and Zn determination.High concentrations of Fe (9.18 mg/L) as compared to Cu (0.53 mg/L), and Zn (0.49 mg/L) werefound in the soil samples but were lower than previous studies. However, early precautionaryactions need to be implemented since a higher volume of waste disposal in the future might causechanges in heavy metals intensity at the waste dumping site.

Water quality change is caused by indirectly or directly sources such as human activities,uncontrolled sewage, or heavy metals and sediments. This study was conducted at two famousecotourism places in Jeli, Kelantan which are Lata Janggut and the new ecotourism place, LataKeding. The main objective of this study is to compare water quality index and heavy metals at thecascades. Twelve samples were collected from two points which are flowing water and stagnantwater in each cascade. Mann Whitney test was used to determine whether there are significantdifferences in concentration of each physical and chemical parameters between Lata Keding andLata Janggut. Spearman correlation was also used to determine the relationships between physicaland chemical parameters. This study found that Water Quality Index (WQI) in Lata Janggut is 69.07(Class III) and Lata Keding is 71.75 (Class III) which means that the water quality was slightlypolluted for both cascades. Therefore, Lata Janggut and Lata Keding require extensive treatment ifit will be used for water supply but still under control and safe to had body contact with the water.However, further monitoring are needed to avoid any environmental issues arise.
