In the present investigation extracts of Sesbania grandiflora and Carica papaya were screened for their antimycobial activities against the fungi isolated from fish samples. The isolated fungi include AIlams, A.niger, Cladosporium and Mucor. Recently, management techniques over the control of molds using plant-based products are widely recommended. Sesbania grandiflola extract was found to be most effective against, A.flavus and Cladosporium. the inhibition zone being 37mm at 25% concentration and Carica papaya produced 36 mm inhibition againgt Mucor. So present study proves the possibility of using these plant extracts as antifungal agents.Item Bioaccumulation of Heavy Metals in Commercially Important Edible Marine Fishes(2014) Krishnaveni, NHe avy metal d i sp o s ed th rough anthropogenic activities finds their way into the oceans and seas through the rivers or through direct fallout from factory effluents. These heavy metals re-suspend back into water column along with the sediments and are known to affect the marine animals. The objective of this study was to determine chromium, nickel, c a dmium and zinc concentration levels in edible marine fishes collected from the coastal area of Tuticorin, India. Measurement of heavy metal content of the selected fish was carried out by using atomic absorption spectrophotometer. The metal content, expressed in pg g"' wet weight for chromium, nickel, cadmium and zinc varied from 4.706-9.020, 3.307-16.760, 9.053- 9.480 and 9.878-12.126 respectively. The values were comparable and in the range of the literature values. The results of this study indicate that the selected fish have concentrations well below the standards of FAO/WHO levels of these toxic metals except chromium.Item Credit Card Fraud Detection Using Machine Learning and Deep Learning Techniques(2021-05) Kirubavathi, M; Krishnaveni, NItem Culture and Use of An Eukaryotic Microorganism (Paramecium) For Depollution of An Effluent(1995-05) Revathi, N; Krishnaveni, NItem Dietary Medicinal Herbs Improve Growth and Biochemical Composition of Common Carp, Cyprinus Carpio Fingerlings(2010) Krishnaveni, NCyprinus carpio fmgerlings were fed with various levels of the commercial herbal growth promoter ('Liv.52'). After 60 days of culture, a very positive result was found in 'Liv.52' fed fmgerlings. The administration o f Liv.52' in all the levels produced significantly (P<0.05) higher weight gain and muscle proximate composition (moisture, protein, carbohydrate, fat, ash and calorific contents). The utilization of feed increased significantly (P<0.05) in the supplemented diet fed fish from that of control. Among the different percentages, 20% 'Liv.52' incorporation performed better in the overall status.Item Dietary Probiotic (Bifilac) Supplementation in the Reproductive Performance of White Molly, Poecilia sphenops(2014-03) Chithra, P; Krishnaveni, NItem Effect of Herbal Biomedicine on The Growth of Fresh Water Fish Oreochromis Mossambicus(2011-04) Kalyani. M; Krishnaveni, NItem Effect of prawn waste as feed ingredient on the growth, nutritional status and feed utilization on the fresh water fish, Catla catla (Hamilton, 1822)(2019-04) Keerthika, R; Krishnaveni, NItem Effect of Probiotics on Reproductive Performance in Female Livebearing Ornamental Fish Poecilia Sphenops(2013) Krishnaveni, NA study was carried out to determine the effect of varying dietary probiotic levels on the reproductive performance of a fresh water ornamental species, the black molly (Poecilia spenops). The commercial probiotic, Vibact were mixed thoroughly with the artificial feeds at concentrations of 0.2% (T1 ), 0.4% (T2), 0.6% (T3) and 0.8% (T4) and fed to healthy fish for a period of 60 days. The obtained results showed that supplementation of probiotic feed increased significantly (P<0.05) the fecundity, fry production, fry survival and gonado somatic index (GSI). Fishes fed with 0.4% (T2) of probiotic supplementation showed significantly (p<0.05) better results when compared to all the test diets and control. Based on these data, it is concluded that female black molly brood stocks benefit from inclusion of Vibact in diet during their reproductive stages. Further, study is needed to know the mechanism of action for probiotics such as Vibact and their applications.Item Effect of Supplementation of Selected Plant Leaves as Growth Promoters of Tilapia Fish {Oreochromis Mossambicus)(2014) Krishnaveni, NAn investigation was carried out to evaluate the effect of selected plants (Sesbania grandiflora, Moringa oleifera, Coleus aromaticus, Ocimum basilicum and Solanum verbascifolium) supplemented feed on the growth parameters such as length gain, weight gain and specific growth rate of Oreochromis mossambicus. Five experimental feeds were prepared by adding 5 grams of plant powder to the basal diet and one control feed without plant powder. The fishes were supplemented with these feeds for 45 days and the results were obtained for every 15 days once. The data were anaylzed usinh one way analysis of variance (ANOVA) and the means were separated using least significant differences. The fishes fed with Moringa oliefera supplemented feed showed maximum increase in weight (0.96%, 1.33%, 1.78%) and specific growth rate. The maximum increase in length was observed in the fishes that were fed Ocimum basilicum supplemented feed (1.2%, 1.6%, 2.0%). This study indicated that inclusion of plant ingredients in fish feed resulted in superior growth performance and the formulation of plant based diet for fish will provide new opportunities.Item Effects of Garlic and Onion Incorporated Feed on The Growth, Nutritional Status And Enzymes on The Fresh Water Fish Tilapia, Oreochromis Mossambicus(2013-05) Vigneshpriya, D; Krishnaveni, NItem Efficacy and Characterization of Orange Peel As Bioadsorbent In Sewage Treatment For The Growth Of Edible Fish, Labeo Rohita [Ham.](2015-03) Mary Steffy, A; Krishnaveni, NItem Efficacy of curry leaf formulated feed on the growth, nutritional status and feed utilization efficiencies of Indian major carp, Catla catla (Hamilton, 1822)Efficacy of curry leaf formulated feed on the growth, nutritional status and feed utilization efficiencies of Indian major carp, Catla catla (Hamilton, 1822)(2019-04) Rasathi, B; Krishnaveni, NItem Efficacy of Formulated Feeds on Growth, Nutritional Indices and Feed Utilization Efficiencies of Indian Major Carp, Catla Catla (Hamilton, 1822)(2009-09-30) Chitra, G; Krishnaveni, NItem Efficacy of fruit waste formulated feed on growth and reproduction of the ornamental fish, Poecilia sphenops(2014-03) Karthika, K; Krishnaveni, NItem Enhanced Multi-Feature based Machine Learning Techniques for Identification of Online Spam Reviews(2021-07) Krishnaveni, N; Radha, V
