Despite the ubiquitous threat posed by iron bacteria contamination in groundwater sources, limited research has focused on physical treatments to address this issue. We sought to investigate the effectiveness of ultraviolet (UV) irradiation on inactivating iron bacteria and slime forming bacteria in a fish hatchery supply water known to have issues with bacterial biofilms. Biological activity reaction tests (BART) were used to analyze the presence or absence of iron related and slime forming bacteria in raw well water at UV dosages of 0 mJ/cm2, 15 mJ/cm2, 30 mJ/cm2, 45 mJ/cm2 and 60 mJ/cm2. Results suggest that UV treatment decreases iron bacteria survival, with the highest percent of non-reactive BARTTM test vials resulting from 45 mJ/cm2 and 60 mJ/cm2 UV exposure; however, data regarding UV inactivation of slime forming bacteria were inconclusive. These initial ‘proof of concept’ findings can be used to design pilot UV water treatment systems for fish hatcheries known to have iron bacteria problems. Pilot treatment system testing can then provide the necessary results to ensure that UV treatment is effective against site-specific iron bacteria populations before full-scale treatment systems are implemented.","PeriodicalId":15243,"journal":{"name":"Journal of Aquaculture Research and Development","volume":"22 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75425457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six of seven presumptive Pseudomonas sp. were successfully identified by API 20NE method to level species; they were identified as 2 P. fluorescens, one P. putida, one Pseudomonas sp and 3 Burkholderia cepacia while genotypically with 16S rRNA gene sequencing that proved successful for all the four pseudomonas isolates (three as P. fluorescens and one P. putida). The results of phylogenetic analysis placed the isolates in the genus Pseudomonas based on 99% homology. Challenged test revealed that, P. fluorescens and P. putida are to be classified as pathogenic for O. niloticus and they also exhibited clinical signs and mortality rates up to 70% and showed histopathological changes of both liver and kidney which lead to death. The antibiogram study showed that no significant differences between P. fluorescens and P. putida which had intrinsically high sensitivity to nucleic acid synthesis inhibitors such as ciprofloxacin, norfloxacin, gentamycin, gatifloxacin, lomefloxacin and kanamycin. This study concluded that good overall agreement between phenotypic and genotypic identification procedures was found for the isolates with some minor differences in biochemical and physiological characteristics were observed between P. fluorescens strains, while the genotypic differences were significant observed between P. fluorescens and P. putida isolated from various fishes.","PeriodicalId":15243,"journal":{"name":"Journal of Aquaculture Research and Development","volume":"131 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2017-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86351109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirteen quantitative variables were used for a principal component analysis (PCA). Four principal components had eigenvalues greater than 1, collectively expressing 77.0% of the total variance with the first two components, (50.8% of total variance) reflecting the volume of fry production and available facilities. \u0000Multiple correspondence analysis (MCA) was used to include qualitative variables related to hatchery management and educational level of the owners in the analysis. A two-step cluster analysis using the results of PCA and MCA identified two different groups of hatcheries.
