Respiring Pseudomonas spp. in milk were quantified within 6 h by fluorescence in situ hybridization (FISH) with vital staining. FISH with an oligonucleotide probe based on 16S rRNA sequences was used for the specific detection of Pseudomonas spp. at the single cell level. 5-cyano-2,3-ditolyl tetrazolium chloride (CTC) was used to estimate bacterial respiratory activity. The numbers of respiring...

Aquaculture has been an important economic sector in Vietnam due to its rapid growth and considerable contribution to national fisheries production. With data collected from a field survey interviewing 120 fish farmers in southern Vietnam, this study uses a cumulative logistic model to extend the satisfaction approach to an analysis of the farmers’ satisfaction with their fish farming. Regressi...

From the inception of the supervised industrial work experience scheme (SIWES) in Nigerian institutions of higher learning quite many students have done it at African Regional Aquaculture Centre (ARAC). In the year 2010 alone 340 students were in ARAC for of these students lacked functional understanding of the underlying principles and practices of water quality management at the planning and ...

the inhibition of pathogens growth as well as the shelf-life extension of seafood as a perishable product using safe methods is one of the most important issues that have been attracted fisheries and food science researcher’s attention. the purpose of this study was to evaluate the inhibitory effect of bunium persicum essential oil (eo) on inoculated listeria monocytogenes growth in simulated b...

We evaluated the survival of Streptococcus agalactiae from naturally infected wild mullet (Liza klunzingeri) and experimentally infected Nile tilapia (Oreochromis niloticus) frozen at 20 and 70 jC, respectively, for an extended period of time. The brain, eye, head kidney, and intestine of individually frozen wild mullet (N = 22), culture positive for S. agalactiae from fresh tissues following a...

Cross-cultural comparisons of categorization often confound cultural factors with expertise. This paper reports four experiments on the conceptual behavior of Native American and majority-culture fish experts. The two groups live in the same general area and engage in essentially the same set of fishing-related behaviors. Nonetheless, cultural differences were consistently observed. Majority-cu...

Sangam literature conveys to us the high character, way of life, and experience Tamils. The five divisions ancient Tamil society (ainththinai) were characterised by numerous cultures. In later stage, based on term attribute, word "culture" was constructed. Culture refers biological structure human society. One main elements culture is food. Tamils excelled in cooking food with taste, selecting ...

With fluorescently labeled PNA (peptide nucleic acid) probes targeting 16S rRNA, we established a 3-h fluorescence in situ hybridization (FISH) procedure for specific visualization of members of the Mycobacterium tuberculosis complex, M. leprae, M. avium, and M. kansasii. Probe specificity was tested against a panel of 25 Mycobacterium spp. and 10 gram-positive organisms. After validation, prob...

Background: Test of pahogenecity of fish pathogens usually done by injection or ingestion of the bacterial samples on the fish. Objective of the current research was to introduce a new method of testing pathogenecity of fish pathogens through an artificial infection system. The targeted method was to observe the pathogenecity in aquarium condition by direct infection of the system water with ba...

A highly pathogenic isolate of Aeromonas hydrophila, isolate No1, was identified through evaluation of the Crude extra-cellular product and estimation of LD50. Three types of formalized whole culture Aeromonas hydrophila vaccine (FWC) were prepared, FWC vaccine alone, FWC vaccine mixed with Freund's complete adjuvant (FCA), and FWC vaccine mixed with Freund's incomplete adjuvant (FIA), tested f...
