| Abstract | Relationships between feeding status and the biliary concentrations of biliverdin and metabolites of polycyclic aromatic hydrocarbons (PAH) have been investigated in plaice (Pleuronectes platessa) from the Firth of Clyde, Scotland. Plaice were caught at three times of the day, and kept, without feeding, in tanks for up to 24h. The mean concentrations of biliary PAH metabolites 2-OH naphthalene, 1-OH pyrene and 3-OH benzo-[a]-pyrene (3-OH B[a]P) were found to increase slightly over a 24h non-feeding period (only significant for 3-OH benzo-[a]-pyrene). This effect was not observed for mean biliary concentrations of 1-OH phenanthrene. During this period of starvation, bile volume, total amounts of all PAH metabolites in the gall bladder, and biliary biliverdin concentrations all significantly increased. No significant relationships (P>0.05) were found between indicators of feeding status and individual PAH metabolite concentrations, confusing the rationale for normalisation of data to account for differences in feeding status between fish. Normalisation of PAH metabolite concentrations to biliverdin concentrations did not consistently reduce the variance of the metabolite data for fish sampled after the same starvation period. However, the variation between mean metabolite concentrations of fish suffering different starvation periods was reduced by biliverdin normalisation for most of the metabolites measured. It is therefore recommended that biliary PAH metabolite data should be presented as raw concentrations, except in cases where there may be significant differences in feeding status between groups of fish. In such instances biliverdin normalised data should also be reported and observational guides such as bile volume and stomach contents may aid in the interpretation of data. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
