| Abstract | The effects of chronic dietary selenomethionine (SeMet) exposure on the visual system of adult zebrafish and their progeny were investigated. Adult zebrafish were exposed to measured concentrations of 1.1 (control) and 10.3 µg Se/g dry mass as SeMet for 57 days, then encouraged to breed. Progeny were reared to swim-up and differences in mortality, eye size and visual behaviour were determined. Adult vision was also investigated using behavioural assays. Adults fed the SeMet-spiked diet exhibited significantly fewer positive reactions in the escape response assay when compared to controls. Larvae from adults fed elevated SeMet had smaller eyes and a lower proportion of positive responses in phototaxis, oculomotor and optokinetic response assays compared to controls. These results demonstrate that environmentally relevant elevated dietary SeMet exposure can affect the visual system of both exposed adult zebrafish and their progeny, which could affect fitness and survivability. |

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.
