Towards the development of clonal lines in the European sea bass (Dicentrarchus labrax L.): application of uniparental reproduction techniques with an insight into sea bass eggs ArchiMer
Colleter, Julie.
Clonal lines are a powerful scientific tool for improved genetic characterization of organisms used in research. Inbred fish lines can be produced in only two generations using uniparental reproduction techniques. Androgenesis, achieved with variable success in several freshwater species, has been attempted in the European sea bass (Dicentrarchus labrax L), a marine fish of commercial and scientific interest. The low yields of progenies inheriting only the paternal genome after UV-irradiation of eggs led to considerations on the occurrence of UV screening compounds in pelagic eggs. Mycosporine-like amino acids and gadusol were found in many marine and freshwater organisms, but their occurrence in fish eggs was not clearly related to a behavioral pattern...
