Ethics approval

: Experiments were carried out in the Aquatic Platform (Plateforme aquatique, <b>Animalerie</b>) of the University Pierre et Marie Curie, Paris, France. The protocols used in this study were designed to minimize discomfort, distress and pain of animals. Protocols followed the guidelines and were approved by the Darwin Ethical committee (Comité d’éthique en expérimentation animale Charles Darwin; case file #Ce5/2010/041) from the French Ministry of Education, Higher Education and Research, which complies with the European Committee Guidelines on the Care and Use of Laboratory Animals. In addition, specific guidelines for standard care of medaka from [CitationRef removed] were followed.The medaka used in the present study are descendants of a 10 generations size-selection experiment developed at CEREEP - Ecotron IleDeFrance service unit, Foljuif, France (see [CitationRef removed] for details in protocol). Those lines were created from a stock of Toyohashi medaka colony. Medaka used in this study were transported as eggs to the University Pierre et Marie Curie, instead of hatched individuals to minimise stress during transportation. No special permit was necessary to transport medaka eggs between the two partner animal facilities.
