Sexually segregated housing results in improved early larval survival in zebrafish. / Mark S. Kurtzman in LabAnimal-Europe, 7/10 (Juillet 2010)

Public ISBD [article]  inLabAnimal-Europe > 7/10 (Juillet 2010) . - p. 23-33 Titre : Sexually segregated housing results in improved early larval survival in zebrafish. Type de document : texte imprimé Auteurs : Mark S. Kurtzman Année de publication : 2010 Article en page(s) : p. 23-33 Langues : Anglais (eng) Résumé : Large-scale aquaculture facilities require highly optimized husbandry protocols that maximize fecundity and embryo health while minimizing cost and effort. Although zebrafish are being increasingly used for preclinical drug screens, functional genomic research and toxicological and behavioral studies, many of the basic husbandry procedures that are used for these fish have not been thoroughly tested. In this study, the authors compared the breeding success of zebrafish housed in sex-separated and those housed in mixed-gender arrangements. They observed a significant increase in fecundity (egg production) between the first and the third breeding and found that egg survivorship tended to increase during successive pairings. The authors also found that zebrafish had higher fecundity, egg viability and seemed to have a higher breeding success rate when males and females were housed separately than when they were housed together.
