Correlations of age and growth rate with microbiota composition in Atlantic cod (Gadus morhua) larvae

Abstract Little information is available on the link between host development (growth rate and ontogeny) and the composition of the microbiota in fish larvae. This study was carried out to examine potential correlations of microbiota composition with age and growth rate of Atlantic cod larvae. Small...
