Conversion factors and statistical analyses Growth, CO2 production and feed assimilation were expressed as specific rates based on the mass fraction of carbon in the larvae, in the substrates and in CO2. Thereby, the magnitudes of the rates could be compared in the same unit (Laganaro et al., 2021). Carbon was assumed to make up 49% of the organic fraction of the larvae and substrates, which is the carbon content in biomass of average elementary composition (Roels, 1980).
