Domestication et croissance chez les poissons

Abstract : Studying two successive phases of fish production cycle, larval rearing and growing phase, fish growth patterns were analysed to perform a functional typology. For all developmental stages, high growth heterogeneities (intra and inter-specific) were observed. They were explained by the effects of intrinsic and external factors (biotic and abiotic). For the growing phase, this high phenotypic variability does not allow to sort out species according to their growing pattern. This effect is partly due to strong interactions of growth with other physiological functions (e.g. reproduction). Growing pattern does not seem to be discriminative. For larval rearing (larval, post-larval and juvenile stages), growth heterogeneity and cannibalism could be related to the living strategies of fish species.
