Early steps in most domestication programs often consider species as a unity, disregarding a part of the biodiversity: the wild intraspecific geographic differentiation. Yet, this differentiation can shape local specificities, which could lead to different domestication predisposition or socioeconomic attractiveness between populations. Therefore, considering this population-specific potential could facilitate domestication and subsequent production of new candidate species. Here, we propose a three-step integrative approach to standardize and facilitate new domestication attempts by taking advantage of wild geographic differentiation. The step 1 consists in classifying the wild biodiversity to identify prospective units (i.e. groups of differentiated allopatric populations). The step 2 allows comparing performances of these units in standardized conditions (i.e. rearing system) through a multi-function and multi-trait assessment. Finally, the step 3 highlights units with higher aquaculture potentials through the calculation of an aquaculture potential score. This approach, here applied to fish culture for human consumption, also aims at being extended to other taxa (e.g. crustaceans, molluscs) and other production goals.
