Unlocking the wild potential : integration of geographic differentiation in domestication processes to facilitate fish aquaculture diversification
Nowadays, there is a will to develop a more sustainable aquaculture. One of the ways supported to promote the sustainability of the aquaculture sector relies on the production diversification, notably through the domestication and production of new species. However, domestication is a long and diffi...

Nowadays, there is a will to develop a more sustainable aquaculture. One of the ways supported to promote the sustainability of the aquaculture sector relies on the production diversification, notably through the domestication and production of new species. However, domestication is a long and difficult process which can fail due to technical challenges, socio-economic limitations, or inadequate biological features of the species of interest. Yet, some of these biological features can also vary at the intraspecific level, between allopatric populations. Indeed, geographic differentiation can shape genetic, phenotypic, and ecologic specificities, which could lead to unique domestication predisposition or socio-economic attractiveness among allopatric populations. Therefore, choosing wild populations exhibiting a high potential for aquaculture (i.e. presenting interesting expression of key traits) could facilitate the domestication and production of new species.
