![]() ![]() Beside new domestication instances, wild intraspecific differentiation can also be used to enhance old-established species farming, because introduction of adaptive traits (i.e. growth rate, disease resistance) between wild populations allowed identifying those with higher performances which were then used as cornerstone fish stock of salmon production. Initial comparisons of several key traits for fish farmers (e.g. Similarly, the development of the Atlantic salmon ( Salmo salar) industry was facilitated by reaping the benefits from inter-populational differentiation. At the beginning of its production, bumblebee breeders tried to rear several wild populations and, eventually, identified one with superior characteristics, triggering a flourishing development of the bumblebee production industry. For instance, the buff-tailed bumblebee ( Bombus terrestris), which has been domesticated to act as pollinator in greenhouses, displays phenotypic differentiations between allopatric wild populations for traits impacting its ability to be industrially produced and to pollinate valuable crops. Several success-stories have highlighted the interest of considering inter-populational specificities. Therefore, considering population specificities could allow identifying population(s) which might facilitate farming of a new species. Indeed, populations undergoing inter-populational differentiation process can also present divergent expressions of key traits, which are essential phenotypic traits for domestication and subsequent production (see examples of key traits for fishes in ). Often considered in evolutionary and conservation biology, analysing and exploiting inter-populational differentiation is also of crucial interest for agriculture development. It results from specific demographic history, limited gene flow, random genetic drift, and/or local adaptations. Inter-populational differentiation is the divergence between allopatric, peripatric, or parapatric conspecific populations (e.g. Conclusionįor future domestication trials, we suggest using a multi-proxy assessment along with a prioritisation strategy to identify population pairs which are of interest for further evaluation in bioassays. However, no proxy was correlated to all inter-populational divergences in KTA. We showed differences in the correlation degree between the alternative proxy-based and KTA-based distance matrices, with the genetic proxy being correlated to the highest number of KTA. We performed this evaluation on seven allopatric populations of Perca fluviatilis for which divergences in KTA had already been shown. Here, we assessed the relevance of three alternative proxies: (i) genetic distance, (ii) habitat divergence, and (iii) geographic/hydrologic distances. The use of such proxies would allow to identify, prior to bioassays, the wild population pairs which are likely to present differentiations in KTA expressions in aquaculture conditions. Therefore, proxies highlighting inter-populational divergences in KTA are needed. important for domestication and subsequent production) expressions is not feasible. However, comparing all populations across a species range to identify those exhibiting suitable key traits for aquaculture (KTA i.e. ![]() Considering wild inter-populational phenotypic differentiation can facilitate domestication and subsequent production of new species. ![]()
