“…For instance, some fish species display low resistance to diseases or low food conversion efficiency, which impede or slow down their domestication (Liao and Huang 2000;Otton 2004). Conversely, other traits are favouring domestication such as fast growth rate and acceptance of artificial feeds, and consequently make taxon production an economically viable initiative (Liao and Huang 2000;Le François et al 2010). Among these features, some behavioural traits are particularly essential since they can deeply facilitate domestication (Liao and Huang 2000;Jobling 2010; Le François et al 2010) and subsequent aquaculture production (Huntingford et al 2012).…”

When behavioural geographic differentiation matters: inter-populational comparison of aggressiveness and group structure in the European perch

Domestication is still a long and difficult process and it is particularly impacted by species behavioural traits. Indeed, tolerance to high densities in intensive cultures and sociability are major features which facilitate domestication and influence the effectiveness of aquaculture production. Moreover, behavioural domestication predispositions could change at the intraspecific level. Here, we investigate three essential behavioural traits: aggressive interactions, group structure, and activity between three allopatric populations of Perca fluviatilis, a fish species at its nascent stage of production. We highlight inter-populational differences in group structure and aggressive interactions but not in activity. A more cohesive and homogeneous group structure was demonstrated for Finnish populations compared to Lake Geneva at 45-46 days post-hatching. In addition, Lake Geneva presented a higher aggressiveness. These inter-populational differences could be used in European perch aquaculture in order to improve production as well as welfare of individuals.

“…The main reason why numerous attempts with new species fail is that premature attempts to develop industrial enterprises were based on overly optimistic speculation about market demand, rather than on biological and technical knowledge and adequate information about economic feasibility (Jobling 2010).

Levels of domestication in fish: implications for the sustainable future of aquaculture

The agricultural world today is dominated by a few domesticated mammal species, that is, animals modified from their wild ancestors through selective breeding in captivity for traits beneficial to human usages. As a result, a clear dichotomy exists between wild (from hunting) and domesticated mammals (produced in farms) used for human consumption. Similar to agriculture, aquaculture is often viewed as the only solution that can provide more fish products given that harvesting wild stocks have reached an upper limit. Aquaculture is considerably younger than agriculture relying on natural sources to farm numerous species. To better describe the diverse strategies for fish production, we propose a new classification comprising five levels of ‘domestication’ with 1 being the least to 5 being the most domesticated. Our classification places 70% of the 250 farmed finfish species recorded in the 2009 FAO database into levels 1, 2 and 3 representing a transitory form of fish production dependent on the availability of the wild resource. In contrast, only a few species, or more accurately populations, can be considered truly domesticated, similar to cattle or sheep. Based on this classification, two scenarios for the future of aquaculture are discussed: either the industry focuses on few truly domesticated species, similar to the path taken by agriculture, but avoiding its negative impacts or aquaculture proceeds with inter‐specific diversification by focusing primarily on the domestication of native species.

This selection has been further reinforced by a survey conducted among Percids and Sturgeons producers.…”

“…Besides the species intrinsic aquaculture potential, domestication of a taxon is unlikely if the human needs that it could meet are already addressed (e.g. by other currently domesticated species; Le François et al 2010, or when capture fisheries already fulfil consumer demand for a particular species, e.g. Otterå 2004).…”

Domestication of new candidate species remains a long and difficult process often resulting in unfruitful attempts. Early steps in most domestication programmes 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 socio‐economic 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 standardise and facilitate new domestication attempts by taking advantage of wild geographic differentiation. Step 1 consists of classifying the wild biodiversity to identify prospective units (i.e. groups of differentiated allopatric populations). Step 2 allows comparing performances of these units in standardised conditions (i.e. rearing system) through a multifunction and multi‐trait assessment. Finally, 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.

Considerations for the selection and commercialization of new or alternate species.

Abstract: This chapter discusses the factors, criteria and reasons that must be considered in the selection and commercialization of new or alternate aquaculture species with focus on its marketability and profitability.
