Finding a rare gem: Identification of a wild biological unit with high potential for European perch larviculture

Potential for aquaculture can differ among allopatric wild populations of a species interest. This makes relevant to seek best candidates fish farming at the intraspecific level. Here, we compare potential population groups European perch, interest farming. More specifically, aim finding with performance in larviculture through an integrative approach that allows considering geographic differentiation domestication processes. A multi-function/trait assessment was performed on three genetically differentiated perch populations: (i) Danube, (ii) Eastern Europe, and (iii) Plain. highlighted six important traits larviculture: survival rate, swim bladder inflation deformity length hatching, mean interindividual distances, change activity following stress event. Along farmer-advice-based weighting traits, calculation score allowed identifying from Danube region as most interesting potentially overcome current bottlenecks larviculture.
