Pikeperch is considered as one of the freshwater fishes, with the highest potential for increasing diversity of aquaculture in Europe. Its faster growth compared to other Percids and its resilience and diversification potential make Sander lucioperca an attractive species for intensive rearing, as these traits promote the potential yields in commercial production.
While the global wild catches of pikeperch have halved since 2010, its aquaculture production has doubled in the same time and exceeded 900 tons a year (FAO, 2018). This illustrates the increasing importance of pikeperch for commercial aquafarming, but also reveals that pikeperch is still a niche-market species.
Despite its increasing importance for aquaculture, the pikeperch has so far lacked a well assembled and annotated genome sequence that would allow genome-based studies to improve its suitability for aquaculture. The elucidation of the genome (cf. Fig. 2) is a prerequisite for facilitating genome-wide research into pikeperch. It provides an impetus for genomic-based breeding studies to correlate phenotypic traits with genomic variation. Ultimately, this will facilitate the development of molecular bioindicators for sustainable regional fish farming in Germany.
