Eggs are laid from April to August, when water temperatures are above 13 °C. The eggs are released above the substrate and drift with the current before adhering to the bottom.[1] The larvae and juveniles feed on detritus on the bottom.[2] The fingerlings grow to some 12 cm (4.7 in) in the first year and this fish can live for up to five years. The species is much valued for its delicate flavour.
