Secondary metabolites produced by cyanobacteria and other microorganisms include odorous compounds that can taint aquaculture products, rendering them unsalable. Many wild and cultured fish species are affected by off-flavour. Herein, we describe off-flavour occurrence in rainbow trout raised in a recirculation trout production system in Denmark. Smoked fish from two facilities contained MIB concentrations as much as 100X sensory threshold levels.
