The concentration of BMAA in SF and MF. BMAA was detected only from 11 out of 12 biological replicates of MF. “Number” indicates the number of biological replicate accumulating BMAA. BMAA concentrations are calculated from 11 out of 12 biological replicates containing BMAA. BMAA concentrations are expressed as µg BMAA/g DW ± SE. SF, standard feed; MF, mixed fodder with standard feed and mussel meat.
