Heatmaps showing the top 20 metabolites that differed significantly (p < 0.05) in (a) gills and (b) adductor muscles among treatments (Con = control, Post-H = mussels after post-harvest simulation, MgCl2 = mussels after two-hour MgCl2 immersion, and 14 °C and 4 °C = mussels after two-hour immersion in 14 °C and 4 °C seawater, respectively). Columns represent replicate samples and each row represents an individual metabolite. The colour varied from dark red to deep blue representing high to low values of metabolite concentrations. Metabolites were grouped into four clusters in gills and three clusters in adductor muscles, which are involved in energy metabolism, amino and fatty acids metabolism, and cellular stress response
