Table 1 PERMANOVA main test F values (with associated significance in brackets) between the different treatments of Ruditapes decussatus (Rd), Ruditapes philippinarum (Rp) (8 Rd + 0Rp, 6 Rd + 2Rp, 4 Rd + 4Rp, 2 Rd + 6Rp, 0 Rd + 8Rp) and between the control (C) and each ratio separately for maximum (f-SPILmax), median (f-SPILmed) and mean (f-SPILmean) mixed depth of particle redistribution (mm), and SBR (mm) at D21. The SBR was not calculated for the control aquaria (n.a).
