Density-dependent effects on morphological plasticity of Mytilus gallloprovincialis in suspended culture

►Morphological plasticity in cultured mussels was analyzed along a density gradient. ►Differences in morphological ratios (H/L, W/L and H/W) due to density were observed. ►No influence of culture density on the energy distribution (CI) was detected. ►Volume-Length and Area-Length allometries suggested asymmetric competition processes. ►Morphological plasticity mitigate the effect of intra-specific competition in mussels.
