Box-plots comparing the Scope for Growth (SFG, J h⁻¹) of slow (S) and fast (F) growing mussel seed (left panel) and the Scope for Growth of subtidal (mussel raft) and intertidal (rocky shore) mussel seed gathered from the Ría Ares-Betanzos (NW, Spain).

<p>Statistical differences are indicated as *** for p<0.001 (two-way ANOVA).</p

Physiological parameters (mean ± SD) of mussel (<i>Mytilusgalloprovincialis</i>) seed from subtidal and intertidal origins.

<p>The table shows the initial values of the energy balance and the physiological parameters obtained after 5 months of maintenance the laboratory to select the individuals with slow (S) and fast (F) growth rates. The physiological measurements included the clearance rate (CR; OW:organic weight), ingestion rate (IR), absorption efficiency (AE) and absorption rate (AR), respiration rate (VO₂), ammonia excretion rate (VNH₄-N) and Scope for Growth (SFG). Physiological rates were expressed as mass-specific rates (Y_SPC) in mg of organic weight (OW).</p

Comparison of the total clearance rate (CR_total), gill area and gill efficiency (ratio of the CR_total to the gill area) obtained in slow (S) and fast (F) growing mussel seed originated from the subtidal and intertidal ecosystems after maintenance with a monoalgal diet of <i>Rhodomonas lens</i> during five months.

Mass-specific physiological components of the energy balance in slow (S) and fast (F) growing mussel seed originated from the subtidal and intertidal ecosystems and maintained under standard laboratory conditions during five months.

<p>The feeding (clearance rate: CR, and ingestion rate: IR), digestive (absorption efficiency: AE, and absorption rate: AR) and metabolic parameters (ammonia excretion: VNH₄-N and, oxygen consumption: VO₂) represent the mean ± SD.</p
