Abstract

Clearance rates, respiration rates and food absorption efficiencies of the commercially interesting subtidal bivalve Modiolus barbatus were measured at different temperatures under laboratory conditions and scope for growth calculated. Clearance rates were highest at temperatures from 20°C to 28°C, whereas respiration rate was maximal at 9°C and minimal at 26°C. Highest mean values of absorbed energy occurred at 20°C and 26°C. Scope for growth trend had negative values at 9°C, 15°C and 28°C and positive values at temperatures 20°C and 26°C. The profitable thermal window for M. barbatus to have energy sufficient for growth and reproduction corresponded to <5 months per year. Seawater temperature increases will potentially impact the ecophysiological responses of subtidal M. barbatus causing life history traits to change with important repercussions for subtidal biodiversity in the Mediterranean
