Experimental Manipulations Of The Organic Chemistry Of Seawater: Implications For Studies Of Energy Budgets In Marine Invertebrate Larvae, William Jaeckle

Correct measurement of changes in biomass and metabolic rates over time are two essential elements for the accurate construction of energy budgets for invertebrate larvae. Both components of larval energetics are altered by changes in the organic chemistry of the seawater. Axenic (bacteria-free) veliger larvae (88 µm shell length) of the bivalve Crassostrea gigas (Thunberg, 1795) had a 53% enhancement of their metabolic rate relative to control values (5.8 ± 0.6 pmol larva -1 h -1 , x¯ ± 1 SE) when exposed to seawater to which 1 µM glucose had been added. Gastrulae increased their rate of respiration by …
