Dynamic energy budgets are used for the description of the energy flow through individual organisms from the assimilation of food to the utilisation for maintenance, growth, development and reproduction. In this paper, a procedure for estimation of the parameters of Kooijman's Dynamic Energy Budget (DEB) model is introduced and subsequently parameters are estimated for the following Northeast Atlantic bivalve species: the Baltic clam
Macoma balthica (L.), the sandgaper
Mya arenaria L., the cockle
Cerastoderma edule (L.), the blue mussel
Mytilus edulis L. and the Pacifc oyster
Crassostrea gigas (Thunberg, 1793). For none of the species, a complete set of parameters could be compiled. A special protocol was developed to account for missing values and to achieve consistency between parameters. Species were similar in their optimal temperature range, as reflected in a common Arrhenius temperature of 5800 K, which corresponds with a Q
10 of 2. Differences between species were observed in width of the optimal temperature range. The taxonomic relatedness between species was reflected in similar volume-specific maintenance costs, costs for growth and almost similar maximum storage density of energy. Species differed in their maximum surface area-specific assimilation rate by a factor of 6 and in the fraction of energy allocated to reproduction (ranging from 0.15 to 0.50). These differences are reflected in the maximum theoretical total shell length of the species, which varied from about 3 cm in
M. balthica, 6 cm in
C. edule, 15 cm in
M. arenaria and
M. edulis and 45 cm in
C. gigas.
