A comparison of relative growth in Cerastoderma (= Cardium) edule, Modiolus modiolus, and Mytilus edulis (Mollusca: Bivalvia)
Relative growth has been studied in intertidal populations of Cerastoderma edule and Mytilus edulis and in a subtidal population of Modiolus modiolus. Size dimensions were generally more variable and shell thickness generally greater in the intertidal species. Total weight was correlated with shell...

Summary: | Relative growth has been studied in intertidal populations of Cerastoderma edule and Mytilus edulis and in a subtidal population of Modiolus modiolus. Size dimensions were generally more variable and shell thickness generally greater in the intertidal species. Total weight was correlated with shell weight in all three species but there was a progressively greater emphasis on tissue growth through the sequence Cerastoderma, Mytilus, Modiolus. These results are interpreted in terms of differences in stability between their respective habitats. Analyses of individual year classes in Cerastoderma showed a marked pattern of alternating years of good and poor growth. |
