Individual growth and somatic production in Adelomelon brasiliana (Gastropoda; Volutidae) off Argentina

Growth, age and somatic production of the benthic predator Adelomelon brasiliana were studied at the southern limit of its distribution on the South American Atlantic shelf. Stable oxygen isotope ratios confirmed annual formation of internal shell growth marks. Modal shell length of the population w...
