Growth and production of the bivalve <i>Macoma balthica</i> (Linnaeus, 1758) (Cardiida: Tellinidae) in the southeastern Baltic Sea
We studied the growth and production of Macoma balthica in the southeastern part of the Baltic Sea. The maximum shell size of M. balthica was up to 23.5 mm, the maximum age was 13+ years. Linear growth is described by the Bertalanffy equation: for shallow water (9-40 m) and for deep water (41-81 m). The annual production of M. balthica in the shallow-water area (25.35 ± 1.72 kJ/m2) was lower than in the deep-water area (71.23 ± 4.48 kJ/m2); the Рs/B ratio was 0.44 and 0.38, respectively.
