Accrescimento in long-line diMytilus galloprovincialisLmk. nello stagno di Calich (Sardegna nord-occidentale) = Growth of long-line culturedMytilus galloprovinciallsLmk. in the Calich Lagoon (North-Western Sardinia)

The Mediterranean musselMytilus galloprovincialis(Bivalvia, Mytilidae) was long-line cultured in two different areas of the Calich Lagoon (NW Sardinia, Italy). Several physical and chemical water parameters, chlorophyllaand sedimentation rate were measured in the two culture stations and in a third considered as a control. Mussel growth rate was similar in the two stations. It was positively affected by the increase of water temperature and chlorophyllaconcentration and negatively by oxygen depletion.
