Estimation of Growth Parameters of the Black Scallop <i>Mimachlamys Varia</i> in the Gulf of Taranto (Ionian Sea, Southern Italy)
The present study examines the juvenile growth of nine cohorts of <i>Mimachlamys varia</i> in a coastal area of the Ionian Sea, from January 2014 to May 2015. The results showed that <i>M. varia</i> could reach commercial size in less than one year of cultivation, but signifi...

| description | The present study examines the juvenile growth of nine cohorts of <i>Mimachlamys varia</i> in a coastal area of the Ionian Sea, from January 2014 to May 2015. The results showed that <i>M. varia</i> could reach commercial size in less than one year of cultivation, but significant differences in absolute growth rate (AGR) and specific growth rate (SGR) were found among cohorts (<i>p</i> < 0.05). Relationships between scallop growth (size and weight) and environmental variables (water temperature, dissolved oxygen and chlorophyll concentration) were also identified. The length–weight relationship showed negative allometric growth and indicated high correlation with R<sup>2</sup>, ranging from 0.95 to 0.82. Von Bertalanffy growth parameters showed the highest values of L<sub>∞</sub> in the cohorts collected in January, April and February (52.2, 51.2 and 50.3), respectively. The growth performance index (φ’) ranged between 2.52 (cohort collected in June) and 3.03 (cohort collected in August). The obtained data add basic knowledge to the growth performance of this species, making this a good opportunity to facilitate aquaculture diversification in this part of Mediterranean Sea. |
