Growth of the fan mussel Pinna nobilis (Linnaeus, 1758) (Mollusca: Bivalvia) in experimental cages in the South Adriatic Sea

摘要

Juveniles of the fan mussel Pinna nobilis were collected in Mali Ston Bay from October to December 2006. Cages with juveniles were placed at three depths: 1, 3 and 5?m. At the end of a 2-year growth period at 1?m depths, the average length was 244.1?±?22.9?mm, at 3?m depths, specimens averaged 244.0?±?25.3?mm, and at 5?m depths, the average length was 231.1?±?22.5?mm. The average monthly growth of shell length for the total experimental period was 8.7?±?5.3, 8.4?±?4.5 and 7.6?±?4.4?mm, at 1, 3 and 5?m depths respectively.
