Abstract
A population of the Asian date mussel Musculista senhousia (Mollusca, Bivalvia) was monitored over time in the Sacca di Goro (Ferrara, Italy), where it was first detected about a decade ago. The population was numerically dominated by a single cohort of individuals for most of the year. Summer dystrophic crises reduced of 90% mussel abundance. A specific growth curve was calculated by using the bertalanffian model. Secondary production was also estimated; P/B ratio was 1.9File in questo prodotto:
