  Abstract

The fan mussel Pinna nobilis is a rapidly growing suspension-feeding bivalve endemic to the Mediterranean Sea and usually inhabits seagrass meadows. This endangered bivalve assimilates carbon and nitrogen isotopic ratios in tissues from its food sources. The {delta}13C and {delta}15N signatures were used to demonstrate isotopic variation among three tissues (digestive gland, gills and muscle) and (for digestive gland and gills) between summer and winter. Isotopic values were in the order: gills {approx} muscle > digestive gland. The mean values of the isotopic signal for {delta}13C were –20.41 ± 0.12{per thousand}, –19.78 ± 0.07{per thousand} and –19.30 ± 0.5{per thousand} and for {delta}15N were 2.84 ± 0.11{per thousand}, 4.05 ± 0.14{per thousand} and 3.51 ± 0.15{per thousand} for the tissues digestive gland, gills and muscle, respectively. Seasonal variations (summer–winter) were found in the isotopic signals ({delta}13C and {delta}15N) for digestive gland and gills of fan mussel. As a result, this study suggests muscle as the appropriate tissue for future trophic studies and indicates that isotopic signals should be compared in the same season. These {delta}13C and {delta}15N values are among the first available for P. nobilis and contribute to the library of {delta} values for marine invertebrates.
