“…Linear extension rates also indicate the required time to reach a determined marketable size 14 . Highlighting the size-age relation is crucial to enforce correct management strategies 15 . The calcareous shell of many bivalves encloses an ontogenetic record in the form of annually resolved growth increments 16,17 and reliable and accurate information can be revealed on bivalves’ life history such as their age 17,18 .…”

“…Bivalve age can be estimated using different methods: mark and recapture experiments 17 , analysis of size-frequency distributions 19 , counting of annual growth marks or rings visible on the shell surface or in the microstructure of shell sections 17,20,21 and analysis of oxygen isotopic composition along the shell growth direction 15,22 . Visible rings and banding patterns are often formed on the shells of bivalves when they undergo periods of reduced shell growth 23 .…”

Environmental factors are encoded in shells of marine bivalves in the form of geochemical properties, shell microstructure and shell growth rate. Few studies have investigated how shell growth is affected by habitat conditions in natural populations of the commercial clam Chamelea gallina . Here, skeletal parameters (micro-density and apparent porosity) and growth parameters (bulk density, linear extension and net calcification rates) were investigated in relation to shell sizes and environmental parameters along a latitudinal gradient in the Adriatic Sea (400 km). Net calcification rates increased with increasing solar radiation, sea surface temperature and salinity and decreasing Chlorophyll concentration in immature and mature shells. In immature shells, which are generally more porous than mature shells, enhanced calcification was due to an increase in bulk density, while in mature shells was due to an increase in linear extension rates. The presence of the Po river in the Northern Adriatic Sea was likely the main driver of the fluctuations observed in environmental parameters, especially salinity and Chlorophyll concentration, and seemed to negatively affect the growth of C . gallina .

“…Several factors, including spawning, food availability, type of substratum, depth, light, temperature, salinity and population density may affect shell growth rate (Gaspar et al, 2004;Dalgiç et al, 2010). Growth is the result of linear extension along the umbonal-ventral axis per unit of time, and slows down with increasing age or size (Lorrain et al, 2004), as also confirmed by isotope analysis (Keller et al, 2002;Mancuso et al, 2019).…”

“…Studies of bivalve population dynamics require a thorough knowledge of their growth rate and age and are essential to develop effective fishery management measures (Mancuso et al, 2019). Age and growth have extensively been investigated for bivalve mollusks in different geographical areas with a variety of methods, including mark and recapture (Jones et al, 1978;Ropes et al, 1984;Adjei-Boateng and Wilson, 2013), size-frequency distribution analysis (Froglia, 2000;Herrmann et al, 2009), shell surface growth rings (Fiori and Morsán, 2004;Adjei-Boateng and Wilson, 2013), thin sections (Christian et al, 2000;Dalgiç et al, 2010), acetate peel replicas (Ramón and Richardson, 1992;Gibson et al, 2001;Gaspar et al, 2004;Masu et al, 2008) and isotope analysis (Keller et al, 2002;Mancuso et al, 2019).…”

Age and Growth of Striped Venus Clam Chamelea gallina (Linnaeus, 1758) in the Mid-Western Adriatic Sea: A Comparison of Three Laboratory Techniques

Age and growth studies provide critical data for clam fishery management. Three aging techniques, thin sections and acetate peel replicas-which involve shell sectioningand surface growth rings were used to estimate the age and growth of Chamelea gallina populations in the mid-western Adriatic Sea. Their results were compared to identify the most reliable and least time-consuming approach. There were no significant differences between the two shell sectioning techniques (χ 2 = 4.66, df = 3, p = 0.198), which were described by the same von Bertalanffy (VBF) growth curve parameters (L 8 = 43.9, k = 0.26, t 0 = −0.84), whereas significantly different L 8 and k values were found between the two shell sectioning techniques and surface growth rings (L 8 : χ 2 = 13.62, df = 1, p < 0.001; k: χ 2 = 9.18, df = 1, p < 0.002; these statistics refer to the comparison between acetate peels and surface growth rings). The latter approach proved unreliable and error-prone, as it underestimated age and overestimated the growth rate (L 8 = 26.4, k = 1.91, t 0 = −0.11). Although the thin sections and acetate peel techniques both provide reliable age and growth estimates, the former approach was less time-consuming. Our analyses demonstrated that shell growth is slower in the cold season and in older specimens and that it has slowed down over the past few decades.

[1] We present here a potential new method to evaluate past variations of the mean intensity of Peruvian coastal upwelling and of the seasonal timing of phytoplankton blooms. This method uses a combination of the monthly carbon and oxygen isotopic signals preserved in fossil mollusk shells, and a series of corrections Copyright 2012 by the American Geophysical Union 1 of 17 to extract the variations of the dissolved inorganic carbon (DIC) d 13 C. Based on the analysis of five shell samples (85 shells in total) from the southern Peruvian coast, we suggest that the mean coastal upwelling intensity can be determined from a linear relationship between average values of corrected shell d 13 C and d 18 O. This new potential proxy would bring additional independent information valuable to interpret paleoproductivity changes reconstructed from marine sediment of the nearby continental shelf. Results obtained on fossil samples from the middle Holocene show an increase in upwelling intensity during this period associated to a spatial reorganization of upwelling centers along the South Peruvian coast. At the seasonal scale, corrected shell d 13 C enrichment indicates a phytoplankton bloom. Seasonal timing of phytoplankton blooms can be estimated by the lag with the annual temperature cycle reproduced by shell d 18 O monthly variations. The results obtained with two modern shell samples indicate phytoplankton blooms occurring during summer and fall, consistently with in situ productivity observations. Our method relies on revisited assumptions about the influence of temperature and metabolism in mollusk shell d 13 C. We further discussed the validity of these assumptions and the potential implications for the interpretation of similar data sets.
