“…Internal growth bands were measured in acetate peels made of cross sections of the left valve in accordance with MacDonald and Thomas (1980) and Hewitt and Dale (1984) who studied growth in the related Mya arenaria and arctic M. truncata, respectively. We used the growth band pattern in the chondrophore since this part of the Mya shell yields the most distinct bands.…”

Annual monitoring of the benthic fauna living at the Frisian Front (southern North Sea) has shown a tenfold decrease in the dominant brittlestar Amphiura filiformis in 1993-1995. In search of evidence that this decline was caused by a change in benthic food supply, we analysed variations in the shell growth of the bivalve Mya truncata from the Frisian Front during the period of interest. For this purpose, the widths of the internal growth bands in the chondrophore of M. truncata were standardised and assigned to calendar years. Averaging the yearly band width in the period 1985-2000 among 25 individuals revealed low growth rates in 1986 and 1992. Growth of M. truncata quickly recovered after 1992, while A. filiformis densities remained at low levels. Moreover, the 1986 dip in M. truncata growth had no equivalent in A. filiformis density. We conclude that there is no direct coupling between fluctuations in density of A. filiformis and variations in growth of M. truncata. The data we collected during this study on the size and spatial distribution of M. truncata are discussed in the light of plans for the protection and conservation of long-lived benthic organisms in the North Sea.

“…A large body size may allow high numbers of eggs which perhaps favor a wide range of distribution. A lifespan of 10-12 years is considered normal on the Atlantic east coast with a maximum of 28 years reported from the Bay of Fundy (MacDonald & Thomas, 1980).…”

Mya arenaria currently occupies a wide geographical range in the northern hemisphere, on both coasts of the Atlantic as well as on the Pacific east coast. Some authors claim it also occurs on the Pacific west coast. The species originated in the Pacific during the Miocene and was already present on both Atlantic coasts in the Pliocene. However, it died out on the edst coasts of the Pacific and the Atlantic during glaciation of the Pleistocene. With the aid of man it was reintroduced to the North Sea some 400-700 years ago and to the East Pacific last century. In the 1960s it was also introduced to the Black Sea. M. arenaria invaded new habitats by different modes:(1) natural range expansion (2) intentional as plantings, (3) unintentional as a ballast species and (4) unintentional as a byproduct of oyster transplants. Properties that may fdvor its wide range of distribution and invading success are: high fecundity; planktonic dispersal stages and life stages that lend itself to unintentional transport by humans; a broad spectrum of habitat and food preference; tolerance of a wide range of environmental conditions such as salinity and temperature; longevity, and perhaps relatively large size.

“…The major problem for ageing is the specific distinction of micro growth-bands on unstained thin sections (MacDonald & Thomas, 1980). The use of Coomassie Blue was crucial for growth-band counts for this species; it facilitated clear band boundaries and helped discriminate from blurred areas in the shell of the thin section.…”

“…Internal mark use may require the preparation of thin sections using optical microscopy. Microscopic growth increases in some calcareous structures are sometimes difficult to detect after thin section preparation (MacDonald & Thomas, 1980), thus staining might be required. To the best of our knowledge, the use of fluorescent chemical calcein as an initial marker of the growingedge, combined with the colorimetric protein gel stainer, Coomassie Brilliant Blue R-250, as a dye of micro growth-bands in motherof-pearl shells (Pinctada mazatlanica, Class: Bivalvia, Order: Pterioida, Hanley 1856) has not been previously investigated.…”

Age validation is the first step to determine shellfish species age determination. This information is vital for different inferential models used in marine ecosystem management activities. In spite that various validation techniques are used for marking carbon calcium structures, the calcein marking technique for oysters had never been used for age validation in Pinctada mazatlanica. Thus the objectives of this study included: the evaluation of calcein to mark a shell growing-edge, and the efficacy of Coomassie Blue staining on posterior shell growth, to produce visible micro growth-bands that would enable age validation of juvenile mother-ofpearl oysters. Oysters were collected and cultivated at The Perlas del Cortez S. de R. L. MI. pearl-farming operation, in Pichilingue, La Paz Bay, Baja California Sur, Mexico; a total of 36 oysters (shell height 11.5-36.4mm) were injected with calcein (0.125g/L), and another 50 oysters (shell height 14.8-42.7mm) were submersed in calcein (0.4 and 0.7g/L). Shell slices of calcein-marked oysters were posteriourly stained with Coomassie Blue R-25 for micro growth-band recognition. Our results showed that Calcein marking only worked by submersion and produced a concise bright lime-green florescent band along the growing-edge with clear boundaries for both concentrations. However, marks resulted better at the lower calcein concentration (0.4g/L) with more "perfect" and "good" marks on the growing-edge (p=0.0012). Commassie Blue staining technique was successful, and allowed to conclude that one micro growth-band was laid down per day, similar to other oyster species. Mean 15-d increment of shell growth height was slightly greater at the lower calcein concentration ( =0.735mm) than at the higher one ( =0.577mm) (not significant difference, p=0.198). Calcein marking of shell growingedges and Commassie Blue staining of posterior shell growth, as a method for age validation is recommended for shellfish shell growth-band counts. This will allow back-dating for estimation of very precise colonization dates, both spatially and temporally in future work. Rev. Biol. Trop. 62 (3): 957-968. Epub 2014 September 01.
