Age determination in bivalves: validation of the seasonality of shell growth bands along the European coast

Many bivalve species are of commercial importance for human consumption and, therefore, growth and productivity measurements are necessary. For the analysis of growth, correct age estimation is essential. The shell of bivalves grows through deposition of successive layers of carbonate material. This calcification process in the shell is usually a seasonal event related to temperature and food conditions, with highest calcification rates during spring-summer and lowest in autumn-winter. Some species can be aged by macroscopic analysis of the shell growth bands. However, since the deposition of carbonate depends on the environmental conditions, the use of shell growth bands for ageing needs to be validated for different areas. Therefore, this project aims to analyse age of various bivalve species in different areas along the European coast. The analysis of external and internal growth bands on the shell will be validated by oxygen and carbon isotope analysis and by using an Electron Microprobe Analyzer (EMPA). With this approach, age in species with no clear seasonal pattern in band formation, such as oysters, can also be determined. Since changes in environmental conditions are registered in the shell, the study of the shell chemistry will not only allow a study of growth in bivalves but also give an indication of the use of growth bands to access environmental changes in the benthic environment.

This project consists of three main parts:

[1] Collection of bivalve species – Bivalve species will be collected in several estuaries and along the European coast.

[2] Analysis of growth bands on the shell – The number of macroscopically visible external bands will be recorded, shells will be sectioned longitudinally through the hinge and the number and position of internal bands will be analysed.

[3] Validation of the seasonality of growth bands – This will be done by analyzing isotope ratio profiles along cross sections of the shell. Two methods will be used: [a] analysis of isotopic composition of calcium carbonate powder; [b] analysis of shell chemistry with an Electron Microprobe Analyzer (EMPA).
