Initial methods for ageing Atlantic Mud-piddock (Barnea truncata) / Dale Roddick and Caira M. Clark. : Fs97-6/3312E-PDF
"The Atlantic Mud-piddock, Barnea truncata, is listed as a threatened species in Canada, where the only occurrence is a small disjunct population in the Minas Basin of Nova Scotia. This initial study of age and growth for this population was restricted in sample sizes due to the status of the species, but shows that they can be aged using growth lines in hinge to posterior cuts of the shell. Thin sections can be used forageing, but etching and staining increases readability of the growth lines. The resulting growth curve is the first recorded for this species, and shows that the Minas Basin population has a lifespan of approximately 11 years. The first ring is deposited at around 6 mm shell length"--Abstract.
