Check the site below for some insight. In a (nut)shell (ouch -- lousy pun!), it says:
"Looking at the image above you can see many concentric lines, each representing a layer of shell that the mantle has produced. Like trees, during periods of rapid growth the shell is produced quickly resulting in many growth rings which are spread fairly wide apart. During times of slow growth the layers are produced slowly resulting in the rings being set very close together. Thus each growth spurt ends with a band that is unusually dark. The space between these dark rings represents one growing season. However, unlike trees, clams have two growing seasons per year. So to estimate the age of a clam two rings equal one year."
Of course, it helps to have the image, which is on the site. I googled "growth rings mollusk" to get this site and of course others came up as well, so you might want to check and see what else is there.
Good luck and happy counting!!

Start from the centre and start counting outwards.
The no. of rings is the age of the tree in years.

Cook it good until it flakes, then count the rings.
