Dear All, March 24, 2007
While sweeping rotting grass and debris in transient pools of a
drainage ditch today I encountered hundreds of small bivalves (~1-2 mm
long; dirty yellow, translucent and darker near the hinge), presumably
young freshwater clams of some kind.
Logically, freshwater clams would spawn early in the spring, so that
the mobile phase would have maximum chance of reaching wet pools that
are cut off later in the summer. If this is in fact the case (does
anyone know when they do spawn ?) then are these clams at least 12
months old or can they grow rapidly enough to be this year's crop ?
