more of a motivation to do a study of their husbandry (measure mass, size,
etc) over time, now that I know that one could-in-least be "husbanded" for a
year<<<

a few of my tanks and they have not opened. Matt is right, during times of
stress, mussels will "clam" up <<<
A friend of mine did a study on the ebony shell and found that
"intentionally unfed" mussels lost 30-40% of their body mass (exclusive of
shell) after 3 months-in-15 C but mortality was low (< 5%). He guesses that
non-feeding mussels-in-higher temperatures for longer periods would have
higher losses of mass and mortality.
I could not access Todd's site, but would guess that if the bivalves
persisted for a year, they could have been feeding, and possibly growing.
