Roe is fish eggs. ----
Roe is fish eggs, yes, but in this circumstance I believe "roes"
is referring to roe deer. http://en.wikipedia.org/wiki/Roe_deer, as
in a "herd of roes" "Roe" when referring to the eggs of a fish
doubles as the singular and plural, like fish and deer and you get
the point. "Waiter, bring me shad roe."
