Did a wuick Google to find this interestign read, esp on page 2.
"Spawning with multiple females
is common. Females normally
release about one-half of their
eggs during the first spawn and
half of the remaining during the
second spawn. A third spawn up
to 1 month later is common.
Females average about 4,000 eggs
per pound of body weight, but the
number can be quite variable.
Reports of up to 80,000 eggs from
one female have been reported
but the average is much smaller.
Larger fish tend to have larger
eggs and therefore larger fry but
fewer eggs per pound of body
weight. Usually at spawning the
weight of eggs in females will be
10 percent or more of her body
weight. During the spawning season
the male does not eat and
many males die each year due to
their poor body condition prior to
the spawning period."
