Pond Boss Forums INTRO Questions & Observations LMB spawning duration

From the time the eggs are deposited until hatch/ how long is the process?

Males attempt to guard the nest
and fan the silt away from the
eggs until they hatch. If he is successful,
eggs hatch in 2 to 4 days
in the southern U.S., depending
on water temperature. The male
will continue to guard the fry
until they disperse, which may be
a period of 2 weeks or more
depending on temperatures. In
nature, most nests are lost to sunfish
predation.
Nesting success is also reduced if
the temperature drops below 60o
F. This temperature usually causes
the male to leave the nest.
Without parental care the eggs
will not hatch and predation will
be increased. The fry feed on the
yolk sac of the egg for the first
few days. At 68o F they will
develop mouthparts in about 190
hours. Fry swim up when they are
about 8 days old and begin feeding
on zooplankton (cladocerans,
rotifers, copepods). They remain
in a school, guarded by the male,
for 2 to 7 more days before dispersing.
They continue to feed on
zooplankton and add insect larvae
and fish to their diet when about
2 inches long.
Normally fry feed about every
three hours as this is the length of
time necessary for food to pass
through the gut.
