" When I look back at the first
couple of years we had just
enough eggs to provide for
Wyoming. As we built the
population up and became
better at what we were doing we
started shipping eggs to other
states. " - Steve Diekema
In 2007 golden trout eggs from Sylvan
Lake in Montana were shipped to Story,
and the facility successfully spawned captive
golden trout in 2009.
During those early years, Story produced
just enough golden trout eggs to meet
in-state needs - around 40,000 eggs per
year. In 2022 it produced about 300,000 and
for the better part of a decade has sent eggs
to other states. This year eggs were sent to
Colorado, Idaho and Washington. In recent
years Story also has sent eggs to California,
Montana and Utah.

of years we had just enough eggs to provide
for Wyoming, " said Diekema, who has
worked at Story for 14 years. " As we built
the population up and became better at what
we were doing we started shipping eggs to
other states. "
HOW IT WORKS
Golden trout - along with brook,
brown and rainbow trout - become sexually
mature at 3 years old. Diekema and his
crew spawn males and females that are 3 and
4 years old, and sometimes some females are
held until they are 5 to bolster egg numbers.
Two age classes are always spawned
together. For example, a 3-year-old female
with a 4-year-old male. That ensures there
is not a brother-sister cross. Producing eggs
and fish is a top goal, obviously, but so is
genetic integrity.

ity eggs, but when you back it all the way
out it's all about broodstock management
first. Then, everything else falls into place, "
Diekema said.
