Education - Let's Go Outside!
When is the best time to visit the hatchery?
The hatchery is open for visitors Monday through Friday 7 AM to 3 PM. During the months of May through September the hatchery is open on weekends
from 11 AM to 3 PM . The best time to see returning adult salmon is from September
through the end of October. If you are in the area, you can see the
different stages of egg incubation by revisiting the hatchery.
Do you give tours of the hatchery?
We give tours of the hatchery to schools and other groups usually
during the fall when adult salmon are returning, and when are collecting
eggs from them. Please contact the hatchery to schedule a tour at 360-765-3334
or 3330, or you can send an email to email@example.com
When do you spawn the adult salmon?
Coho salmon spawning at Quilcene NFH starts the first week
What does "Anadromous" mean?
Anadromous refers to a fish species that lives part of their life in fresh
water then moves to the ocean to mature before returning to fresh water to
spawn. Coho (silver) salmon spend 1 ½ years in the freshwater and
1 ½ years in the ocean. All pacific salmon die after spawning, other
species, such as steelhead and bull trout may make the transition between
salt and fresh water several times during their life.
What is a smolt?
A smolt is a juvenile salmon that has completed the physiological adaptation
and is ready to travel from fresh water to salt water
What is a redd?
A redd is the nest where the salmon lay their eggs in the river gravel. The
female salmon turns on her side and uses her tail to make a depression in
the gravel. As she lays her eggs into the depression they are fertilized
by the male and the female covers the eggs with the gravel. The eggs absorb
water in the first hour after fertilization and secure themselves in the
spaces between the gravel for incubation.
How many eggs does an adult female salmon lay?
Adult female coho salmon average around 2,500 eggs, depending in the
size of the individual fish. Chinook salmon, a larger species, can
average 5,000 eggs per adult.
How many eggs are placed into the incubators?
Vertical stack fish egg incubators contain 16 drawers holding 5,000 coho salmon
eggs with a water flow of 4 gallons per minute
What do you do when your fish get sick?
The U.S. Fish & Wildlife Service has a Fish Health Center in Lacey, Washington
, providing support to Quilcene and other national fish hatcheries in Western
Washington . Their staff includes doctors of veterinary medicine working as
fish pathologists who check the health of our fish monthly. If fish mortality
(dying) increases, we request their assistance. Based on their diagnosis, they
recommend treatment of the fish. Fish pathologists also take samples of fish
tissue and fluids from the adult salmon that are used that are used to check
What fish do you raise at the hatchery?
We currently raise coho (silver) salmon for on-station release into the Big
Quilcene river and provide fish and eyed eggs for tribal net pen programs.
A Hood Canal steelhead supplementation was started in 2007, that will
hopefully increase their survival rate.
What is a raceway?
Our raceways are concrete ponds with dimensions of 8 feet wide by 80 feet long.
Raceway numbers and dimensions vary from hatchery to hatchery.
How much water goes through one raceway?
Typically about 500 gallons per minute flows through each raceway.
How many fish are in a raceway?
The number of fish depends on the size of the fish and their environmental
conditions. Typically, numbers range from 20,000 to 75,000 fish per raceway.
What do you feed the fish?
Many fish food companies make food for different species of fish, different
sizes of fish. If the fish are sick, the manufacturers can include medicines
directly into the food with the written recommendation of the fish pathologist
Do you feed the adult salmon when they return to the hatchery?
No, adult salmon stop eating once they enter fresh water, living off their
stored body fat until they spawn and die.
What happens to the extra adult fish that you don't use for egg collection?
The U.S. Fish & Wildlife Service and several local tribes have an agreement
to provide the surplus adult fish to tribal members for subsistence. If the
tribes do no want the adult salmon, the U.S. Fish & Wildlife Service provides
these extra adult fish to the Food Bank program.
Have you raised any "listed" salmon species under the Endangered
Yes. We were part of a very successful partnership called the Hood Canal summer
chum salmon recovery project. The U.S. Fish & Wildlife Service; Quilcene
National Fish Hatchery, Washington Fish and Wildlife Office - Fisheries,
Olympia Fish Health Center, Washington Department of Fish & Wildlife, and
the National Oceanic and Atmospheric Administration worked together to increase
numbers of these fish even before they were listed as "Threatened" under the
Endangered Species Act.
A listed species, "Threatened" Hood Canal steelhead program was started
in 2007, working with numerous partners.
