What We Do
At Grist Goeson Memorial Hatchery, we are committed to supporting the Coquitlam Watershed
and Ecosystem with a primary focus of sustaining and enhancing fish populations, and to
ensure the health and vitality of future fish generations.
Our dedicated team of volunteers engage in a multitude of tasks that range from broodstock
capture to fry releases, ensuring a comprehensive approach to fish hatchery management, in
partnership with the Department of Fisheries and Oceans (DFO), B.C. Hydro and the
Kwikwitlem First Nation.

Seasonal Activities
Broodstock Collection
Our broodstock collection occurs during the months of October and November. This crucial
activity involves collecting mature adult fish from the Coquitlam River, primarily by angling.
Eggtake & Incubation
From capturing broodstock, we move into the eggtake and incubation phase, which takes place
in November and early December. During this phase, eggs are carefully harvested from the
captured broodstock , fertilized, and placed into incubation trays where they are monitored and
cared for until they are hatched then ponded.
Egg Picking
Egg picking is a meticulous task that occurs from January through April. Volunteers and DFO
engage in weekly sessions to sort through incubating eggs, removing any that are not
developing properly to ensure optimal hatching success rates.
Marking
Late July or early August marks the time for fry clipping. This process involves clipping the
Adipose Fin, the smallest fin on the fry, for identification purposes, which helps in tracking and
studying the fish once they are released into the wild and support the local “recreational fishery”.
Release
Our fry release activities span June, July, and early August. During this period, we release the
young fish into the Coquitlam Watershed, supporting the natural fish populations and
contributing to the ecological balance of the area.
Weighing
On a scheduled basis, monthly or seasonally bi-weekly, the “Weighing Team” conducts fry
weighing to monitor the growth and health of the young fish. This data is crucial for adjusting
feeding and care practices to ensure the best outcomes for the fish.
Feeding
Feeding the fish is a daily task, managed through a bi-weekly “single day” rotation system. Each
feeder works with a partner, alternating one weekday every second week. This consistent
feeding schedule ensures that the fry receive the proper nutrition needed for healthy
development.
Site & Equipment Maintenance
Year-round, we perform regular maintenance of the hatchery site and its equipment. This
ensures that our facilities are in top condition to support our various activities and provide a safe
and efficient working environment.
Special Projects
Throughout the year, we also engage in special projects that may arise, contributing to the
improvement and innovation of our hatchery operations. These projects involve various
activities and often require the collaboration and creativity of our team with offsite resources.
By participating in these seasonal activities, the Grist Goeson Memorial Hatchery plays a vital
role in conserving and enhancing our local fish populations. Our efforts not only support the
environment but also educate and involve the community in sustainable practices.
