PHOTOS: Over 100,000 Coho Salmon Fry Introduced Into Local Streams
This past Saturday (Jan 22) volunteers gathered at the Miller Creek plant of the Southwest Suburban Sewer District. Equipped with coolers of all shapes and sizes, their mission was to transport the more than 100,000 salmon fry hatched here to creeks in the local area.
The tiny salmon arrived at the hatchery here in mid-December as eggs from the Soos Creek Hatchery operated by the Washington Department of Fish and Wildlife.
For the last month they’ve been watched over by volunteers under the guidance of members from the local chapter of Trout Unlimited, who manage the local hatchery operation. During this period these volunteers combed through incubation trays looking for dead and diseased eggs.
Eventually the fish hatch and absorb their yolk sacks. Now they’re ready to be introduced into local streams.
Compared to other hatchery operations, these Coho salmon fry are being released into the wild earlier in their life cycle. The benefit is that this causes them to be exposed to many of the same environmental pressures as their wild counterparts. While up to 90% of the newly released fry will perish, those that survive will be stronger and healthier.
