Reckoning with the Real ROI of Chambers Creek Steelhead Programs
Hatcheries are widespread across the Pacific Northwest, but their heavy use remains controversial for a host of genetic, ecological, and economic reasons. Interbreeding between hatchery and wild salmonids can reduce genetic diversity and homogenize population structure. Meanwhile, billions of hatchery fish may be overgrazing the North Pacific.
But there’s also a growing concern about the financial return on hatchery investments. A recent Columbia River study examined the return on investment (ROI) of a 19-year hatchery program intended to boost Chinook salmon populations (Jones et al. 2021). Between 1998 and 2009, the program released nearly one million smolts. It produced 685 adults that passed Bonneville Dam — but only 61 returned to spawn in their home river. The total program cost over $28 million.
That equates to roughly $459,000 per adult that returned to its natal river.
While those numbers are at the extreme end of the spectrum, they raise serious questions about hatchery economics — not only in terms of dollars per fish, but also in terms of overall program goals and food return.
Of course, not all hatchery fish are released for conservation. Many, like Chambers Creek winter steelhead in Puget Sound, are planted to support recreational and commercial harvest. In 2024, Puget Sound hatcheries released approximately 660,000 winter steelhead smolts and 140,000 summer steelhead smolts into regional rivers. But smolt-to-adult return rates (SARs) have declined sharply, with recent estimates ranging from 0.5% to 1.5%.
What happens if we look at hatchery ROI not in dollars — but in pounds of edible fish?
The Math of Poor Returns
If 100,000 smolts are released, and SARs range from 0.5% to 1.5%, we get 500 to 1,500 returning adults. Most of these fish mature after a year at sea, reaching lengths of 24–26 inches and weighing around 6 pounds on average.
That yields between 3,000 and 9,000 pounds of returning adult steelhead.
But here’s the catch: hatchery smolts themselves weigh about 80 grams (0.17 pounds) each. That means 100,000 smolts represent 17,000 pounds of fish before they ever enter saltwater.

A Thought Experiment
Many factors contribute to poor marine survival of hatchery steelhead. But regardless of cause, SARs are now so low that it’s worth asking a blunt question: Could we feed more people by eating the smolts instead of waiting for adults to return?
An average serving of fish is about 6 ounces (0.38 lbs).
At that rate:
From a food perspective, the current return on hatchery investment is wildly inefficient.
Table 1. Number of people fed by steelhead (steelhead meals) and smolts (smolt meals) for every 100,000 smolts released in relation to varying smolt-to-adult survival rates (SAR) of 0.5%, 1.0%, and 1.5%.
From Fisheries to Food
I’m not seriously proposing we start eating hatchery smolts.
But the numbers expose the stark inefficiency of these programs. Chambers Creek steelhead are meant to support fisheries and feed people — but instead, we’re producing calories for predators, from mergansers and cormorants to harbor seals and otters. If they had a vote, they’d raise a wing or flipper in support of hatchery expansion.
In reality, we’re losing more protein than we gain by releasing these smolts into Puget Sound.
A Broken Investment Strategy
Puget Sound hatchery programs continue to spend millions raising fish with less than 1% survival, even as wild steelhead populations collapse. This isn’t just ecologically bankrupt — it’s fiscally irrational.
We’d never tolerate this kind of return in a retirement portfolio. Why do we accept it in fisheries management?
So maybe it’s time to ask: Are we trying to feed people, feed predators, or feed outdated ideas?
If hatchery smolts are mostly ending up in the stomachs of animals, then maybe the most honest thing we could do — metaphorically — is serve them with a side of fries and admit the system is broken.

An average serving of fish is about 6 ounces (0.38 lbs).
At that rate:
- 100,000 smolts could produce 44,737 meals
- 100,000 smolts yielding 500–1,500 adults would produce just 7,895 to 23,684 meals
