Ty Walker stands in thigh-deep clear, fast-flowing spring water from the mouth of a 150-foot-long, 10-foot-wide earthen pond, tearing via fistfuls of overgrown waterfall and aquatic grass. Tons of of mature, iridescent rainbow trout dart throughout the gravel backside as he clears vegetation from a creek-like channel that results in a big iron pipe that feeds the pond.
“Trout want loads of clear, recent oxygen to thrive,” says Walker, 34. Some grasses are good, however an excessive amount of dissolved oxygen, sluggish water move, and clogged drains can scale back, “which stresses the fish. And calm fish are wholesome fish; wholesome fish are tasty fish.”

That is a part of Walker’s annual upkeep routine Smoke within the chimney Trout Farm, which opened in 2019. He would spend the day weeding and cleansing, then gather the remainder of the fish over the following week. The pond then takes a break from manufacturing to naturally incorporate or filter extra vitamins from the ecosystem. Within the fall, it’ll once more be loaded with hundreds of child trout. They will start their lives right here, then cycle via a dozen related ecosystems—which collectively maintain greater than 20,000 fish in numerous phases of maturity—for about two years till they’re prepared for harvest.
“It takes a silly quantity of labor to do it this fashion in comparison with a big business aquaculture operation,” Walker mentioned. “But it surely’s the one approach to elevate trout that constantly style like they have been pulled recent from a mountain stream.”
That is as a result of the pond is a restored portion of a Thirties U.S. Division of Inside gravity-fed trout hatchery and analysis facility in Virginia’s Blue Ridge Mountains that was deserted within the early Nineteen Nineties as a consequence of finances cuts and remoteness. Right here, there are not any electrical pumps, plastic tanks, antibiotics, mechanical agitators, recycled water, chemical components or laptop monitoring. The water comes from a pristine, 54-degree spring that flows out of the bedrock at 2,000 gallons per minute. It’s carried to the pond via a collection of pipes and concrete raceways that simulate pure trout streams, then empties into an adjoining creek. Shell-bottom pavements are lined with native crops, surrounded by pollinator gardens and selectively managed forests. They’re full of naturally occurring microbes, bugs, amphibians and crustaceans. Walker and two workers hand-survey the inhabitants month-to-month for indicators of sickness or stress. They harvest and course of about 400 complete trout per week, then pack them in coolers for delivery to eating places and particular person prospects.
“There are loads of small-scale trout producers in the US, however that is actually a diamond-in-the-rough state of affairs,” mentioned Jesse Trushensky, a freshwater aquaculture researcher and present president of the US Trout Farmers Affiliation. Most related services both disappeared throughout the Massive-Ag-fueled blue revolution of the Fifties, 60s and 70s or are nonetheless used to complement native wild trout populations for fishing. Then there’s the manufacturing facet: The nation’s largest business producer — Boise, Idaho-based Reverence — churns out Over 22 million kilos Variety of trout a yr in comparison with Smoke in Chimney’s 120,000 give or take.
It is a small, very high-end facility working on historic infrastructure, Trushensky mentioned. “If different business services [like the Walker’s] exist, can’t be a couple of or two.”
Walker additionally touts the sustainability of smoke-in-chimneys versus typical fish-focused business aquaculture farms. On the one hand, he compares his farm’s manufacturing strategies to the inland freshwater equal of reproductive livestock farming.
“This method will undoubtedly have a web optimistic environmental influence,” Trushensky mentioned. The system works like a pure aqueduct, utilizing gravity and hydrostatic strain to maneuver completely balanced water from the limestone aquifer. It requires no electrical energy or components to function. It’s successfully a restored habitat for depleted pure fish populations the place, as rotational grazing, trout cycle via numerous enclosures as they develop and mature, assembly their wants whereas contributing to the general ecosystem. A proportion of newly hatched fish escape into close by streams, bolstering habitat and wild populations.

In the meantime, extra farm-raised trout in the marketplace means much less buoyant strain on native streams. This helps stability the rising hole in wild-caught seafood brought on by overfishing, local weather change and human inhabitants progress.
“It is an environmental win-win,” Trushensky mentioned. “You are growing stream well being and native fish populations whereas getting into an issue that is solely going to worsen over time.”
Walker appreciates sustainability and historic novelty—and advantages from each advertising and marketing and telling his trout’s story—however is extra involved concerning the high quality of the product the tactic yields. And the proof backs up his claims.
“This has wealthy, nutty, buttery decadence. It tastes clear and refreshing, like spring water,” says Patrick Parvola, analysis and growth chef at Albi, a Michelin-starred Washington D.C. eatery. “These are a number of the finest fish I’ve had a style in my profession. It rewrites what you assume is feasible for farm-raised fish.”

However regardless of all the benefits – and pretty 2,900 miles Native Wild Trout Stream- Smoke in Chimney is one in all three different business trout farms in Virginia. And others are comparatively small and promote virtually completely to household associates or native farmers markets. Which means, Trushensky estimates, about 95 p.c of the trout eaten in Virginia come from manufacturing facilities like Idaho, Washington or North Carolina.
The issue, he mentioned, stems from issues surrounding schooling.
First, most seafood customers have by no means tasted wild-caught or actually wholesome farm-raised trout, and the shortage of publicity results in a decline in demand. Second, Virginia focuses its aquaculture sources on seafood, so there are not any devoted highschool or collegiate-level academic applications for inland freshwater aquaculture. And farmers cannot pursue alternatives they do not know about.
“To place this in perspective: Once I began, I referred to as the Agricultural Extension Workplace [the state’s leading universities] And there was actually nobody who may inform me something helpful about farm-raised trout,” Walker mentioned. “I needed to depend on outdated books from the Thirties that I dug up on eBay, rangers working at hatcheries, farmers from different states and trial-and-error to determine it out.”

However Walker is silent. He and spouse, Shannon, spent a yr wading via regulatory purple tape and opened a small USDA-inspected processing plant close to the farm. They work tirelessly with social media and eating places to coach diners concerning the virtues of wholesome, farm-raised trout.
Walker has joined the Virginia Division of Agriculture and Shopper Companies Aquaculture Advisory Board and is negotiating with directors of the brand new Virginia Tech aquaculture and seafood manufacturing facility. He’s utilizing the place to advocate for and entry to elevated sources round gravity-fed inland freshwater aquaculture. He envisions a future the place Smoke within the Chimney has expanded to incorporate one to 2 dozen sister farms and helped dramatically enhance trout consumption throughout the state and the Mid-Atlantic.
We’ve got “pure sources and market potential,” Walker mentioned, noting $67.5 million in 2018 gross sales to the USDA Solely on farms within the high two US trout producing states. “What we’d like is help to assist get the ball rolling and notice that potential. And I do not plan to give up till it does. I need to remind Virginians why trout is our state fish.”
