Sourcing

Named species.
Named waterway.
Named program.

Every Fallow protein is sourced from an invasive species operating under an active removal program. "Responsibly sourced" is not enough. We name the species, the waterway, and the reason — on every bag.

Specific

Named species. Named waterway. Named program. Not "responsibly sourced."

Verifiable

Every bag carries a harvest code traceable to a licensed removal operation.

Net-positive

Harvesting these animals reduces ecological damage. The supply is encouraged.

Active sourcing

Silver Carp

Hypophthalmichthys molitrix

Native to eastern Asia · Illinois River

Silver carp were introduced to US aquaculture ponds in the 1970s to control algae. They escaped into open waterways during flooding and established themselves across the Mississippi basin with no natural predators to slow them. They now comprise up to 90% of fish biomass in some stretches of the Illinois River — outcompeting native species for food and oxygen at a scale that has reshaped entire waterway ecosystems.

Ecological impact

A single adult silver carp filters up to 20% of its body weight in phytoplankton daily — starving native filter-feeders, disrupting the base of the food web, and driving down native fish populations that have existed in these rivers for thousands of years. Illinois DNR runs active commercial removal operations year-round. The supply is not only abundant — its removal is actively encouraged by state and federal fisheries programs.

Why it works for dogs

Extremely high in protein (38g per 100g) and omega-3 fatty acids (2.1g DHA+EPA per 100g). Low in heavy metals compared to most ocean fish. The meat texture lends itself to multiple treat formats — air-dried strips, soft training bites, and freeze-dried single-ingredient pieces — all from one traceable supply chain.

Invasion range

Where they've spread —
and where we source.

1970s — Introduction

Silver carp imported to Arkansas aquaculture facilities for algae control. Escape events during flooding allow them into the Mississippi River.

1990s–2000s — Spread

Population expands rapidly through the Mississippi and into the Illinois River. Native fish populations decline. Federal programs begin targeting removal.

2010s–present — Established

Silver carp now dominate large stretches of the Illinois and Missouri Rivers. The Illinois River alone targets removal of ~7 million lbs per year. This is Fallow's supply chain.

Why this matters for supply

The scale of the invasion means supply is not a constraint — it's a resource. Illinois River commercial removal fisheries operate year-round under state mandate. Every pound purchased creates direct economic demand for continued removal. That's the model.

How it works

From removal program
to your dog's bowl.

01

State removal programs

We source exclusively from fisheries and hunters operating under active state and federal invasive species removal programs. Every batch is traceable to a licensed removal operation — Illinois DNR, Missouri DOC, USDA Wildlife Services.

02

Single-ingredient processing

No fillers, no binders, no additives. The animal is the product. Dried at low temperature to preserve protein and omega-3 content. Processed in USDA-inspected facilities.

03

Batch traceability

Every bag carries a harvest code. Scan it to see the waterway, the removal date, and the program it came from. If we can't say where it came from, it's not in the bag.

04

Packaging

Kraft paper bags with a compostable inner liner. No plastic zip-locks. Printed with soy-based ink. We're working toward fully home-compostable packaging by 2027.

"We work with Illinois River fisheries that target invasive carp as part of state removal programs. Every batch is traced to the harvest location. If we can't say where it came from, it's not in the bag."

Limited invasive drops

Small-batch editions,
released when supply allows.

Silver carp is the backbone of the line — abundant, traceable, and net-positive for the ecosystem. Beyond carp, other invasive proteins each carry their own story. Supply is thinner and seasonal, so these rotate in as small-batch drops, not catalog staples.

Gulf Coast wetlands

Semi-aquatic rodent introduced for fur farming. Destroys marsh ecosystems by eating plant roots, leaving bare mud flats. Louisiana alone has 20+ million. High in lean protein.

Central & Southern US

Causes an estimated $2.5B in agricultural damage annually. Actively hunted year-round in most states. High-fat, high-protein — naturally suited for a high-value treat.

Lionfish

Pterois volitans

Atlantic coast, Gulf of Mexico

Invasive to Atlantic reefs since the 1980s. No natural predators. Devastating to reef fish populations. Delicious, high in omega-3 — currently underutilized.

South Florida

Widespread throughout South Florida. Damages infrastructure, displaces native wildlife. Florida FWC actively encourages removal. Novel protein with an unusual sourcing story.
