Addressing Invasive Carp and Boosting Economic Development through Market-based Solutions

The document argues that while total eradication of invasive carp in the Mississippi River Basin is unlikely, creating sustained market demand—particularly in the growing US pet food sector—can suppress carp density, reduce the risk of spread into the Great Lakes, and improve biodiversity. It highlights the need for a robust supply chain that supports commercial fishers through innovative business models like co-ops and 'hub and spoke' processing. The report also outlines a plan to scale these market-based approaches to other invasive species through a new framework for assessing economic and ecological potential.

• Invasive carp, including silver, grass, black, and bighead species, have caused severe environmental and economic damage in the US, with some estimates suggesting they make up to 95% of biomass in parts of the Mississippi and Illinois Rivers.
• North America has spent over $26 billion annually since 2010 to combat invasive species, including carp, primarily through physical barriers and contracted harvests, with limited success.
• The US pet food market, valued at $59.74 billion in 2024, presents a significant opportunity for carp sourcing as the demand for pet food is outpacing the availability of human consumption byproducts.
• Carp could serve as a sustainable alternative to other proteins in pet food, potentially replacing overfished wild-caught 'white fish' or plant proteins like soy, which are facing increased demand from the alternative fuels sector.
• Ecological analysis indicates that while total eradication of carp is 'extremely unlikely' due to their high fertility and adaptability, moderate harvest levels can reduce invasion risk to the Great Lakes and restore native biodiversity.
• Commercial fishing in the Midwest is in decline, with a significant gap between the revenue generated from carp (10-15 cents per pound) compared to native species like catfish (50-60 cents per pound).
• To ensure a stable supply chain, the report suggests adopting innovative business models such as fisher-owned co-ops, 'hub and spoke' processing models, or perpetual purposeful trusts (PPT).
• WWF is implementing a two-pronged strategy: supporting the company Chippin to establish a carp processing plant and launching an Edible Invasives Initiative (EII) to coordinate the marketing of invasive species like carp and blue catfish.
• A proposed 'river-to-school' pathway aims to integrate invasive carp into K-12 school lunches, leveraging the fact that minced products (like fish sticks) bypass the hurdle of carp's bony structure.
