About Silver Carp

Silver carp is a freshwater fish, sometimes marketed as Copi, that pet food makers use as a lower-cost, sustainably positioned fish protein.

Silver carp is used in pet food primarily as an affordable animal protein and source of omega‑3 fatty acids, often included as whole fish or fish meal to provide essential amino acids and improve palatability. It can support skin, coat and joint health, but fish can be a potential allergen and its nutritional quality and safety depend on sourcing and processing, so choosing products from responsibly tested suppliers is advisable.

Whole silver carp (Hypophthalmichthys molitrix) or silver carp meal
Primary role
Alternative animal protein source, positioned as an invasive-species and lower-mercury fish option

Why it's used

Silver carp is a fast-growing, plankton-eating freshwater fish that is abundant and inexpensive to harvest, in part because it is an invasive species in parts of the United States that wildlife agencies are actively working to control. Because it feeds low on the aquatic food chain, it is discussed in industry and academic sources as accumulating less mercury than large predatory fish, and it supplies complete protein with amino acids along with omega-3 fatty acid content.

Common concerns

  • Fish as an allergen category Fish is one of the more commonly identified food allergens in dogs and cats, and cross-reactivity between different fish species has been documented in allergy research, meaning a pet reactive to one fish protein may also react to others, including silver carp.
  • Contaminant testing depends on sourcing Independent testing of pet foods has found detectable levels of mercury and other heavy metals in some fish-based diets, with levels varying by fish species and sourcing. Low-trophic fish like silver carp are discussed as a lower-mercury option relative to large predatory fish, but this depends on the specific supplier's testing practices since there is no universal contaminant limit specific to pet food.
  • Processing affects nutrient retention Research on silver carp shows that cooking and processing methods can change the fish's protein nutritional value and volatile compounds, which is relevant to how the ingredient performs once rendered into meal or cooked into finished pet food versus raw fish.

Also relevant

Because silver carp is an invasive species in North American waterways, some pet food brands market its use partly as a wildlife-management and sustainability angle rather than purely a nutritional one.
