About Red Bigeye

Red Bigeye is a marine fish (Priacanthus macracanthus) processed into meal or flaked protein for dog and cat food formulas.

Red bigeye is used as a fish-based protein and flavor ingredient in dog and cat foods, providing high-quality animal protein, essential amino acids and beneficial omega-3 fatty acids that support skin, coat and overall health. Considerations include the potential for food allergies in some animals, variability in nutrient levels (including taurine), and possible contaminants or thiaminase activity in raw fish—risks that reputable manufacturers address through processing, testing and balanced formulation.

Why it's used

Red Bigeye is a coastal, bottom-dwelling species in the Priacanthidae family that is commercially caught in Western Pacific fisheries and processed into meal or flaked protein for pet food, making it a regionally available protein and fat source. As a fish protein it supplies amino acids and marine fatty acids alongside the flavor profile that many cats and dogs find palatable.

Common concerns

  • Distinct from bigeye tuna Red Bigeye (Priacanthus macracanthus) is a smaller fish that feeds lower on the food web, biologically distinct from bigeye tuna (Thunnus obesus), which is the species that appears on mercury advisory lists; the two are commonly confused because of the shared common name.
  • Fish protein allergenicity Fish as a protein category is one of the more commonly reported food allergens in dogs and cats in veterinary allergy literature.
  • Thiamine breakdown in raw fish Some fish species contain thiaminase, an enzyme that can break down vitamin B1 if fed raw and in quantity, though normal cooking and rendering used in commercial pet food processing deactivates this enzyme.

Also relevant

Cats fed diets built heavily around fish need the formula to supply adequate taurine, since taurine deficiency in cats is a documented cause of dilated cardiomyopathy.
