About Plaice
Plaice is a mild-tasting marine flatfish (Pleuronectes platessa) added to pet foods mainly as a lean animal protein and flavor source.
Plaice is a lean white flatfish used in pet foods primarily as a digestible, high‑quality protein and palatability ingredient that also supplies modest amounts of marine omega‑3 fatty acids, supporting skin, coat and joint health. It is generally lower in heavy metals than large predatory fish but should be properly processed to remove parasites, can be a food allergen for some pets, and diets relying heavily on fish must be balanced to avoid nutrient shortfalls (e.g., taurine or thiamine) and to ensure sustainable sourcing when possible.
- Derived from
- European plaice, a flatfish species
- Primary role
- lean animal protein, palatant
Why it's used
Plaice is naturally low in fat with a mild flavor that many dogs and cats find palatable, and it is one of Europe's most heavily landed flatfish species, giving manufacturers a well-established supply chain. Its muscle tissue delivers a complete amino acid profile typical of white fish, along with modest iodine and B-vitamin content.
Common concerns
- Thiamine breakdown when fed raw Raw fish, including flatfish species, can contain thiaminase enzymes that degrade thiamine, a mechanism the Merck Veterinary Manual links to thiamine deficiency in cats fed raw fish-heavy diets over time.
- Fish allergen status Fish is one of the more commonly reported food allergens in dogs and cats, so plaice-containing formulas are generally avoided for pets with a diagnosed fish sensitivity.
- Environmental contaminants As a bottom-dwelling marine species, plaice can carry trace heavy metals or persistent pollutants depending on catch location, though as a smaller, lower-trophic fish it is generally considered lower risk than large predatory species.
Also relevant
Plaice is typically cooked and processed before inclusion in commercial pet food, which addresses the raw-fish thiaminase concern noted above.
