The American plaice or sole, Hippoglossoides platessoides, is a flatfish that belongs, along with other right-eyed flounders, to the Pleuronectidae family. American plaice are an Atlantic species.[1] Their range is from southern Labrador to Rhode Island. They spawn in the Gulf of Maine, with peak activity in April and May. They grow to a maximum length of 70 centimetres (28 in).[2] The species is considered by the Northwest Atlantic Fisheries Organization to be overfished, with no signs of recovery.[3] On the other hand, the Canadian government believes the species is abundant, and counts it as the second most caught flatfish, totalling 50% of the flatfish caught by Canadian fishermen.[4] A 1997 study reports that plaice are endangered in Canada due to overfishing.[5]

American plaice may be an intermediate host for the nematode parasite Otostrongylus circumlitis, which is a lungworm of seals, primarily affecting animals less than 1 yr of age.
