Plural of “salmon”

The plural of salmon is salmon.

Why

"Salmon" is one of English's zero-plural nouns — words that use the identical form for both singular and plural — a pattern especially common among fish and game animals traditionally hunted or caught in groups, where individual members of a catch weren't linguistically distinguished from the catch as a whole. "Salmon" comes from Old French "saumon," ultimately from Latin "salmo," but the zero-plural behavior is an English development, not something inherited from Latin or French, both of which pluralize their own words for the fish regularly.

Linguists generally trace this pattern to how fishing and hunting communities historically talked about their catch — "we caught salmon" describes an undifferentiated haul the same way "we caught fish" does, and this collective, uncountable-feeling usage seems to have blocked the ordinary plural -s from ever taking hold for many fish and game words, even though grammatically these are still countable nouns (you can say "three salmon," not "three salmons").

Usage note

"Salmon" stays unchanged in every ordinary counting context: one salmon, three salmon, dozens of salmon migrating upstream. The rare form "salmons" appears only in specialized biological writing distinguishing multiple species of salmon (Atlantic salmon, Chinook, coho, and so on, treated as distinct "salmons" collectively) — a specialized, minority usage most readers will never need.

Because "salmon" doesn't change form, verb agreement depends entirely on context and number words rather than on the noun itself: "the salmon is swimming upstream" versus "the salmon are swimming upstream" — both grammatically correct, distinguished only by whether one fish or many is meant. Some regional and historical usages did use "salmons" more casually, particularly in older English texts and in translations of foreign fishing terminology, but modern standard usage has settled firmly on the unchanged zero-plural form for ordinary counting, reserving any -s form for the narrow species-comparison sense described above.

Common real mistakes

Adding a plain -s ("salmons") to describe multiple fish of the same kind is considered nonstandard outside the specialized species-comparison usage described above; for everyday writing about catching, cooking, or observing salmon, the unchanged form always covers both singular and plural.

The wider pattern

"Salmon" belongs to English's zero-plural class alongside "trout," "deer," "sheep," "moose," and "fish" itself in most contexts — a pattern most heavily represented among animals traditionally caught or hunted in undifferentiated numbers, rather than a broader grammatical rule applying to nouns in general. The distinction between wild and farmed salmon has become an increasingly prominent topic in food and environmental writing, with farmed salmon now vastly outnumbering wild-caught salmon in most markets worldwide, a shift that has changed both the ecology of salmon fisheries and the vocabulary used to describe them, though the plural itself has stayed constant throughout.
