What is the plural of Fish?
Do you say fish or fishes?
The plural of fish is almost always …. fish. (No -es at the end)
- 1 fish
- 2 fish (NOT 2 fish
Some example sentences:
- I caught three fish yesterday down at the wharf. (caught is the past tense of catch)
- I bought some fish for my aquarium. (bought is the past tense of buy)
There is even a famous book by Dr. Seuss called One fish, two fish, red fish, blue fish. Note how it is two fish and not two fishes.
When can I use fishes?
Fish is used when we are counting individual fish …. one fish, two fish, three fish… etc.
A number of fish of the same species are called ‘fish.’
However in marine biology / zoology etc., ‘fishes‘ refers to more than one species of fish.
We are talking about entire species and NOT individual fish numbers.
- I read a book about the freshwater fishes of New Zealand.
This book talks about the different species of freshwater fish in New Zealand. We use fishes because there is more than one species. We are not counting the number of fish, just the amount of species.
Fish or Fishes?
Imagine you have an small aquarium. In that aquarium there are 6 fish. This means there are total of 6 individual fish. They may be of different types but we are interested in the number of fish and not how many species there are.
If I say there are 6 fishes in my aquarium, it refers to 6 different species of fish. There might by a goldfish, a clownfish and four others including a piranha (ok, maybe not a piranha as it would each the other fish).
However in general everyday English, we would most likely say:
- There are 6 types of fish in my aquarium OR
- There are 6 species of fish in my aquarium.
Also, if you have a bucket of fish. There may be more than one type or species of fish in it though you will normally say:
- I have a bucket of fish. (not fishes)
