Capitalisation of fish names depends on the context.
If you are talking about the name of a specific fish, for example a pet fish, you would capitalise (eg. "Bob" my goldfish)
If you are using the common name of a type of fish in a sentence, you do not need to capitalise (eg. I ate salmon/trout/sardines last night) unless it is the start of a sentence.
If you are using the scientific name, you capitalise the genus name but not the species name (eg. Salmo salar)
It depends on the context. In general, common fish names are not capitalized unless they include proper nouns or adjectives. For example, "salmon" is typically not capitalized, but "Atlantic salmon" would be capitalized because "Atlantic" is a proper adjective.

Capitalize days of the week, months, and holidays. Capitalize the titles of books, movies, and songs. Capitalize the first, last, and important words in titles.
