Not all fish are alike, but grammatically speaking they swim similar strokes. Like salmon, tuna and the word ‘fish‘ itself, trout is the same in both its singular and plural noun forms.
This means that whether you refer to them as a singular or plural, you’re safe using trout, sans –s (sans means “without” in French).
If the word trouts with an s is used, this could be because numerous types of trouts are being mentioned (e.g., different trout species or subspecies, like a Brook trout or a Golden trout). When we refer to multiple types of things within the same group or category, its acceptable to use an s at the end (as a general rule of thumb).
