According to the definition posted above, the cultural expressions of biological sex are only one dimension of gender, and you’re ignoring the other aspects. I’ll accept fish don’t have culture, though I bet someone more knowledgeable than I could argue that point. However, let’s look at social behavior via a vis courtship rituals. Like birds, some fish develop pretty incredible displays for getting it on. If a fish which has changed its biological sex then changes it’s behavior during courtship, that would seem, to me, to indicate a different expression of biological sex independent of genetics (i.e. gender). Unless there is a genealogical basis for courtship displays, which I don’t believe to be the case.
You can argue along those lines but then you’re ultimately arguing against the sex-gender distinction. If you read the full Wikipedia article on gender posted above essentially none of it applies to fish whose behaviour is entirely biological and environmental. We know this because you can substitute any fish in any role for another of the same species and see entirely predictable results.
