Fish don't appear to have the ability to speak or engage in social relationship with other animals in the story, so it makes sense to eat them. Like vegan find it OK eating mushrooms even though they are closer to us than they are to plants.
Mushrooms are the fruiting bodies of fungus. Complaining about eating those is akin to complaining about eating apples; you’re not harming the tree.
For example the honey bees make honey for a reason, just as apple trees make apples for a reason and maple trees make a sugary sap for a reason. "So that humans can eat it" isn't the reason in either case. The apples and maple syrup are categorised differently by vegans because the trees aren't animals. That's still an arbitrary line, but so are most things.
For themselves. To eat. So it’s easy to understand the argument that you’re harming them directly by stealing their honey, which is the result of their labour.
But surely there’s nuance there. I don’t doubt there are ethical growers who provide bees with an extra nice and controlled environment, plus care for them and help them fight pests, and thus feel like taking a share of the produced honey is a fair trade. The bees might agree.

But it is. In the case of many fruits, the goal is for an animal (humans included) to eat them, seeds and all, then poop them out (bonus fertiliser) somewhere else.

No disagreement there, but I don’t see how any of that is relevant to my comment. I was correcting a misconception about mushrooms, not debating the nuances of vegan opinions. I don’t care for the label and don’t think it’s helpful to fight about what it means. It’s much more important to strive to be progressively better than to aim for perfection and fail.
On the other hand the bee social structure (not sure what the right word to use here) is so brutal that taking their honey seems to be just keeping pace. :)
