Oysters are shellfish. They barely qualify as animals, seeing as they don't move, but they're animals nonetheless. They make pearls, but they also make good eating.
Shrimp are also edible ocean animals--small, so you have to eat several of them at once to get a meal.
Supply and demand and what the rest of the market has tends to change things, but I'm an independent fisherman, so I set my own prices.
I do not have a commanding officer. There's relatively little in the way of military here at all. What there is, it's really more like a militia than the standing army of a nation.
I have eaten my own fish. There's no requirement to turn them over to anyone. I sell a lot more than I eat.
Old Asgard was destroyed, or maybe carries on in another world. I've never been very clear on which one the locals think takes precedence.
