Not me. Our fish are pets.
Some of them even have names.
Have you seen
this family in Arizona? The quick version is they bought a house that had a big in-ground pool, but it was not in good repair, they did not want a pool AND they were worried about safety issues for their small child. So they covered it over and turned it into a food factory. Part of the cycle is tilapia, which live in what was formerly the very deep end of the pool. Tilapia will eat just about anything, so the family has the chicken pen above the tilapia pond, on top of metal grating, so all the refuse from the chickens falls down into the pool for the tilapia to eat! They get lots of plant clippings and such, which they quickly turn into fish meat.
I had quite a revelation about the mysterious tilapia. My husband kept telling me it was not a true species name, it was more a descriptive name for a type of food fish. He was right. And not only that, it turns out that tilapia are also African cichlids, which we used to keep in a big expensive fish tank and baby and fuss over with expensive fish foods and stuff. We could have been eating those little guys! I bet they would have tasted great, too, with all the babying they got.
African cichlids are interesting fish anyway, behavior wise. The females mouth brood, meaning, after their eggs are laid and fertilized, they scoop them up into their (very large) mouths and carry them around until the fry hatch. Then the fry continue to live in their mother's mouth for awhile, till they outgrow her anyway. She carries them around until she finds a food source that she believes is safe, then she spits them out and lets them eat while she patrols for danger. If she is worried about a threat, she scoops them all back into her mouth again and swims to safety.
This means that mama cichlids have to be in really great physical condition before they breed, because for several weeks, they eat little or nothing, plus they take a lot of harassment from other fish. Cichlids bred commercially are mostly males; the females are too high maintenance to raise for food, because they are such great mothers.
Fascinating creatures.
