Fish in fish hatcheries are stored in concrete tanks. So as the fish swim around there find slowly wear down to stubs. A wild fish would have full fins.
The only time that I have witnessed hatchery-planted fish that had worn down fins was when they have planted brood stock. Brood stock have been kept in the hatcheries for a long time and yes their fins are worn down and also chewed off by other fish. The fish that you were referring to as "wild fish" were highly likely planters.
