Okay Lets look back to back at some things (nothing specific) on the differences between farm raised fish(freshwater) and captive pet fish....
CB
Food: Pellets Flakes Frozen
Tank: 10-300gal+
Chemicals/misc: Hydrosulfate Salts, varying Medications
FR
Food: Commercial Pellet (Trout Feed)
Tank: Alot of gallons
Chemicals/misc: Hormones, Medications
Now Unless Hydrosulfate Salts are toxic to man and not fish this is really the only difference chemically between Farm Raised and Captive Pet Fish....I've never eaten a pet fish, but have Joked about eating Pacus that are not wanted anymore....But most of the time the water in those tanks are covered in poop
