Catfish are fed hormones in farms, especially in the Asian countries where they are bred. If you can find free-grown catfish, that should be selected over imported catfish.
How to Choose Good Fish
Fresh fish vs. spoiled fish
Fresh fish have clear eyes, shiny scales, bright red fins and gills, and a tail that is not low. Spoiled fish have clouded eyes, gray fins and its gills and tail hang weakly.
Live fish in a tank that is closer to the surface and is in clear water are better than the one which is not in clear water and closer to the bottom of the tank.
If you catch live fish and cook it, check the level of mercury in the water from where you’re catching the fish.
Choose salmon steaks that have white marks. If the steak is excessively red, chances are that they have been dyed. Don’t choose fish with white spots on the skin as it indicates they have been caught in the spawning season, and so, it will not taste good.
