Before touching the package, make sure to sniff catfish. Fresh catfish will be mildly scented with clean smell like a cool pond or ocean. A little earthy isn’t bad, but it shouldn’t smell like ammonia or being pungent in any way.
The sharp smell indicate bacterial breakdown of flesh. You’ll want to set it back down if just the aroma makes your nose wrinkle. Seasoning and lemon juice won’t save dead meat.
How to Identify Fresh Catfish Fillets
Check the Smell for Freshness
Examine the flesh. Good catfish fillet will have some translucence and a bit of sheen to them. They should be creamy ivory or pure white in color.
Any gray spotting or pinkish tints mean that fish is on its way out. The flesh should also being dense and firm. It shouldn’t slide around in whatever package it’s in, nor it should be mushy.
Inspect Color and Texture
Fresh fish are firm. Also note what it look like in pack. The fillets shouldn’t have much, if any, free liquid pooled on the bottom.
Some normal clear moisture is expected as fish cells naturaly give up some water. But yellowish/milky colored liquid mean it’s swimming in a pool of bacterial byproducts and broken down cell fluids. This mean the fish has been sitting around too long or was handled poorly.
Examine Liquid in Package
Better dry then wet. If you know where the fish came from, consider that to. Clean, well-filtered tanks generally produces cleaner tasting catfish different than muddy pond-raised catfish.
Farmed catfish is more consistent in flavor, whereas wild catfish can range widely based off their diet. Seek out products from companies that are open regarding there production methods. Companies who care about water quality will spends money on it, and that shows up directy on your plate.
Consider Source and Farming
Last but not least, examine the package itself, look at packaging condition and the expiration date. Dented containers will let air in, which bring in bacteria. Spoilage is accelerated by air, so if the package is broken or swollen, toss it.
Check Packaging and Expiration
When possible, shop at stores with a high turnover rate in their seafood department. If it’s busy, then it mean they are moving product, which means it’s fresh. You don’t want the fish that’s been sitting in freezer for weeks, you want the one that was just unpacked.
So now you’re buying fresh catfish. It doesn’t has to be a guessing game. Trust your senses.
A good fillet will come from a reputable source, have minimal liquid around it, smell clean, look white and firm and will be separated from the rest of catch. The difference shows when you take a moment to carefully inspect the package at the store. That tender, sweet bite is well-worth the few moments it takes you to check out fish.
