I would rather eat catfish than Tlapia...
and I hate catfish.
Now striped bass, or young shark are fine eating
and smoked Cobia is to die for.
Tlapia is just muush.
*** “Tlapia is just muush” ***
You are overcooking it ... we catch Tilapia all the time, they are unwanted at the Lake, no Limits...
Good table fare (much better than Catfish) texture is similar to Bluegill or Crappie, they have a very mild flavor and not at all tasteless also they actually freeze better than Crappie... which is necessary for the large amounts of Tilapia that you can catch with a cast net.
I suggest that you bread them lightly (Cornstarch and Cornmeal) High Heat just a light brown on each side and they are done.
I have also used them in stews, add the fillets or chunks a little after small shrimp and they will be done at the same time, they cook quick.
They Bake fast too ... I do the press method on the smallest one in the pan.
