Does bleeding apply to other species or is it just a catfish thing?
Personally, I've never noticed a difference in flavor at all, but I also cut out any hint of a lateral line, in any fish I filet.
I believe your right. As long as you remove silver skin, and red meat it’s all the same. Personally, and I know this is sacrilege to some, I think is something the old timers did because they assumed it made a difference, and it just doesn’t.
For anybody who doesn’t believe me, filet a fish that still alive, and cut the filet in half as soon as you cut it off the body, and tel me if there is even a drop of blood in those filets.
