Bit of a funny one Flathead, if you fillet, skin and debone, there's bugger all left, even off a decent Flathead, I fish for Sand Flathead (Blue Spot) now and then, and catching my bag of 10 is pretty easy, but when prepared, I would eat 3-4 fillets myself (2 fish) my wife maybe 2 fillets, kids a couple each, then add the grandkids (we usually have a "fish night") it doesn't take long for 10 Flatties to disappear, I usually only keep the bigger ones and between us, we get 20 fish, that leaves only a few fillets for the fridge or freezer. Kingfish are a different story, you get a fair return of flesh when filleted, boned, skinned and all the blood meat cut off, but, it still takes a decent one, or a couple of "just legal" for our family fish meal. Size and bag limits have been debated, digested, spat out and argued about countless times, and there is no clear winner, the average Joe who fishes once a month and might catch a few fish, V the "full time" fishers (like most of us) who fish regularly all have a very different view on sizes and bag/boat limits.
