No, bones in that fillet after stomach gets trimed out. Guts went one way and all fish heads and bones went another.. everything but guts will be used for something
eh? He just zipped that knife from tail to head....holding it flat....where'd the rib bones go? Gutting it first didn't remove them.
I have never cleaned Mahi.....but lord knows I have filleted a bazillion walleye and yellow perch in my life. If you just hold your knife flat and run it from tail to head like that all the ribs are still in the fillet.
With a regular fillet knife you can work your knife around the ribs and leave them attached to the carcass. Then you can skin it and have a comepletely skinless boneless fillet.
We now use electric fillet knives a lot on walleyes and do it much the same way as in this video. Once the fillet is off the fish we then remove the ribcage.
Maybe there was another worker we couldnt see who was doing this step.....removing ribs and skin
