If you choose to filet a Blue Marlin, experts recommend that you use a very sharp knife. To begin, cut the bottom fins and peck all the way around. After that, place the blade near to the fish’s gill and slice to cut off the head and intestines.

Then, from the tail, you’ll want to create an incision to spin. The remainder of the procedure is quite similar to that of fileting a bigger fish such as a tuna. The nether regions of the fish should be cut into thick filets on either side.

To optimize the flesh in the filets, penetrate deeply along the Blue Marlin’s flank directly down to the tail. To keep the filets fresh, freeze them as soon as possible after cutting.
