We cut a lot of fish. Some for eating and some for bait. In the picture at the top we are cutting a bonito into chunks by cutting in a checkerboard pattern then cutting all of those off the carcass. We will use these chunks for chumming and for baiting our hooks for a host of different species and applications.
Each fish has a way that it is best filleted or cleaned for eating. One thing that is in common with each of these is that you will need a very sharp fillet knife. As you get more involved, you can move from one knife to several which are slightly more specialized for each task. Here are some examples:
Once the fish is done you can just pull the meat off the bones and start building your tacos. Add some lime juice and bring the pulled meat back to the grill while you wait on the corn to finish. Once this is all done, you can add your street corn sauce, and build your tacos with your preferred toppings.
