Go get some yellowtail either with a fishing rod or pole; they taste better than farm-raised (think wild salmon vs farmed salmon). Smaller Yellowtail take a day to two to go through rigormortis and tenderize naturally. Larger yellowtail, depending on the manner they were harvested will more than likely be 3-4 days before they are ready (the muscle fibers will still be tight). You’re going to have to taste the fish in that time frame to make sure it’s perfect for serving.
