Pantoja is the expert here as he used take rays in Cuba. He explained that once the ray is weakened you have to approach carefully, grab the tail and with the other hand swipe the knife across the tail removing the barb. You can see him sort of trying to do that in the vid but then he realized that the ray was already missing the barb. We don't know how it lost the barb, whether it was during the fight or previously.
The ray was incredibly strong and there was no stopping it. It pulled and pulled for about half an hour. We put four shafts in it and it only had the effect of anchoring the lines to the fish. Eventually when it tired out you can see that Pantoja jabbed it a few times in the head which I think weakened it further, although it gave one more thrashing just before raising it onto the boat. On the boat it was more precisely stabbed in the head a couple of time more which finally dispatched it.
