in a nutshell, he is talking about the diferent types of fishing in that region in Brasil at the end of the video. He talks about the wild things that happen on the river at night The beginning is funny cause he is basically saying lets go see what we can come up with tonight! during the madness its hard to translate, but he is basically saying holy crap look at this it's beautiful. i watched fishin shows every sunday morning when i lived there- went off the surf a few times. the fishiermen love to say "olha so"- look at that -always reminded me of Roland Martin's "son"!
