All catch and release. I might be back there this year with my own gear (I borrowed gear from someone when I was there for an hour). In which case I will be soaking my line in every body of water I see. Might try to bring a little something home then...
Rob, make sure to fish at the Parismina river, that's where I caught the nice male I brought back. I also caught maculicauda, loiselle and a whole bunch of silver snooks.
