First time I caught a totauva years ago, I was scared shitless. Didn't even want it in the boat. Tried to revive it and release it, but it inevitably went belly up. Another boat came over and grabbed it. Told them it was totuava. They laughed and said "Catch, fillet and release!" and off they went.
These days, they've come back in big numbers and some days we catch and release many, or just pull anchor and move to a different spot to get away from them.
Bottom line is: It's not us sport fishing guys that are causing the demise of the vaquita. Truly is the cartels and the gill nets. Said it before - give me three well armed large center consoles with good electronics and this shit would end. The professor is correct. There is simply no will to enforce the law, mostly due to money going into someone's pocket.
