Give me a male RTC for milking, and a gravid Tigrinus, and I will experiment on it. The only fish that get's milked will be the RTC. I doubt it if it will die by milking, but I think the male Salmon get's fillet right after milking. I don't think that the hybridazisation of the TSN and RTC were for strictly food aquaculture. I believe some fish scientists wanted to know if it can be done. I kinda like the hybrid catfish, with one exception. The flaw was the size of the mouth. It seems it does not extend as much as the TSN's or RTC. But, I'm free spirited, so anything goes...
