Thanks Eric - I had not encountered anything RE the RB hybrids as everything I'd read on the forum thus far had been dedicated to BR hybrids. Of course it makes sense this cross can happen, I was just never exposed to it. I wonder if the RB and BR hybrid express any different traits? From a reproduction standpoint apparently there is no difference [97% males] - but that also leaves me with another question:
According to what I've read - female BG lay significantly more eggs than RES. Female BG are also willing to spawn multiple times/year whereas RES apparently spawn 1x annually, at least in our Northern bows. Combine these two elements and could one expect that RB hybrids would far outnumber BR hybrids in a one year pond by experiment? If one is trying to raise RB/BR hybrids, the RB would be a more attractive choice due to sheer QTY of offspring. Any thoughts?
