I suspect that the genetics of the two species are too different for hybridizing yellow perch and walleye. IMO a "good" or high percentage of genetic compatibility of the parents has to be present for the hybrid develop successfully. Just one example - structure of the eggs of the two species are quite different. YP lay eggs embedded in a hollow gelatinous ribbon and WE scatter single eggs. Taxonomists consider these two species as belonging to different genera. To my weak genetic background of knowledge, most successful hybrids are produced from species within the same genus. Crossing a YP with a WE is like crossing a LMB and BG. Incompatibility of the YP and WE is evidenced by the difficulty during hatching and short life span of the fry. I am surprised the eggs even reach hatching stage.
