My post should have read for 100% fertilization of all YP egg ribbons a 10:1 male to female ratio is suggested by the "experts". This ratio was likely proposed for a high YP production commercial goal. For regular sport fish growing a lower ratio of M:F will definitely result in lots of fertilized eggs. If one's goal is to have lots of larger fast growing perch for harvest which will be mostly the females, then the M:F ratio can be close to a 50:50 or even 30:70 ratio. The 30M:70F ratio should still provide plenty of fertilized eggs for the regular sport fishery.
