In this paper R refers to red-ear sunfish, B to bluegill, G to green sunfish, and W to warmouth.

4.1 Sex Ratios of F1 hybrids
Sexually mature F1 hybrids were collected from each population and sexed. Of the 10 kinds of viable F1 hybrids, seven were predominately males (RB, BR, and BG were 97 percent males; WG were 84 percent males; and RG, GB, and BW were approximately 70 percent males), two were approximately 50 percent males (GR and RW), and one was predominately female (GW was 16 percent males). Ricker (1948) determined the sex of 428 BR F1 hybrids in Indiana and found them to be 97.7 percent males.




Small ( 8 inch) plastic or clay saucers that go under potted plants filled with small gravel will work well.


Excuse my ignorance, but what's the difference btw RB and BR? One is F RES and M BG and other is inverse? If so, anyone have experience with M RES and F BG hybrid? What are differences btw it and our standard hybrid F RES M BG? An ice cold diet pepsi at the conference for anyone who cares to enlighten me.
