My guesses:
green x longear
p-seed x longear
bluegill x longear

Hmmm... these are tough. How about:
1) Bluegill x Redbreast
2 and 3) Bluegill x Redear x Pumpkinseed

JIM, why would one do this?can they get out of there aquaculture area?Gerald,
You may have cheated.
The answer for first fish is allotriploid 2/3 bluegill + 1/3 redbreast. Bluegill egg fertilized by redbreast sperm with resulting zygote pressure shocked two minutes post-fertilization (ploidy not verified but previous efforts give 100% triploid). The redbreast characteristics are more apparent than I thought they should be.
The latter two fish are a trihybrid that is 1/4 redear + 1/4 pumpkinseed + 2/4 northern bluegill. A female redear was crossed with male pumpkinseed yeilding a fertile F1 hybrid. A female F1 hybrid was then mated to a northern bluegill male. Morphologically, young clearly show bluegill and pumpkinseed inputs but redear not obvious. Fish also extremely variable.

A while back we did a cool experiment where we put bright red earings on the male bluegill's opercular tabs. They did not stay on long but while they did the wearer enjoyed the ability to drive rivals off their nest.

One word: WHY?

This hybridization experimentation is awesome, i hope to see more amazing crosses soon.
Also earings for fish sounds interesting, the first i heard of fish fashion.
Did the earrings effect the bluegills mating success any? did the females react as if they were a different species?
Also what hybrids are the easiest to make? will any of the species hybridize very very readilly?

I think the coolest hybrid will be the Warbuck (Warmouth x dollar) I had some hatch but failed to achieve exodus with the cross, although only a small number was produced at maybe 100 and only 12 hatched...The coolest cross to be made yet will involve the longear from the lower Mobile River drainage with western dollar and redbreast. Student doing this to look a variation in larval morphology as a function of cross direction (who is the mother).

So what post-zygotic barrier(s) do you think you encounter with the Warbuck cross?
