Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations 100% Green Sunfish

No I think the cross is just as viable as a BG X WM cross. It should have a skewed sex ration and F-2 are an big unknown but likely to have similar results as HBG F-2s.

Here - see this from Childers work;

Three of the seven kinds of F1 hybrids which produced large F2 populations when stocked in ponds containing either no other fishes or hybrid crappies were also stocked in ponds with largemouth bass. RG F1 hybrids and GB F1 hybrids, when stocked with largemouth bass, produced only a few Fo hybrids. No F2
hybrids were found in the pond stocked with BW F1 hybrids and largemouth bass. Only a few BW F2 hybrids were found when an 18-acre lake containing BW F1 hybrids; largemouth bass; warmouths; bluegills; channel catfish, Ictalurus punctatus ( Rafinesque); and lake chubsuckers, Erimyzon sucetta ( Lacepede), was drained. The results of these experiments, although not conclusive because of the small number of trials, do indicate that RG, GB, and BW F1 hybrids which are capable of producing large F2 populations in ponds containing either no other species or hybrid crappies are unable to do so in ponds containing largemouth bass. It is not known whether scarcities of F2 hybrids in ponds containing largemouth bass are the result of low fecundity of F1 hybrids or a high vulnerability of F2 .... The BW x B backcross was made by stocking adult male BW F1 hybrids and adult female bluegills in a pond which contained no other fishes. R x RW, W x RW, B x RW, G x RW, R x GB, and RB x W young were killed after they developed into free-swimming fry because of the lack of ponds in which they could be stocked. All six kinds of fry appeared to be normal and probably would have developed into adults. Free-swimming fry of the remaining six crosses in the laboratory were stocked in ponds and did develop into adult fishes. BW x B, G x GW, and B x RG populations produced large numbers of young.
