As you know there is a ton of info out there . Way more than the affiliated Wangs. There is some great stuff available the problem is sorting out all the noise. More to follow. Compensatory growth is interesting as a concept but not real applicable to supplemental feeding.
WRT BG and HBG most folks want a direct comparison but the real comparison is single sex male BG to HBG due to sex % in HBG. Studies support this comparison. See Wang # 1 above for example.
To do the BG versus HBG properly, they need to have the same father and potentially the same spawn date. Then have three or more half sibling families that are reared under very consistent conditions such as the same RAS. You can do that pretty easily using pre-made nests if you can get females to ripen on same day. It does not take much to get females to synchronize as it seems to be their natural way. Then grow out broods to point where the can be tagged and if need be females removed or at least equalized across broods. We priced out such an effort but could not find a way to fund it. Doing it in a RAS may not give same results as ponds
