Both very interesting Jim.
Surprising to me that the RES grew faster than the BG.
The RES and BG were ran in same culture system but different trials. Additionally, both species where each represented by a single full-sibling brood. Either of those factors make comparisons between species based on that publication weak at best. Subsequent trials where both species were represented by co-mingled broods are consistent with RES have more rapid growth indoors in tanks fed diets formulated for trout. In pond settings, results not as consistent. RES in ponds are less consistent feeders under conditions most people have.
