Steve you sure there aren�t a bunch left ? The concept is that a very high % will not live but the ones that do will grow and reproduce. You would not want all or a high % to live. For example BG reproduce at a high rate (30 to 60 thousand eggs/fry per pair of adults per year). Most of the BG fry/yoy have to die or they will overpopulate the food source (only a very small % survive to adulthood < 3 %). They either starve to death or are eaten. That is what you are trying to replicate with GShiner fry. The goal is to establish a sustainable viable population of reproducing adults. If a large % of the fry survive it is unlikely the goal will be met.
