Yes GSH and other small fish will eat the yellow perch fry until the fry get too big to fit into the mouth of the predator. However depending on the number of fry, number of shiners, and amount of cover all will govern the survival rate of the YP fry. A large number of adult shiners could easily and significantly reduce the recruitment of YP. This is the situation of Dono from Ontario who has lots of shiners (common and emerald) and his YP recruitment is quite low. I have common numbers of spotfin shiners and I have good recruitment of YP.
