It depends on how big the fingerling SMB are if they will eat 1" long YP. If the SMB are 2" then the majority of the 1"-2" perch should survive. Buy some FHM and they will be eaten mostly before the 1" perch. SMB that are 3" long could eat a 1"-1.25" YP. SMB of 3.5"-4" could eat quite a few of the 1"-1.5" YP.
Well fed YP from the 2013 hatch should be 2.5" to 6" long in early Sept. Those YP 2.0"-2.5" are somewhat stunted and those less than 2" were too crowded in the growing pond and had food shortages and were definitely not eating pelleted food or they would be 3"-6.5"long. 1"-2" YP in the fall will not spawn the next spring. Smallest mature YP that I've seen are 3.7"female and 3" male. Check back with the fish farm and see if they have 3"-4" or 3"-5". If so, they graded/sorted the perch and 1"-2" are mostly males and the 3"-4" are mostly females.
