LR64,
This site may help you identify crafish from your area. NY may have some crayfish species not reported from PA. The crayfish that you are collecting are probably common species and will likely be in the PA identification key.
http://www.lhup.edu/tnuttall/crayfish%20figures.htm Keep in mind that since you are putting in SMB in the 6"-12 range you will need to stock larger sized perch (4"-8")to improve the perch survival rate. Most of the 2"-4" perch that you stock initially will be bass food. A first perch spawn will provide enough young perch to allow for predation and thinning of the first perch year class.
