DIED you have pics. Look at the pic , measure that part of your finger (actual vs pic) that is visible in the pic and estimate length from the pic. Then go to the Wr table at the link below. I would guess from the pics and because they just came from the hatchery they were at 100% Wr. There is your ball park starting point.
Wr for LMB , BG and RES link (Southeast )
http://www.aces.edu/pubs/docs/A/ANR-1193/ While this starts at 6in for RES I will look tonight to see if Fisheries Tech 2d or another publication has Wr below 6in.
