70 LMB shocked up over a 13 acre lake does sound low to me.
I agree with Sunil that the results seem odd.
The "size" sampling of the fish suggest a lake full of stunted bass (as discussed above), yet the shock results come up sparse for bass.
Is it possible to have poor sampling during a shock survey? (For example, the LMB are suspended 12' down in open water?)
Is it possible to get a lake so out of balance that you have stunted (starving) fish, but no excess population? For example, all of the LMB are in one size class, and there is essentially no forage for that class, so those LMB show both exceedingly poor growth AND poor reproduction?
