Bob, Regarding recreational fish-catch counts, people that fish sportboats
are never asked because the boat and/or landing is required to provide
fish counts. Kayakers are more difficult to find, and most private boaters
are used to seeing the surveys at the launch/landing area (I believe).
And sorry, I forgot to answer your other question above regarding the
commercial guys and limits. Commercial fishermen are not regulated by
DFG "sport" limits, if any at all.
