No doubt CM. We found out seining that you had to keep the bow in the seine parallel to the current our the fish became packed in the bow and not good. Also hand pulling really sucked so it was block and tackle with a tow vehicle but you had to be very careful not to bring it in and jam the bow. Then if that was not enough that was the easy part. Sorting without harming the fish is not easy as you have literally dip net the fish in the water to avoid damage. Then the last thing was it takes about a 4 person crew to operate the seine safely bank based and if using a boat for a tug cost, man power, and risk of injury for the fish and people go way up. It can be a bitch especially if your effort involves mixed species and the number captured is substantial.

Tried traps twice and if the cost and effort did not chase one off all you had to do was wait for a rain. If the current didn't try to wash you away ( which it will ) then the mass of crap from sticks, logs, and everyone's favorite ......... grass. On a rise things coming down stream leaves, algae, just everything nature has laying around the stream turns a trap into a giant garbage catcher. One of the guys said that his wife said it had one benefit, it took care of his desire to man the trap at night.
