heres an idea, that someone posted and worked great for them.
if you have a large rock structure in the middle, cut 2 pieces of egg crating so it fits around the rock in the front of it, and behind it. then they raised the crating, and took another piece vertically, and swept it across while liftinf the crating up from the bottom.that way they contained the fish in a small area, and was able to net them very easily.
it seems not too bad, but box trap IF WORKS, would definately be the easiest.
