Do you have better luck seining vs minnow traps?
I suck at catching minnows in my "minnow" traps. Last time out, I caught GSF and bullheads. If I did have some minnows, I figure the larger fish might have eaten them in the confined space before I ran the trap.
I am doing better at seining. My best technique now is to set the seine up in the riffles above a pool with the float line suspended in the air to the upstream side. Throw some dog food in the seine and then splash through the pool. Pick up the weighted bottom line of the seine and then I can work through everything suspended in the net at a leisurely pace.
My creek is soft sand, so I just tie each rope of my little 10' seine to the top of a stick. I can jam them in the sand and make a nice basket.
