Here is one I did when I lived in Ft Lauderdale in mid 70's. Took a old cheap dip net with the green plastic mesh, then bought a curtain shear ( ask your wife ) sewed it into the shape of the net then laced it around the hoop and used fishing line and upholstery needle to tack bottom to bottom of net. Then just run it up under Hyasinth pods lift and shake. Usually get enough in one or two try's to fish for awhile. If you run out just ease back in and get some more.
