yup, its secured to the net with 4 plastic ties, your right about keeping busy, I tend to place them around 8ft apart along the sretch of river, luckerly it has a footpath alongside so its easier to move along, then starting at the first, lift them one at a time every 90 seconds or so, probably after the 2nd or 3rd lift, all nets get slowly moved up one place, so we gradularly move upstream,
