2) A method of poaching, possibly by digging water channels which could be dammed to trap the fish.
In 1439, tenants of Shelley were accused of illegal fishing by means of ladeyng: it was one of several similar presentments in which ‘machines’ were used, and the poachers’ method in these cases is not immediately clear. Later by-laws suggest that water channels or 'lodes' were dug, leading away from the river, which might then be dammed allowing the fish to be easily trapped: 1661-3 we lay in payne that no person ... doe ladde and cut up any mans land to dame for fishing within this liberty, Golcar
