rou
1. (noun) dredge (for shellfish).
I tēnei wāhi ka tukua te rou ki raro, otirā kāore he mea tikanga i riro ake, he mea kōkota noa nei, ehara i te mea āhua hou (TWMNT 14/7/1874:172). / At this point the dredge was lowered, but nothing of any importance was brought up, only some pipi but nothing new.
