How many hooks? (I don't think there is a legal limit(?)
Legal limit is 5 hooks per line. See current fishing regs page 47:
Hook: A bent wire device, for the catching of fish, to which
one, two, or three points may be attached to a single shank.
Up to five (5) hooks per line may be used, except where
specifically prohibited. When fishing for salmon or steelhead,
the gap between the point and shank cannot be greater than 5/8
inch. A single-pointed hook has one shank and one point.
