the way I read it 4 hooks, I don't see any other way of looking at it
Hook – A hook includes a single-pointed or multiple-pointed hook on
a common shaft but does not include a snagger or spring gaff. The
number of hooks includes any single-pointed or multiple-pointed
hooks that are part of a lure.
Hooks and Lines – An angler may use only one line, unless
otherwise stated in the regulations. Two lines may be used when
angling from a boat in parts of the Great Lakes (see Exceptions
to the General Regulations) and for ice fishing in many areas
(see Ice Fishing, page 11). A fishing line must not have more
than four hooks attached.
