from Pg. 4 of the synopsis
Single Hook: it is prohibited to angle with
a hook with more than one point on waters
that are subject to a single hook regulation.
Single hook regulations may be in place
year round or seasonally. Where single hook
regulations are in place on a water body it
applies to angling for all species. Often single
hook regulations are combined with barbless
hook regulations and termed “single barbless
hook”.
Barbless Hook: it is prohibited to use a hook
with a barb on waters subject to a barbless
hook regulation. Barbless hook regulations
may be in place year-round or seasonally.
Where barbless hook regulations are in place
on a water body, it applies to angling for all
species. Often barbless hook regulations are
combined with single hook regulations and
termed “single barbless hook”.
What you are asking about is, is a stinger hook (the trailing hook on a bucktail) prohibited under these regulations. I don't know though I have always thought so.
