could you be more specific then that? "we don't use trebles", So you say jigging the Salmon with a jig bearing a single hook, no gap wider than 1/2 inch, is perfectly legal, right?
Not perfectly legal....has to be less than 1/8 oz. and have a gap of no larger than 1/2 inch and have some kind of feather or something on it to classify it as a "fly"....regs regarding hooks pasted below.
Hooks
•Hooks attached to any lure, except an artificial fly must be free-swinging.
•Hooks may have a gap (distance between the shank and the point) of no more than one half inch.
•Use of hooks with added weight is prohibited, except that artificial flies with no more than one-eighth ounce of added weight may be used. For the purposes of this regulation, the method by which weight is added to a hook does not affect classification as an "artificial fly" provided the conditions of the definition of an "artificial fly" are otherwise met.
•Only one hook with a single hook point is permitted, except that floating lures may have multiple hooks including double and treble hooks only as permitted below.
