Anyone have any experience with this organic compound as a lure ingredient?

Never heard of it before. Curious why the intrest in it as a lure ingredient.

Not sure of any application in lure making But you could go fishing with it:)

Anesthetic effects.
Quinaldine has been used for fish anesthesia and is more commonly used for collection of fish in tide pools and coral reefs than is tricaine. In higher concentrations, it can cause a rapid induction. Recovery characteristics are more variable than with tricaine, in part because of the relatively uncontrolled dosing that occurs with the drug in some applications. Quinaldine often does not completely stop muscle movement, and many anesthetists find it more appropriate for sedation than for induction of surgical anesthesia. Long-term sedation/anesthesia has been associated with mortality (Yanar and Kumlu, 2000). Quinaldine can be an irritant to gills and cause corneal damage, particularly when administered at high concentrations for rapid immobilization in captures or when using unbuffered stock solutions administered directly onto the fish rather than mixing the stock into the anesthesia bath water (Stoskopf, 1993).

" Four volatile chemical compounds have been identified as apparently unique constituents in urines of red foxes (both sexes) during the winter season when mating occurs. Quinaldine was found only in male fox urine. Several other compounds identified are found in other species too. Some or all of these compounds may function in olfactory communication in the red fox."

Got this quote from a canine book I bought. (To be fair to the author I won't mention the book or his name.) Just got my curiosity up about some of the commercial lures out there.

How would mentioning the book or the author be unfair to him? He wrote it and but his name on it then charged people for it.
If it was a top shelf ingredient i doubt you would get a commercial lure maker to admit to using it if they were since it's not a common know ingredient.

So it sounds like a territorial response would be the desired result if using it in a matrix lure?? Just a guess.

I guess. I have more questions than answers...

I always question the usage and attractiveness of an ingredient until I've seen multiple coyotes reaction to it. Just too many unproven thoughts and theories floating around out there to know for sure without asking the animals themselves.

Even the person that you quoted above didn't know what the animals reaction was too it or they wouldn't have used the word "may" in the last sentence.

why would you use just one component of urine, when you could more easily use the WHOLE deal?

just curious, is all...

I get close to a gallon or so of bladder urine every year... was thinking of this as additive to it to make it more attractive and louder/stronger... just a thought. I've added commercial gland lure to it for a long time, always looking for that edge.

Yes sir... anything in his book IS now available to be bought, borrowed, copied, passed on, etc. I would not get on here personally and say so and so wrote a book and said this in it... just me I guess.

Gotcha

If you want stronger pee you can set it outside in cold weather or in a freezer. skim off ice crystals as they form.

Hard to improve upon what is made organically by the body and nature. The key has always been to use it to your advantage in the right locations and to understand its value.

I know you're right Bob... always looking for that "one little thing"... you know how it is.
(My 2 main lures I use now I started using back in the 70's)

If you have some to experiment with, put out a dab in front of a trail cam. Just to see if it is an attractant.

If you collect fox urine throughout the fall and winter you will notice a distinct change in the smell, color, etc. of the urine after the first of the year. At the onset of trapping season, the young male fox have yet to mature but about Christmas time even first year fox sexually mature. Having taught high school for a few years it's about like having a classroom full of ninth grade boys! They stink! In fox, production of Quinaldine is one of the chemical changes in their urine which contributes to the smell of breeding season urine. It oxidizes very quickly and in part is what will cause even the cleanest, yellow urine to take on a brownish tint in just a matter of hours. As mentioned above it is probably more advantageous to simply use good breeding season urine than to try and soup up a formula with the chemical. Besides, I have gone down that road and it is very hard anymore to get chemical companies to sell you organic chemicals. Personally I called phooey on "in-heat urine" and "single source male urine". In-heat pheromones are so volatile you simple can't capture them. On the single source idea, there are chemical differences in the male and female urines during breeding season and I want them both represented in my lure. My preference for lure production is urine collected in January and February which I would call "in-season" urine. I believe it should also be aged at cool temperatures for several months to stabilize before building lure with it.
