Usally get a gallon every season an use glycerine if needed for antifreeze, I was reading a coon trapping book, long ago where austin passamonte , was using vegetable oil with a lil shellfish added, said it was as good as salmon oil, smell vegetable oil. Smells quite simlar, was looking for some feedback on this

I don't know how salmon oil tastes, but due to a very unpleasant day, I do know that shellfish oil tastes horrible. I don't think I would use it where a coon could taste it.

Well maybe vegetable oil with glycerine if cold an shellfish be better , the fish oils gel above 32 salmon oil, not quite as bad as straight fish oil

Ttt

Garold Weiland of Longliner fame used to sell a shellfish lure, of which I still have some bottles of it. It has it's own unique odor as you know it is not fishy. It is strong though and Mr. Passamonte was quite genius in figuring out how to make tincture or emulsion of cheap bulk oil with a more expensive product. There is chemistry involved in this in long chains and how things bind, as oil and water do not mix, no more than petro oil and veg oil do not mix, although they do not separate out. The short of this is providing your vegetable oil, which was probably corn oil, which had very little scent when it was fresh, would be a wonderfully cheap substitute to extend shellfish. Raccoons will eat about anything that is food, so maybe a stronger odor of olive oil might work, but at 28 bucks a gallon, that defeats the purpose of a light vegetable oil.
The main obvious point would be if canola or rape seed oil which does have an odor, could be overpowered by the shellfish, that the target animal would trigger to an easy meal. Then like corn oil, you would have a perfect extender for a 3 to 5 dollar an ounce bottle of lure.

As the coons are not going to be tasting it or eating it, the veg shellfish would work ideally for something Carroll Black used to do, in he kept fish oil in a squirt bottle and said he would make a set in a good location away from the water's edge, and squirt a trail of lure to his set. For the young trappers or the older ones who have never considered it, in this method you can squirt a line across gravel road if you see coon tracks, and they will follow it to a culvert, bushes or brush in a set where no one can see.

To put your post where my words are, I will be using your Passamonte idea with Black's this year, as cheap good lure is what dealing with lots of cheap fur raccoons is all about.

Thanks for asking that question in sharing that old information, as this genius takes too long for others to figure it out again. It is a great teaching point on Trapperman.

I think you could use whatever you want as an extender as long as it isnt a deterrent. Your are basically just diluting the potency of your lure by adding another compound. You cant expect to mix a gallon of salmon oil with a gallon of vegetable oil and end up with 2 gallons of the original salmon oil, but you will have 2 gallons of oil that has some characteristics of the salmon oil. It wont smell the same, it wont be as "strong", so it could be that it wont be as detectable, or at least not as detectable from the same distance.

Adding a compound could cause the lure to go rancid over time, so it may be better to mix what you need for a certain time period, rather than make a large batch and try to save what you dont use.

I would worry most about the fish oil going rancid. I try to use my fish oil up before it goes bad.

Sun rendered fish oil should never go bad or rancid. I have had some private stock pure Trout oil for over 47 years that is as good as the day I drew it off the batch of working fish. I would imagine any clean oil would hold fast in odor if in a good container. Much like good urine. It will hold forever in the right conditions as long as the material was handled well and was relatively clean prior to containment.

Sun rendered is good but awful bad smell if get hands, strong, mazola corn oil smells good. Does it taste good to coon? So I buy fish or salmon oil, how do u know, how much it is cut with filler?

You haven't had pure trout oil it doesn't stink as you say. It is a sweet fishy odor that you wont forget. Not bad as you think or maybe you don't know the smell. Lasts a long time and very appealing. You may be referring to fish juice which many think is fish oil. You can cut good pure top run fish oil with mineral oil very nicely to extend it.

Can always grab used fry oil from a restaurant or the local county/state fair for free. Add whatever smells you wish and be as liberal as you wish with the low cost. Alittle Glycerine helps in many ways.

I've kind of went that route as I found most fish oils don't smell very fishy...or much odor at all. The add ins far outsmell the fish odor. I give the fish oil to my dogs now. Great for their coats and allergies.

That said, I do have some of Bob Jameson's Trout oil. This is the first fish oil that I've used that really smells like something. Enough so, I wouldn't hesitate to use this alone as a lure/attractant. And you wouldn't need much.... As stated, it doesn't "stink". It smells fishy and sweet. Kind of like if you ever cut up fresh spring spawning suckers. That's the one fish I found that has a really pleasant and alluring odor that out produces other fish. Just my observations...right or wrong.

Blue Ridge Outdoor Supplies, Elkton,Va sells a fishy smelling menhaden fish oil. I love that stuff, I like to use it straight.
