Never keep them but should I???

Yes you should there is a good market for them. Save them fresh frozen so the end user can do what they want with them.
I have had good results using it fresh preserved in homebrew lures. Next year I want to rot some down. Also saving the belly & throat glands this year for my next homebrew batches.

Ever see what a dog does at an otter toilet? They wont pass it up.

I'll make sure to hold on to them from now on.

I would save them

Ever see what a coyote, fox, or a bcat does at an otter toilet? Rot the glands down to a paste and use the lure as a changeup at your predator sets. You wont be sorry.

Idk about the glands but I tell ya nothing eats an otter. I throw all my carcasses behind my house in the woods for the critters and birds.. those otter basically rot down or get eaten by maggots. Nothing else touches them, not even the buzzards. I've always wondered why.

Yep

I threw otter carcass’s on field and In one day the ravens , crows and eagles had them stripped clean right to the bare bones.

That’s odd, here they’re the last thing they’ll touch in a carcass pile in fact they usually lay there and mummify. The glands good though.

One day I threw out a 40 lbs and 25 lbs coyote carcass a 25 lbs and 12 lbs coon carcass and 2 otter carcass and 2 days later they were completely cleaned. Ravens are the most numerous. I think they keep the crows away then bald eagles and this year golden eagles. I am blown away how much meat these birds eat and how fast they do it. They clean the skulls almost totally making it easy to save a skull.

Otter get eaten here-sometimes right out of the trap.
Lynx and wolves(wolves eat everything) love eating them.

Boco
Up their in the cold and snow ur critters can't be too picky. They would probably eat a dead vulture in they winter if one was available

I use the glands in a predator lure, really add to the other smells.

Even the birds avoid them here ! Local Wolf population would never stoop so low as to eat an Otter. No matter how cold it got !

I dont think otter gland attracts coyotes and bobcats as a food smell. They both like it and will walk over for a sniff. Pine marten like that smell too.

Here is a nice big otter that was pulled out of the water last fall and eaten by a family of lynx



Just another package of protein in the North country.
