Don't use that pressed stuff sold on amazon. If you want fish oil get some good catfish or trout or spoonbill.

Blackies blend “thumbs up” is a fresh fish bait preserved.
That’s the one I was thinking of previously. Really good coyote bait change up from other meat based baits.

Got friend that does well on predators using nothing but small bluegills pinned down under his trap pan.

My Grandpa caught 100 plus red fox many seasons using chunked sheepshead. It was a blast catching a few barrels full.

Chunked carp was one of my go to change ups for coyote bait. Free for me, fun to catch in summer.
I had watched plenty of the far north folks feeding their dogs salmon or using salted or dried salmon at sets for a wide variety of animals it got my attention.
Late season set I use a lot is in flat picked bean fields I kick a pile of bean chaff into a pile, bed the trap on one side and on that same side stick a chunk of carp back under the chaff pile.
I think I added them to my coyote bucket when I started catching coyotes at my coon dirtholes baited with carp. A few catches at first sort of like a fluke. After several more catches it seemed to be something I needed to pay attention to.

Jamesons has a good trout fish bait and a chunked bait. I’ve even had good luck with koi fish cleaned and chopped in half with some trout oil around it.
