Ok here is the question. If I have TONS of shiners just swimming all over my pond could I use them for scenting purposes only or is the thiaminase risk too great. I don't plan on letting the garter ingest the fish i just wanted to rub the shiner on some pinkie parts. I have plenty of crappy available too, I just have to hook it first. the shiners I just dip a net in the water and I get one. i don't want to risk the health of the garter I don't even have yet...just investigating the nonmouse renewable food sources I have.
