As posted the last time this thread came up:
What I used to do was grind salmon eggs, herring, salmon (after filleting), ect thru a course grinder- then inserting that into 4 oz juice bottles (ones that have same lid as soda pop. Then freeze them. meanwhile, save up a few extra lids and drill a hole in the center and place a small eye bolt with washers in them. Keeps thing nice and clean, and you throw away the used ones in the trash at the dock. Put the unused, uncut ones back in the freezer. save the eye bolt lids for multiple use later.
When you get to where you want to fish: cut slots, holes, chunks, whatever out of a bait jar; screw on a eye bolt lid; attach on to your fishing line above the bait.
Had one "something" grab hold of the bait jar onct, and was a very short fight (no hook). when got it up jar was completly smashed flat with lots of scratches on it. Who knows what tried to feed on it.
Since been fishing with Capt Dennis on the "Otter Dodger" haven't used anything in a while. He has the "local knowledge" to get our fish without using chum. (except for the occasional over-the-side chumming us anglers do from time to time
