AJ's has them.. but it's a shame as he had priced the small smelt and then priced his "large" smelt at $8.00/dozen. Well.. past couple weeks he's only had the one size (small) yet still $8.00. Too bad cause that was my go-to place as his large ones were healthy and durable ..well, as far as smelt go at least. I got two dozen of the small ones last weekend, still $8.00... and all but two died in an hour. Same bait bucket, aerator etc. I always use with no problem. disappointing and frustrating for sure.
Also... there are many possible reasons why your Smelt did die in your bucket... without knowing how you transport, handle, bacteria growth within your bucket, chemicals, etc. I can't help you and obviously without notifying me of the mortality there would be no solution for your issues.
