Leave it to an observent type, sorry Steve, I changed up my jars this year and no longer use the holie jug thing.
To begin with I had the poly jugs drilled nicely and they worked fine but mine were tall enough to fill the bait well and held a ton (too much) bait. It was easy enough to use less bait but I also like to add fish scraps and the tall jar left no room.
Solution: While aimlessly wandering the isles at B/J Commercial this spring I stumbled onto a black wire mesh jar. Much shorter, screw lid with a big mouth and "in the range" price wise. Well I picked up 4 of them and used them all this year and pay attention now cause your all gonna learn something here:
From a bait jar standpoint anything would probably work but one thing that was VERY obvious to me this year is lack of sea lice! Yep. all I can figure is them nasty buggers wash out while assending the stairway to Heaven! My normal habit is to land all the pots, remove the bait jars then dump all the shrimp into my tub to purge. In the past once all this was done I'd have to break out the hose and wash everything down to clean up all the lice. This year I have not had the hose out of the bilge compartment once!
Now let me jerk your chain a bit by saying, I think this washing action is due to the 218 ft per min. that the E-dyne is doing while landing that gear.
The mesh jar thing could be something we all learn something from and if so I'll bet our buddy (steve) will soon have them for sale too!
