Ye Ol Live Well Bait Tank

[AM3R1CN]

Hi Kayak Angler Folks

I'm interested in making a bait tank for saltwater (ocean) kayak fishing, as all new kayak fisherman must do.

Could one just use the existing scupper holes in their kayak and put a couple pvc/rubber tubes through the scupper holes (as long as there were extra scupper holes available) and seal them so the water could only go up through the holes (with one way directional valves, water goes in only) into the bait tank and overflow water drains out the top of the bait tank. Wouldn't this be an incredibly simpler version of this whole bait tank design fiasco with aerators, batteries etc?

Wouldn't the simple rocking back and forth of the boat through waves be enough to push water up through these valves and keep fresh oxygenated water in the live well?

THANK YOU!
