These hearty species are the easiest to keep in captivity as they tolerate warm water and dissolved oxygen as low as 2 to 3 ppm (parts per million). The reward's in keeping those fragile baits that few anglers know how to keep. Oxygen and temperature are the two most critical factors affecting baitfish survival.

How long can you keep mullet alive?

Registered. I've kept them alive for a week in a cube shaped 48qt cooler. But you can't crowd them too much, you have to have a good aerator AND you have to change the water at least once a day.

How do you keep greenbacks alive?

Delicate bait such as shad, greenbacks, and white bait will not survive a day of fishing unless the water flow in the livewell is soft and gentle. Turbulent water will damage the bait and force them to work against the current. Ideal water flow within a live well should be approximately 1 to 2 MPH.
