If you plan on keeping creek chubs overnight or longer. The container needs to be covered. These guys like to jump when in captivity. Knew of a bait shop that decided to seine and sell chubs for the local northern pike and catfish anglers.
I happened to be his first customer the morning after their initial seining adventure. The floor was littered with what would have been beautiful bait.
He didn’t have a dozen left in the tank. That afternoon he designed a cover of wire mesh that covered the six foot tank’s top. After that he always had them for sale. He was getting .75 each or 8$ a dozen. He sold them until the day he closed.
Claimed they brought customers to his shop. That otherwise would have never left their normal baitshops. He always closed during ice season so can’t comment on use or sale during then.
