I'm looking for advice. I live on a river and have a concrete bottom boat basis that's approximately 25' x 16' and depth can fluctuate between 6" and 30", most often close to 2' depth.

I'm retiring next month and want to supplement by income by raising shiners. I'm in Florida; we have gators, otters, snakes, turtles, and all kinds of bird and larger fish as predators.

My intent is to build 6 containers, think aquariums with screen versus glass, so I can sequestor by size, gender etc. I'll take all the advice I can get on what to use and how to detract predators. And I thank you in advance for your replies!
