You're probably right that most states have no limits but in Indiana (for instance) all non game fish apply towards your bait limit which is in the hundreds per day.I think (someone correct me here) that in most states non-game, non-protected species can be collected without limit.
I am assuming you are reading within one of the links up there. Generally you can posses more than a days limit in the field. Not in the boat but in a cooler or camper etc etc. About keeping them at home I do not see why keeping them in a freezer dead or keeping them in a tank alive is any different. So with that respect I would assume you could go out every day and bring home your limit. At least that is the way it is in most states. You can bring home that many fish a day, every day.
Again you're probably right that most states have no possession limit but In Illinois and Indiana we have a daily limit (the number of fish you can take per day) and a total possession limit (the number of fish you can possess at any given time). The possession limit in the two states is double the daily limit. This law is designed to make sure you only have a double daily limit in your freezer. If you have room for a dozen adult largemouth/Smallmouth/Spotted bass in your aquariums at home.....I need to see your tanks
