This is the opening statement on the "fishing regulations" page from the GA DNR:

It is unlawful to take in one day or to possess at any one time, except at a residence or commercial storage facility, more than the daily creel limit for each species. It is unlawful to possess more than a total of 50 individuals of all the game fish listed in this section, except channel and flathead catfish.

To me, the highlighted section is saying that you can ONLY have the daily limit of fish in your possesion unless some are in a "residential or commercial storage facility". The "residential storage facility" is reffering to your home freezer of fridge. They do not say there is a limit to how many fish can be in your "reidential storage facility" so I am assuming you can have as many as you want.....which is defferent from alot of states. The main difference I see is that in FL if you are on a fishing vacation you can have a cooloer in your hotel room with twice the daily bag limit and you will be ok, it seems that in Georgia you can ONLY have the daily bag limit of fish in your possesion unless they are in a freezer.
