is there a season and time you can fish for largemouth freshwater bass and what is the rules for claiming a new world record largemouth bass???

You can catch a large size bass any time of the year, but during spawning is when you will have the best chances of doing so. If you are after those that are going to help you get a world’s record you may want to get the help of a well qualified guide. They often know those hidden locations offering larger than normal fish, but they don’t share that information with just anyone.
Make sure you take along plenty of film so that you can record the size and the length of the bass you catch. You need to make sure you have a way to weigh it and to measure it. You need to show that largemouth bass to several people for verification. It can be a good idea to have it stuffed too and then you will have the right documentation.
