As long as you legally catch the fish in Minnesota, you have the record. They may want to examine the pond, to see if it could actually produce a fish of that size. They would be looking at fish and forage , as well as depth and chance of Winter Kill — If many little lakes in the area had a severe winter kill 4 years ago, and you claim to catch a record fish that is aged at 8 or 10 years old. They would have some real questions.
Does anybody know if there is a list available, from the state, of where they have “certified” scales???? Some bait shops have scales, but they are not all “certified” — Anyplace that sales items based on weight, would need a certified scale; Grocery stores, feed stores or any other store that would be selling items by the pound. If you can’t find a certified scale, make sure you have a “base line” — weigh a standard item to prove the scale. Your fish is going to drop in weight quickly, so weigh it fast and find some witnesses — also measure the length and girth in front of the witnesses, take pictures and get names and contact info for the witnesses.
Good Luck to all — There are new records out there, just need to catch them.
