Funny you should ask. I just asked my business manager, Mike Loewen, to find out that very question. So far, he has found several state agencies which have software but are unwilling to share it, considering it "proprietary." Scratching my head on that one. What we do here, though, is to create a spreadsheet, create columns for length and weight, another for date, and another for miscellaneous notes. We log each fish, the create an x-y graph. Computer savvy people can add the Wr 100 tables for specific species, for comparisons. But, we are looking for something user friendly we can provide landowners.
