CASPER — Three years ago Wyoming Game and Fish Department workers tagged 1,000 walleye at Glendo Reservoir.
Anglers could bring the tags in to department offices for cash rewards ranging from $5 to $100.
It was all part of a study to determine how much impact anglers are having on the walleye population.
Fisheries manager Al Conder says anglers are still finding tags, and the data so far has prompted the department to set a limit on the size of walleye that may be kept.
Starting in January, all walleye less than 15 inches long must be thrown back. Department officials hope the size limit will create a larger class of fish for future anglers.
