Anglers report good fishing trolling and jigging for cutthroat and lake trout. If you want to keep a cutthroat trout from Bear Lake, it must have a healed fin clip (usually the adipose fin). If you catch a cutthroat with all of its fins intact -- even if it's tagged -- you must release it. Have you ever wondered about the lake trout stocked in Bear Lake? According to biologist Scott Tolentino, all of the lake trout stocked into Bear Lake since 2002 are sterile. The sterile fish go through the same spawning behaviors as fertile fish, but they do not produce viable eggs or milt. Bear Lake is stocked cooperatively by the Utah Division of Wildlife and the Idaho Department of Fish and Game. Every year, Utah stocks about 170,000 seven-inch (and larger) cutthroat trout and Idaho stocks about 17,000 six-inch (and larger) lake trout.
