    BOISE, Idaho (AP) — About 250,000 rainbow trout died in a sudden disease outbreak at a southwestern Idaho fish hatchery, a loss of about 8 percent of Idaho’s annual output of catchable-sized trout.

    It was the second such outbreak of ichthyophthirius multifilis in as many years at the state Department of Fish and Game hatchery in Nampa. Officials say it likely resulted when stress from overcrowding weakened the fish, making them more susceptible to the parasite.

    The outbreak happened in January, but became public this week because the state agency is trying to manage remaining stocks of 6- to 8-inch fish at its five other hatcheries to make certain lakes and streams still get enough fish to satisfy anglers.
