1 – There’s bad news for salmon in Lake Huron.

A University of Michigan-led study says the lake’s chinook salmon fishery is unlikely to recover due to an ongoing food shortage.

The study says the lake can no longer support the alewife, which is the salmon’s main food source.

A co-author says the study should serve as a reality check when it comes to stocking Chinook salmon in Lake Huron.

Pacific salmon were introduced into the Great Lakes 50 years ago to establish a new recreational fishery and help control alewives, a non-native species.

Computer simulations in the study show that the collapse of the alewife population was caused by a combination of predation by salmon and native lake trout and food limitation tied to invasive mussels.

Lake Huron resource managers are being advised to focus efforts on restoration of native fish species like lake trout, walleye, lake whitefish and lake herring.

2 – April is beach season. At least when it comes to the Alliance for the Great Lakes.

The environmental group is kicking off Adopt-a-Beach program this spring with events throughout the state.

A cleanup is planned for Saturday, April 9, at the Bay City State Recreation Area in Bay County’s Bangor Township.

It starts at 10 a.m. at the state park Visitor Center. You can register online at GreatLakesAdopt.org.

An estimated 25 volunteers will collect trash from the beach.

At the last cleanup in October, items collected from the beach included cigarette butts, food wrappers and beverage bottles and cans, and grocery bags.
