Big Coaster Day at Pictured Rocks!
Midwest Region, May 14, 2004
Print Friendly Version
The mouth of the Hurricane River (Michigan) was a busy spot this past week as crews from The U.S. Fish and Wildlife Service's Ashland Fishery Resource Office, Genoa National Fish Hatchery, Iron River National Fish Hatchery, joined staff from Pictured Rocks National Lakeshore, and Northern Michigan University to kick-off a new approach to coaster brook trout reintroduction. A total of 7,500 yearling, Tobin Harbor strain brook trout ranging from seven to 12 inches in length, were stocked into the plunge pool below Hurricane River Falls. Hopes are high among partner members that stocking of these larger fish will result in much improved survival and return over that found with previous years of stocking of fall fingerlings. The fish were produced by Genoa NFH and arrived after the nie-hour trip in outstanding condition.

Volunteers from the community assisted the crews by forming a bucket brigade to move fish from the hatchery trucks to the river, while Dr. Jill Leonard of NMU lead her graduate student crew in installing PIT (Passive Integrated Transponder) tags in 280 of the fish. The tagging is a part of the evaluation and follow up study on the coaster reintroduction at Pictured Rocks designed to evaluate habitat use of these fish of the stocked fish. Throughout the following year, Dr. Leonard's crew will sample surrounding stream habitats, while stationary scanning systems at the mouths of three streams record movement of the fish in or out. Early results have shown that most of the fish have entered Lake Superior and that they are moving along the shoreline. Eight of the 280 fish tagged were located in the lower part of Seven Mile Creek (about five shoreline miles from Hurricane River) within three days of the stocking.
