Pinook a hybrid in the Upper Great Lakes

Image result for images pink salmon
The Pinook is a hybrid crossing of pink salmon with female Chinook salmon on the St. Mary's River in the Great Lakes system.  The Pinook does not die after spawning.

Pink Salmon you may ask?  

Pink salmon, a relative of the lake trout, are from the saltwater
Pacific Ocean. Some of these fish were accidentally washed down
the drain at an experiment station on Lake Superior in 1955 and to
everyone’s surprise, the fish returned to the drain two years later to
spawn. They established themselves in the cold freshwater of Lake
Superior then reached Lake Michigan and Lake Huron via the St.
Mary’s River, which is a freeway for fish. Pink salmon weigh from
three to five pounds at maturity and sometimes reach ten pounds.
The adult male develops a large hump on his back and a hooked jaw.

Return of the Lake Trout

For now, better fisheries management has helped Lake Michigan see a return of lake trout.
The sport has changed for fishermen like Bentley, but he said there’s always been something biting on the end of his line.
Last year was the best in several years, he said. Though king salmon catches remained low, many of the fish from yesteryear, like lake trout, seem to be returning.
“We’ve seen Lake Michigan go through a lot of changes, but it all seems to work out and it always ends up being OK,” Bentley said. “Last two years, I’ve been encouraged by the comeback. I don’t think we’ll ever see the heyday of king salmon, but I think they’ll always be available.”

Praise for The Dynamic Great Lakes

 In her cautionary book, environmental activist and professor Spring enthusiastically explores the Great Lakes, and clearly explains why they should be protected. —Book Sense Nov 22 2003

This is intriguing stuff for adults, but the straightforward presentation also lends itself to use in schools. —Peter Wild U.S. Water News

 Every library should have this book. —Stan Lievense, retired fish biologist MDNR

Worth reading if for no other reason than that the writing is masterfully done…reminded me a little of Rachel Carson’s Silent Spring. —Jonathon David Masters,

This is an impressive little book. Not quite 110 pages long, it’s a read of about an hour or so. The author has, however, managed to jam it full of facts and information about the Great Lakes. The author also sprinkles a strong environmental ethic throughout the book coupled with the belief that the democratic process can make a difference. —Bob Gross, The Oakland Press

 Spring’s handy 108-page primer about the Great Lakes provides the curious with a solid overview of the lakes including their history, physical characteristics, denizens and the threats facing them, particularly from invasive species and pollution. —Dave LeMieux, The Muskegon Chronicle
