Coho Salmon Oncorhynchus kisutch – scientific name

Salmon family Salmonidae.

The Upper Peninsula tributaries offer amazing fishing for pink salmon, king salmon, coho salmon, and steelhead trout. The pinks and king salmon spawn starts in late Aug to early Sep and peaks the later part of Sep. Steelhead Trout and Rainbows and browns follow in October and Cohos will follow into December.

The St. Mary’s River of the Upper Peninsula is home to Michigan’s Atlantic Salmon, Pink Salmon.

Atlantic and Pacific salmon belong to the same family of fish but have different genera, making them separate species. While the Pacific chinook salmon is bigger than the Atlantic salmon, it is the wild Atlantic salmon that tends to taste better than the Pacific salmon types.

Atlantic salmon are found in the northern Atlantic Ocean and in rivers that flow into it. The Great lakes eventually feed into the Atlantic Ocean.

Chinook King- Pacific Ocean, Coho – Pacific Ocean, Chum – Pacific Ocean, Pink- Pacific Ocean, Sockeye – Pacific Ocean, Atlantic Salomon – Atlantic Ocean.

There are seven species of Pacific salmon. Five of them occur in North American waters: chinook, coho, pink, chum, and sockeye.

Kokanee are land-locked sockeye salmon. This means that they do not travel to the ocean and return inland to spawn, instead they complete their entire life cycle in a Lake.

Pacific Salmon and most of the Great Lake Pacific range salmon were introduced into the great lakes in the 50’s and 60’s, that is why there are also populations of Pacific range Salmon that inhabit the Great Lakes.

Coho when spawning both male and female coho salmon can develop a hooked jaw in the shape of a hooked nose or hooked jaw.

Atlantic salmon are the only iteroparous type of salmon, which means that some individuals can recover from spawning, swim back to the great lakes, and return the following year for another spawn.

 

Pacific salmon always die after spawning only Steelhead Trout do not die after the spawn. Most salmon species live 2 to 7 years (4 to 5 average). Steelhead trout can live up to about 11 years.

The most common age of returning and spawning adult salmon is 4 years old. Chinook salmon may return to their spawning grounds after 1 to 3 years in the ocean.

Salmon fishing anglers will troll for them using downriggers, though some anglers drift in the current below the rapids. From shore casting with streamers or soft-plastic jerk baits, or big spoons.

Wild-caught Pacific salmon are typically considered to be the healthiest salmon.

Salmon caught while spawning would taste much different than open water caught salmon. As salmon migrate into freshwater streams to spawn, their bodies begin to degrade to the point where they’re actually decomposing.

Atlantic salmon migrate from Lake Huron into the upper stretches of the St. Mary’s River near the Soo locks. Atlantic’s feed on rainbow smelt in the St. Mary’s during the summers months, preparing for their spawn in late October.

Coho feed near the surface, especially in the morning hours. You your gear should be less than 15 feet deep for Coho (Silver) Salmon. Many Coho are caught in the top 7 feet of water. Chinook will be deeper, but in the morning, they will be feeding up high with the Coho.

Coho salmon are now found in all the Great Lakes. In the Wisconsin waters of Lake Michigan, coho salmon are found from Kenosha north to Sturgeon Bay.

Health : Local waters have PCBs, dioxin, mercury, PFOS, and other chemicals that can be found in fish and stay in our environment for a very long time.
