Yesterday I filleted 12 coho and that their flesh was of a light orange to orange color not the blood red that I’ve seen in the past. Could this be due to a dietary change.    Any similar observations?    CARPIO

Some say you are what you eat. If the salmon flesh is less red it might be in part due to eating less shrimp. There are a least two fresh water shrimp in Lake MI that typically live in deep water. The native Mysis called opossum shrimp (Mysis relicta) and the relatively recent invasive bloody red shrimp (Hemimysis anomala).

During early Coho season the last three years some of the first catches off Racine were in 150-250fow down 50-100 feet. The stomachs of the Coho were bursting with shrimp and the salmon flesh was brilliant orange. It seemed as the water warmed and the alewife started to show the stomach contents found alewife and no shrimp.

The abundant alewife this year finds the Coho closer to shore and most caught in the upper part of the water column. Thus my guess is less shrimp and more alewife in their diet renders the lighter color. It seems to me that is why Chinook flesh is almost always lighter than Coho. Chinooks eat almost all alewife but Coho will eat what’s available.

The picture is the stomach contents of Coho I caught off Racine May 4. 2017 in around 230 fow.

There is no such thing as an undernourished salmon in Lake Michigan right now. Meat color has nothing to do with it. It could be something as simple as the fish bled out in the cooler or not enough ice. There are hundreds of 30LB kings in the lake right now. They have to be eating something!! Undernourished ya have to be kidding me. Lol ugggggg.

Ummmmm, really?

There was two over 30# and piles above 20# registered in the Salmon Cup in Sheboygan last weekend. 

Two coolers were brought in with their 5 kings averaging over 20# each.

There is more than plenty for these fish to eat right now.

They are getting less to eat no doubt....  rarely see the 20+ kings that were common in the 80s

12.  I am in error , I should have said,like you did,not malnourished, they are probably eating whatever they can find.    We saw no bait on the sonar yesterday.    The fish were on the small size but not thin.   CARPIO

diet does impact color of meat, does not necessarily mean malnourished.

Funny you posted this, I just was reading an article from 1966 where Sen. Philip Hart asked Congress to provide funding to stock salmon,striped bass and steelhead to reduce the alewife in lake Michigan.
