Fish: Lake Trout

Strange Dark Green Liquid from Laker

Post By: bouldertrout      Posted: 1/16/2023 11:00:42 PM     Points: 31    
In cleaning a laker (16" from Granby), the filet knife ripped the fish intestine and a lot of lark green (blackish) liquid came out. I did some search online and found that the fish bile can be yellowish, but not dark green. Any thoughts what that could be and if the fish is safe to eat cooked?

Sounds like it might have been digested bugs (scuds/midges/whatever). That's my guess anyway.

All natural. Nothing at all to worry about. Just digested diet as D.D. suggested. As with any other animal, don't eat the green goo out of the intestines 😒

Thank you all! Appreciate the insight!

I have never seen dark green liquid come out of a lake trout but when I clean kokanee they are always full of dark green liquid. The reason is that the kokanee eat nothing but zooplankton. I have noticed that some of the rainbows I catch over deep water at eleven mile also have dark green liquid in their large intestine.
