I bet that fish would taste awful
I bet that fish was loaded with fat and tasted great after having a long life in a natural body of water and not a holding pond.
It is possible and definitely has me curious. In most of my experience, smaller fish tend to eat better than larger ones. I also don't think of fish fat being what I want like I do beef, but I could also be way off. Definitely never caught a trout nearly this size 
You should try eating salmon or steelhead sometime. Loaded with fat and great meat.
