I'm no pro at this but will try to chime in on what I think.
Marked up the pic a little bit and re-attached.
Looks like the fish is hungry to me. If it was full the stomach would be more pronounced. However, this could also be a female that has recently spawned and is working to recover.
The tail is interesting to me. Looks to be some sort of indention at the 2/3 mark of the fish and the tail itself looks thin.
Tough to tell with scaling and cropping needed to get to 2mg max files but that's my take.
This is why the length and weights of fish are so important. Both males and female LMB are at their worst RW right after spawn. The male builds and guards the nest while female deposits her eggs. Making the babies is work for them.
With that in mind, below is a link to a
Relative Weight Chart that was posted on the forum previously.
Keep in mind that it doesn't have a curve for time of year for the fish so you have to guess a little bit.
15" bass on average would weigh 1.8 lbs. Likely wouldn't hit this number just after spawning and conversely might be heavier than this going into fall after both recovering from spawn and stocking up for winter.
Without the length and weight it's all subjective guessing.
