seeing as how it shows "fish" outlines and not simply air bladder density differences ??

Air isn't the only density difference factor that Sonar detects ...

There are other substances besides air that also have a different density than water (fish flesh, scales, structure, bottom composition, etc) ...

Air would be in the "less dense" category vs water ...
Flesh, scales, structure, etc would be in the "more dense" category vs water ...

Either side of the "vs water" density would be different than the water density itself ...
