shallow water shot - interpretations?

 I was out crabbing a few weeks ago in the swan.  Between runs i had latched onto a public mooring near elizabeth quay.  Boat was stationary with the stern close to the mooring.  Saw this on the sounder.  Now, if i had been in deeper water i would have been excited by this.  To me it appears to be a surface predator swimming down towards some bait fish on the bottom.  But it could also be something like a flathead lying on the bottom and merely something sinking down through the beam.  What ever is heading down didnt put out a strong echo so it may have been a gobble guts for all i know.

Thoughts?

If the rope was in the beam, it would be a constant (none changing) echo, would it not?  Boat was basically stationary.  Mooring is stationary.

 as you say Randall. Some little fish. Could be a mulloways tail on the very edge of your sounder signal.
