shallow water sounder shots - mud (swan river)

simrad nss7 shots from last weekend when I was crabbing.  The shallower water is under the narrows in between the northern bank and the northern pylon.

 

 

The deeper shots are over near como buoy.  The only explanation I can give for the weaker echos in the top half of the water column is jellyfish.  anyone want to comment on that?  not sure if they show up on sounders?

 I get those weak echo's up river too, even with the gain turned right down. I believe they are mostly jelly fish and other stuf drifting with the tide. 

At the moment I am also seeing alot of bait, and if its spread out it clutters the screen too.

 In the bottom pics, I would say weed.  In the top pic, the clumps of green could be weed or small bait.  I think the stronger bottom echo in the top pic (with a bit of red in it) could be a weed covered rock with a fish sitting off the top of it.

 The thin line across the top is the lighter layer of silt,leaves and mud?

 

Anything caught around these spots?

 I was crabbing at the time and just watching the sounder in my spare time.  No lines in the water.

 Great to see these shots. I've just installed a Dragonfly 7 and was getting very similar images with the little spots. Most of mine were little arches though.
