If you know what shrimp look like on sonar, then you’ll know how many are in a spot. If not, you’ll be left guessing.
Earlier this summer I went fishing out of Hopedale Marina, looking for speckled trout.
Well, lemme tell ya somethin', it was one of those days you really couldn't screw it up.
There weren't fish at every single stop, no.
Hell, some spots had nothing but gafftops or ladyfish, but we don't stay and fish those, now do we?
Didn't think so.
But it was that kinda day you could show a little determination, move with a purpose and eventually limit out on speckled trout.
And that's what happened, catching (and releasing) 30 keeper specks before heading home.
Anyways, the wind wasn't blowing very hard, and the sun was out, so the conditions were right for seagulls to locate jumping shrimp.
And did they!
Running from one spot to the next revealed a good-sized flock of seagulls going absolutely nuts on shrimp across a wide area, which I estimate to have been about the size of a football field.
Casting a line was the first course of action, but the truth was the majority of trout were throwbacks.
On a day like that when I'm by myself, and don't need to catch fish, it's easy to "leave fish to find fish".
After all, knowing where they are is more important than catching them.
The more spots I know they're biting at, the better!
But, I couldn't leave without getting some video and scanning the shrimp for educational purposes.
What the side imaging sonar revealed was interesting, to say the least.
Side Imaging Shrimp
A couple passes revealed exactly how much shrimp was in the water.
How much? A lot more than what could be seen from the surface.
It almost looks like grass, doesn't it?
But it's not. That area is too salty for aquatic grass to grow that thick, like what we see towards "fresher" marsh in Hopedale and Delacroix.
The image clearly depicts shrimp and fish swimming around them, with the shrimp being the large, fuzzy masses and fish being the smaller, solid masses.
These fish are most likely speckled trout, gafftops and maybe smaller pogies.
Does that make sense? Questions or something to add? Comment at the bottom!

If side imaging sonar is completely new to you, then I recommend reading this article.
It details what is what on the screen, like the black part, line in the middle and everything out to the side.
