Name that Return

[GregAndrew]

So, I have been playing around with logging my sonar, while out on the water. Then, in conjunction with my downrigger camera I have been comparing what I see on the FF with what my camera sees on the bottom. All of the images are from pictures of my FF, while playing back the logged sonar (read too cheap to pay for a program that will translate my sonar logs or screenshots to something usable on the PC). My new FF only is available in 83/200khz, so about all of my images will be on 83khz. Anyway, here are the first couple to take a crack at.

sorry, here is the other image.

I'd say a small school of yellows over some micro bait. Where I'm from, those would be red crab but not sure you are seeing them up there. Definitely worth dropping a jig down. Not sure what the point is of the 2nd photo, other that seeing your downrigger cable and more micro bait. Thanks for the waypoint BTW. Although I already had one about 200 yards to the WSW of this one.

It's the chupacabra

He thinks hes got the corner on crabs...
We got crab man.

I like this game. I'd say the first one looks like bait on the bottom and a schooling predatory fish on top. Deff a school of something rolling through. Yellowtail sometime mark like but can also be some fat jumbo mackerel. Not wormy enough for WSb and not skinny enough for barracuda. So I say yellowtail.

The bottom screenshot is probably a mixture of bait and whitefish based on depth.

I was going to guess a yo-yo iron being retrieved back up after dropping on what looks like red crab.

Bait is the straight line across the bottom with a halibut coming up to play with it.... Maybe?

That depends on a few factors, that are interrelated. But it comes down to the number of fish and their vertical distribution in the area of view. In these cases, I am on 83khz (my wide cone angle frequency). That gives me a better angle to capture something, but it also jams all of that info into each vertical line the FF draws. As long as the fish are fairly thick and well distributed vertically, they can blot out the screen.

Straight line across the bottom is my downrigger ball and camera setup.

This is a good guess. But even most BSB are not going to give you the color of a harder return (the red in the pic) at that distance. One of the very large models might, or if you have your colorline cranked up, that might do it also.


This last mark was a Dolphin passing by the camera.


Ok, here is an easy one.

I believe the last ones are called "What are boner fish for $500 Alex?"

Here is one last one that is pretty kewl to figure out everything that is going on in. And how things change at a distance.

This didn’t suck .

Ok, got some good possibilities mentioned (and then there was Jorge ). The first log was an assortment of quite a few species over an active structure spot. There were White Fish, Blacksmith Perch, several species of Rock Fish, Sheepsheads and others. No Red Crabs, microbaits or any "baitfish" at all for that matter. I did not get a visual on the predators nearer the surface on camera though.

The second log was a sea of White Fish almost exclusively, but until I pulled the camera up, I was only getting a glimpse of the bottom 15' or so.

The third log shows about 3 minutes of recording time. The first 20 seconds is a decent sized Halibut eyeballing my bait. Then, at least 1 nice YT joins in on the ogling. They both continue to look but not bite for the next minute before the Halibut decides the grapes are sour anyway. At least 1 YT comes in and out of the screen for the next couple of minutes before they too decide the grapes are sour.


Here is a new one. I will give you a hint, cause this one is pretty hard. Notice the color, size and depth.
