Temperature sensitivity on your fish finder...
 

I don't know if you fishermen are aware of this, but fish species have
a preferred temperature range.

Of course the problem is that temperatures in fresh and salt water can
vary with depth/current/tide in that order. You can correlate some
temperatures based on surface readings - it's not to hard to do.

How many of you folks do that? I ask because a friend of mine sent me
an email about his experience with his transducer which was reading
four degrees too low. That can affect a fishing trip big time.

Personally, I never even considered it thinking that four degrees
wouldn't have any effect, but apparently it does - four degrees can
take you right out of the preferred temp range for a lot of fish.

Something to think about when your getting ready in the Spring - check
the accuracy of your transducer for temperature.

You are beginning to sound like one of those Navy sonar geeks. Inversion
layers and all that.

Even though I don't fish, I happened to watch a 'fishing show' where the
host talked about barometric pressure and the effect it has on fish
activity.
Have to admit...it was mildly interesting.

I paid closer attention to water temps when we lived in Florida and I
fished a lot. Not so much up here. Once you are out of the shallows, the
Bay temps in the mid-Bay area don't vary much, and there isn't a lot of
sight fishing, so the temps you see on your finder don't really reflect
what the temps might be 20 or 40 feet below the surface. There are a
couple of outflows from power plants, though, where there are much
higher temps than usual and in the colder months, everyone goes there to
fish.

It's amazing what weather in general will do to fish. I was fishing in
a swamp in FL one time, and there was a place where a spring came up,
the normally tanin stained water was crystal clear. My canoe drifted
right over a decent sized bass. That morning a cold front had moved
in. Now, here's this bass in a couple of feet of water, my worm went
right over him, he didn't even move. So, just to see what was up, I
stuck a paddle in the sand to stop and I rubbed that worm all over his
face, even tapping him a little with the bullet weight. He never even
flinched. Only when I startled him by back padling a little.

We look for the Thermocline in the lakes we fish. Will show up on good
sonar. sometimes I think my Furuno is to good for inland lakes and rivers
as it displays algae in the water.
