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.


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.
